This plugin is designed\nto be as frictionless and easy to use as possible while seamlessly integrating all of ImGui's features into UE's\necosystem.\n\n## Features\n\n* **Multi-viewports**: Pull ImGui windows out of the application's frame ([read more](https://github.com/ocornut/imgui/wiki/Multi-Viewports))\n* **Docking**: Combine and tear apart ImGui windows to create custom layouts ([read more](https://github.com/ocornut/imgui/wiki/Docking))\n* **Editor support**: Draw ImGui windows in Unreal Editor outside of game sessions\n* **Play-in-Editor support**: Each PIE session has its own ImGui context\n* **Program support**: Use ImGui in programs and standalone Slate applications\n* **Remote drawing**: Connect to headless (e.g. dedicated server) or remote sessions\n\n## Usage\n\n1. Clone this repository into your project's `Plugins` directory\n2. Add `ImGui` as a public or private dependency to your module's `Build.cs` file:\n\n\t```c#\n\tPublicDependencyModuleNames.Add(\"ImGui\");\n\t```\n\n3. Include `imgui.h` and prior to using any ImGui functions create a local scoped context:\n\n\t```c++\n\t#pragma once\n\n\t#include \n\t#include \n\n\t#include \"ImGuiActor.generated.h\"\n\n\tUCLASS()\n\tclass AImGuiActor : public AActor\n\t{\n\t\tGENERATED_BODY()\n\n\tpublic:\n\t\tAImGuiActor()\n\t\t{\n\t\t\tPrimaryActorTick.bCanEverTick = true;\n\t\t}\n\n\t\tvirtual void Tick(float DeltaTime) override\n\t\t{\n\t\t\tSuper::Tick(DeltaTime);\n\n\t\t\tconst ImGui::FScopedContext ScopedContext;\n\t\t\tif (ScopedContext)\n\t\t\t{\n\t\t\t\t// Your ImGui code goes here!\n\t\t\t\tImGui::ShowDemoWindow();\n\t\t\t}\n\t\t}\n\t};\n\t```\n\nThis \"scoped context\" mechanism will push the appropriate ImGui context and pop it once it's gone out of scope. It's\nadvised to check the `ScopedContext` like the example above to ensure that it's safe to draw.\n\n## Remote drawing\n\nA prebuilt binary of the [NetImGui Server](https://github.com/sammyfreg/netImgui) application is included in\n`Source/ThirdParty/NetImGuiServer`. This application allows connecting to ImGui sessions either locally or on a remote\ndevice (e.g. dedicated server, console, mobile device).\n\nThere are two command-line arguments allowing you to automatically connect to a NetImGui Server:\n- Specifying `-ImGuiHost=Host` will attempt to automatically connect to a NetImGui Server on the specified host using\nthe default port (8888) though this can be overridden using `-ImGuiPort=Port`; note that the host must already be\nrunning the NetImGui Server application otherwise this will be unsuccessful.\n- Specifying just `-ImGuiPort=Port` will attempt to automatically listen for a NetImGui Server connection. This is often\nthe more convenient approach as you can then connect using NetImGui Server at any point in your session.\n\nAlternatively you can drive this in code using `FImGuiContext::Connect` and `FImGuiContext::Listen` respectively:\n\n```c++\nconst ImGui::FScopedContext ScopedContext;\nif (ScopedContext.IsValid())\n{\n\tScopedContext->Listen(8888);\n}\n```\n\n## Usage in programs\n\nYou can utilise this plugin in Unreal programs and Slate applications, though for releases prior to UE 5.4 the latter\nwill require integrating [this PR](https://github.com/EpicGames/UnrealEngine/pull/11088).\n\nYou can either initialise an ImGui context manually using `FImGuiContext::Create` and use the remote drawing\nfunctionality outlined in the section above, or attach ImGui to a Slate application using\n`FImGuiModule::CreateWindowContext`.\n\nEither way you will likely need to manually call `FImGuiContext::BeginFrame` and `FImGuiContext::EndFrame` at\nappropriate points in your application's main loop, as they usually rely on delegates fired from `FEngineLoop::Tick`\nwhich is often not executed in standalone programs for obvious reasons." }, { "path": "Source/ImGui/ImGui.Build.cs", "content": "using UnrealBuildTool;\n\npublic class ImGui : ModuleRules\n{\n\tprotected virtual bool WithImPlot => true;\n\tprotected

Tweak value.\n - Arrow keys + Alt, Shift Tweak slower, tweak faster (when using arrow keys).\n - Enter Activate item (prefer text input when possible).\n - Space Activate item (prefer tweaking with arrows when possible).\n - Escape Deactivate item, leave child window, close popup.\n - Page Up, Page Down Previous page, next page.\n - Home, End Scroll to top, scroll to bottom.\n - Alt Toggle between scrolling layer and menu layer.\n - Ctrl+Tab then Ctrl+Arrows Move window. Hold Shift to resize instead of moving.\n - Output when ImGuiConfigFlags_NavEnableKeyboard set,\n - io.WantCaptureKeyboard flag is set when keyboard is claimed.\n - io.NavActive: true when a window is focused and it doesn't have the ImGuiWindowFlags_NoNavInputs flag set.\n - io.NavVisible: true when the navigation cursor is visible (usually goes to back false when mouse is used).\n\n - GAMEPAD CONTROLS\n - Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.\n - Particularly useful to use Dear ImGui on a console system (e.g. PlayStation, Switch, Xbox) without a mouse!\n - Download controller mapping PNG/PSD at http://dearimgui.com/controls_sheets\n - Backend support: backend needs to:\n - Set 'io.BackendFlags |= ImGuiBackendFlags_HasGamepad' + call io.AddKeyEvent/AddKeyAnalogEvent() with ImGuiKey_Gamepad_XXX keys.\n - For analog values (0.0f to 1.0f), backend is responsible to handling a dead-zone and rescaling inputs accordingly.\n Backend code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.).\n - If you need to share inputs between your game and the Dear ImGui interface, the easiest approach is to go all-or-nothing,\n with a buttons combo to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved.\n\n - REMOTE INPUTS SHARING & MOUSE EMULATION\n - PS4/PS5 users: Consider emulating a mouse cursor with DualShock touch pad or a spare analog stick as a mouse-emulation fallback.\n - Consoles/Tablet/Phone users: Consider using a Synergy 1.x server (on your PC) + run examples/libs/synergy/uSynergy.c (on your console/tablet/phone app)\n in order to share your PC mouse/keyboard.\n - See https://github.com/ocornut/imgui/wiki/Useful-Extensions#remoting for other remoting solutions.\n - On a TV/console system where readability may be lower or mouse inputs may be awkward, you may want to set the io.ConfigNavMoveSetMousePos flag.\n Enabling io.ConfigNavMoveSetMousePos + ImGuiBackendFlags_HasSetMousePos instructs Dear ImGui to move your mouse cursor along with navigation movements.\n When enabled, the NewFrame() function may alter 'io.MousePos' and set 'io.WantSetMousePos' to notify you that it wants the mouse cursor to be moved.\n When that happens your backend NEEDS to move the OS or underlying mouse cursor on the next frame. Some of the backends in examples/ do that.\n (If you set the NavEnableSetMousePos flag but don't honor 'io.WantSetMousePos' properly, Dear ImGui will misbehave as it will see your mouse moving back & forth!)\n (In a setup when you may not have easy control over the mouse cursor, e.g. uSynergy.c doesn't expose moving remote mouse cursor, you may want\n to set a boolean to ignore your other external mouse positions until the external source is moved again.)\n\n\n PROGRAMMER GUIDE\n ================\n\n READ FIRST\n ----------\n - Remember to check the wonderful Wiki: https://github.com/ocornut/imgui/wiki\n - Your code creates the UI every frame of your application loop, if your code doesn't run the UI is gone!\n The UI can be highly dynamic, there are no construction or destruction steps, less superfluous\n data retention on your side, less state duplication, less state synchronization, fewer bugs.\n - Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features.\n Or browse https://pthom.github.io/imgui_manual_online/manual/imgui_manual.html for interactive web version.\n - The library is designed to be built from sources. Avoid pre-compiled binaries and packaged versions. See imconfig.h to configure your build.\n - Dear ImGui is an implementation of the IMGUI paradigm (immediate-mode graphical user interface, a term coined by Casey Muratori).\n You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links in Wiki.\n - Dear ImGui is a \"single pass\" rasterizing implementation of the IMGUI paradigm, aimed at ease of use and high-performances.\n For every application frame, your UI code will be called only once. This is in contrast to e.g. Unity's implementation of an IMGUI,\n where the UI code is called multiple times (\"multiple passes\") from a single entry point. There are pros and cons to both approaches.\n - Our origin is on the top-left. In axis aligned bounding boxes, Min = top-left, Max = bottom-right.\n - Please make sure you have asserts enabled (IM_ASSERT redirects to assert() by default, but can be redirected).\n If you get an assert, read the messages and comments around the assert.\n - This codebase aims to be highly optimized:\n - A typical idle frame should never call malloc/free.\n - We rely on a maximum of constant-time or O(N) algorithms. Limiting searches/scans as much as possible.\n - We put particular energy in making sure performances are decent with typical \"Debug\" build settings as well.\n Which mean we tend to avoid over-relying on \"zero-cost abstraction\" as they aren't zero-cost at all.\n - This codebase aims to be both highly opinionated and highly flexible:\n - This code works because of the things it choose to solve or not solve.\n - C++: this is a pragmatic C-ish codebase: we don't use fancy C++ features, we don't include C++ headers,\n and ImGui:: is a namespace. We rarely use member functions (and when we did, I am mostly regretting it now).\n This is to increase compatibility, increase maintainability and facilitate use from other languages.\n - C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types.\n See FAQ \"How can I use my own math types instead of ImVec2/ImVec4?\" for details about setting up imconfig.h for that.\n We can can optionally export math operators for ImVec2/ImVec4 using IMGUI_DEFINE_MATH_OPERATORS, which we use internally.\n - C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction\n (so don't use ImVector in your code or at our own risk!).\n - Building: We don't use nor mandate a build system for the main library.\n This is in an effort to ensure that it works in the real world aka with any esoteric build setup.\n This is also because providing a build system for the main library would be of little-value.\n The build problems are almost never coming from the main library but from specific backends.\n\n\n HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI\n ----------------------------------------------\n - Update submodule or copy/overwrite every file.\n - About imconfig.h:\n - You may modify your copy of imconfig.h, in this case don't overwrite it.\n - or you may locally branch to modify imconfig.h and merge/rebase latest.\n - or you may '#define IMGUI_USER_CONFIG \"my_config_file.h\"' globally from your build system to\n specify a custom path for your imconfig.h file and instead not have to modify the default one.\n\n - Overwrite all the sources files except for imconfig.h (if you have modified your copy of imconfig.h)\n - Or maintain your own branch where you have imconfig.h modified as a top-most commit which you can regularly rebase over \"master\".\n - You can also use '#define IMGUI_USER_CONFIG \"my_config_file.h\" to redirect configuration to your own file.\n - Read the \"API BREAKING CHANGES\" section (below). This is where we list occasional API breaking changes.\n If a function/type has been renamed / or marked obsolete, try to fix the name in your code before it is permanently removed\n from the public API. If you have a problem with a missing function/symbols, search for its name in the code, there will\n likely be a comment about it. Please report any issue to the GitHub page!\n - To find out usage of old API, you can add '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' in your configuration file.\n - Try to keep your copy of Dear ImGui reasonably up to date!\n\n\n GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE\n ---------------------------------------------------------------\n - See https://github.com/ocornut/imgui/wiki/Getting-Started.\n - Run and study the examples and demo in imgui_demo.cpp to get acquainted with the library.\n - In the majority of cases you should be able to use unmodified backends files available in the backends/ folder.\n - Add the Dear ImGui source files + selected backend source files to your projects or using your preferred build system.\n It is recommended you build and statically link the .cpp files as part of your project and NOT as a shared library (DLL).\n - You can later customize the imconfig.h file to tweak some compile-time behavior, such as integrating Dear ImGui types with your own maths types.\n - When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them.\n - Dear ImGui never touches or knows about your GPU state. The only function that knows about GPU is the draw function that you provide.\n Effectively it means you can create widgets at any time in your code, regardless of considerations of being in \"update\" vs \"render\"\n phases of your own application. All rendering information is stored into command-lists that you will retrieve after calling ImGui::Render().\n - Refer to the backends and demo applications in the examples/ folder for instruction on how to setup your code.\n - If you are running over a standard OS with a common graphics API, you should be able to use unmodified imgui_impl_*** files from the examples/ folder.\n\n\n HOW A SIMPLE APPLICATION MAY LOOK LIKE\n --------------------------------------\n\n USING THE EXAMPLE BACKENDS (= imgui_impl_XXX.cpp files from the backends/ folder).\n The sub-folders in examples/ contain examples applications following this structure.\n\n // Application init: create a dear imgui context, setup some options, load fonts\n ImGui::CreateContext();\n ImGuiIO& io = ImGui::GetIO();\n // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls.\n // TODO: Fill optional fields of the io structure later.\n // TODO: Load TTF/OTF fonts if you don't want to use the default font.\n\n // Initialize helper Platform and Renderer backends (here we are using imgui_impl_win32.cpp and imgui_impl_dx11.cpp)\n ImGui_ImplWin32_Init(hwnd);\n ImGui_ImplDX11_Init(g_pd3dDevice, g_pd3dDeviceContext);\n\n // Application main loop\n while (true)\n {\n // Feed inputs to dear imgui, start new frame\n ImGui_ImplDX11_NewFrame();\n ImGui_ImplWin32_NewFrame();\n ImGui::NewFrame();\n\n // Any application code here\n ImGui::Text(\"Hello, world!\");\n\n // Render dear imgui into framebuffer\n ImGui::Render();\n ImGui_ImplDX11_RenderDrawData(ImGui::GetDrawData());\n g_pSwapChain->Present(1, 0);\n }\n\n // Shutdown\n ImGui_ImplDX11_Shutdown();\n ImGui_ImplWin32_Shutdown();\n ImGui::DestroyContext();\n\n To decide whether to dispatch mouse/keyboard inputs to Dear ImGui to the rest of your application,\n you should read the 'io.WantCaptureMouse', 'io.WantCaptureKeyboard' and 'io.WantTextInput' flags!\n Please read the FAQ entry \"How can I tell whether to dispatch mouse/keyboard to Dear ImGui or my application?\" about this.\n\n\nUSING CUSTOM BACKEND / CUSTOM ENGINE\n------------------------------------\n\nIMPLEMENTING YOUR PLATFORM BACKEND:\n -> see https://github.com/ocornut/imgui/blob/master/docs/BACKENDS.md for basic instructions.\n -> the Platform backends in impl_impl_XXX.cpp files contain many implementations.\n\nIMPLEMENTING YOUR RenderDrawData() function:\n -> see https://github.com/ocornut/imgui/blob/master/docs/BACKENDS.md\n -> the Renderer Backends in impl_impl_XXX.cpp files contain many implementations of a ImGui_ImplXXXX_RenderDrawData() function.\n\nIMPLEMENTING SUPPORT for ImGuiBackendFlags_RendererHasTextures:\n -> see https://github.com/ocornut/imgui/blob/master/docs/BACKENDS.md\n -> the Renderer Backends in impl_impl_XXX.cpp files contain many implementations of a ImGui_ImplXXXX_UpdateTexture() function.\n\n Basic application/backend skeleton:\n\n // Application init: create a Dear ImGui context, setup some options, load fonts\n ImGui::CreateContext();\n ImGuiIO& io = ImGui::GetIO();\n // TODO: set io.ConfigXXX values, e.g.\n io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard; // Enable keyboard controls\n\n // TODO: Load TTF/OTF fonts if you don't want to use the default font.\n io.Fonts->AddFontFromFileTTF(\"NotoSans.ttf\");\n\n // Application main loop\n while (true)\n {\n // Setup low-level inputs, e.g. on Win32: calling GetKeyboardState(), or write to those fields from your Windows message handlers, etc.\n // (In the examples/ app this is usually done within the ImGui_ImplXXX_NewFrame() function from one of the demo Platform Backends)\n io.DeltaTime = 1.0f/60.0f; // set the time elapsed since the previous frame (in seconds)\n io.DisplaySize.x = 1920.0f; // set the current display width\n io.DisplaySize.y = 1280.0f; // set the current display height here\n io.AddMousePosEvent(mouse_x, mouse_y); // update mouse position\n io.AddMouseButtonEvent(0, mouse_b[0]); // update mouse button states\n io.AddMouseButtonEvent(1, mouse_b[1]); // update mouse button states\n\n // Call NewFrame(), after this point you can use ImGui::* functions anytime\n // (So you want to try calling NewFrame() as early as you can in your main loop to be able to use Dear ImGui everywhere)\n ImGui::NewFrame();\n\n // Most of your application code here\n ImGui::Text(\"Hello, world!\");\n MyGameUpdate(); // may use any Dear ImGui functions, e.g. ImGui::Begin(\"My window\"); ImGui::Text(\"Hello, world!\"); ImGui::End();\n MyGameRender(); // may use any Dear ImGui functions as well!\n\n // End the dear imgui frame\n // (You want to try calling EndFrame/Render as late as you can, to be able to use Dear ImGui in your own game rendering code)\n ImGui::EndFrame(); // this is automatically called by Render(), but available\n ImGui::Render();\n\n // Update textures\n ImDrawData* draw_data = ImGui::GetDrawData();\n for (ImTextureData* tex : *draw_data->Textures)\n if (tex->Status != ImTextureStatus_OK)\n MyImGuiBackend_UpdateTexture(tex);\n\n // Render dear imgui contents, swap buffers\n MyImGuiBackend_RenderDrawData(draw_data);\n SwapBuffers();\n }\n\n // Shutdown\n ImGui::DestroyContext();\n\n\n\n API BREAKING CHANGES\n ====================\n\n Occasionally introducing changes that are breaking the API. We try to make the breakage minor and easy to fix.\n Below is a change-log of API breaking changes only. If you are using one of the functions listed, expect to have to fix some code.\n When you are not sure about an old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all imgui files.\n You can read releases logs https://github.com/ocornut/imgui/releases for more details.\n\n(Docking/Viewport Branch)\n - 2026/XX/XX (1.XXXX) - when multi-viewports are enabled, all positions will be in your natural OS coordinates space. It means that:\n - reference to hard-coded positions such as in SetNextWindowPos(ImVec2(0,0)) are probably not what you want anymore.\n you may use GetMainViewport()->Pos to offset hard-coded positions, e.g. SetNextWindowPos(GetMainViewport()->Pos)\n - likewise io.MousePos and GetMousePos() will use OS coordinates.\n If you query mouse positions to interact with non-imgui coordinates you will need to offset them, e.g. subtract GetWindowViewport()->Pos.\n\n - 2026/01/08 (1.92.6) - Commented out legacy names obsoleted in 1.90 (Sept 2023): 'BeginChildFrame()' --> 'BeginChild()' with 'ImGuiChildFlags_FrameStyle'.

'IM_OFFSETOF()' --> 'offsetof()'.\n - 2026/01/07 (1.92.6) - Popups: changed compile-time 'ImGuiPopupFlags popup_flags = 1' default value to be '= 0' for BeginPopupContextItem(), BeginPopupContextWindow(), BeginPopupContextVoid(), OpenPopupOnItemClick(). Default value has same meaning before and after.\n - Refer to GitHub topic #9157 if you have any question.\n - Before this version, those functions had a 'ImGuiPopupFlags popup_flags = 1' default value in their function signature.\n Explicitly passing a literal 0 meant ImGuiPopupFlags_MouseButtonLeft. The default literal 1 meant ImGuiPopupFlags_MouseButtonRight.\n This was introduced by a change on 2020/06/23 (1.77) while changing the signature from 'int mouse_button' to 'ImGuiPopupFlags popup_flags' and trying to preserve then-legacy behavior.\n We have now changed this behavior to cleanup a very old API quirk, facilitate use by bindings, and to remove the last and error-prone non-zero default value.\n Also because we deemed it extremely rare to use those helper functions with the Left mouse button! As using the LMB would generally be triggered via another widget, e.g. a Button() + a OpenPopup()/BeginPopup() call.\n - Before: The default = 1 means ImGuiPopupFlags_MouseButtonRight. Explicitly passing a literal 0 means ImGuiPopupFlags_MouseButtonLeft.\n - After: The default = 0 means ImGuiPopupFlags_MouseButtonRight. Explicitly passing a literal 1 also means ImGuiPopupFlags_MouseButtonRight (if legacy behavior are enabled) or will assert (if legacy behavior are disabled).\n - TL;DR: if you don't want to use right mouse button for popups, always specify it explicitly using a named ImGuiPopupFlags_MouseButtonXXXX value.\n Recap:\n - BeginPopupContextItem(\"foo\"); // Behavior unchanged (use Right button)\n - BeginPopupContextItem(\"foo\", ImGuiPopupFlags_MouseButtonLeft); // Behavior unchanged (use Left button)\n - BeginPopupContextItem(\"foo\", ImGuiPopupFlags_MouseButtonLeft | xxx); // Behavior unchanged (use Left button + flags)\n - BeginPopupContextItem(\"foo\", ImGuiPopupFlags_MouseButtonRight | xxx); // Behavior unchanged (use Right button + flags)\n - BeginPopupContextItem(\"foo\", 1); // Behavior unchanged (as a courtesy we legacy interpret 1 as ImGuiPopupFlags_MouseButtonRight, will assert if disabling legacy behaviors.\n - BeginPopupContextItem(\"foo\", 0); // !! Behavior changed !! Was Left button. Now will defaults to Right button! --> Use ImGuiPopupFlags_MouseButtonLeft.\n - BeginPopupContextItem(\"foo\", ImGuiPopupFlags_NoReopen); // !! Behavior changed !! Was Left button + flags. Now will defaults to Right button! --> Use ImGuiPopupFlags_MouseButtonLeft | xxx.\n - 2025/12/23 (1.92.6) - Fonts: AddFontDefault() now automatically selects an embedded font between the new scalable AddFontDefaultVector() and the classic pixel-clean AddFontDefaultBitmap().\n The default selection is based on (style.FontSizeBase * FontScaleMain * FontScaleDpi) reaching a small threshold, but old codebases may not set any of them properly. As as a result, it is likely that old codebase may still default to AddFontDefaultBitmap().\n Prefer calling either based on your own logic. You can call AddFontDefaultBitmap() to ensure legacy behavior.\n - 2025/12/23 (1.92.6) - Fonts: removed ImFontConfig::PixelSnapV added in 1.92 which turns out is unnecessary (and misdocumented). Post-rescale GlyphOffset is always rounded.\n - 2025/12/17 (1.92.6) - Renamed helper macro IM_ARRAYSIZE() -> IM_COUNTOF(). Kept redirection/legacy name for now.\n - 2025/12/11 (1.92.6) - Hashing: handling of \"###\" operator to reset to seed within a string identifier doesn't include the \"###\" characters in the output hash anymore.\n - Before: GetID(\"Hello###World\") == GetID(\"###World\") != GetID(\"World\")\n - After: GetID(\"Hello###World\") == GetID(\"###World\") == GetID(\"World\")\n - This has the property of facilitating concatenating and manipulating identifiers using \"###\", and will allow fixing other dangling issues.\n - This will invalidate hashes (stored in .ini data) for Tables and Windows that are using the \"###\" operators. (#713, #1698)\n - 2025/11/24 (1.92.6) - Fonts: Fixed handling of `ImFontConfig::FontDataOwnedByAtlas = false` which did erroneously make a copy of the font data, essentially defeating the purpose of this flag and wasting memory.\n (trivia: undetected since July 2015, this is perhaps the oldest bug in Dear ImGui history, albeit for a rarely used feature, see #9086)\n HOWEVER, fixing this bug is likely to surface bugs in user code using `FontDataOwnedByAtlas = false`.\n - Prior to 1.92, font data only needed to be available during the atlas->AddFontXXX() call.\n - Since 1.92, font data needs to available until atlas->RemoveFont(), or more typically until a shutdown of the owning context or font atlas.\n - The fact that handling of `FontDataOwnedByAtlas = false` was broken bypassed the issue altogether.\n - 2025/11/06 (1.92.5) - BeginChild: commented out some legacy names which were obsoleted in 1.90.0 (Nov 2023), 1.90.9 (July 2024), 1.91.1 (August 2024):\n - ImGuiChildFlags_Border --> ImGuiChildFlags_Borders\n - ImGuiWindowFlags_NavFlattened --> ImGuiChildFlags_NavFlattened (moved to ImGuiChildFlags). BeginChild(name, size, 0, ImGuiWindowFlags_NavFlattened) --> BeginChild(name, size, ImGuiChildFlags_NavFlattened, 0)\n - ImGuiWindowFlags_AlwaysUseWindowPadding --> ImGuiChildFlags_AlwaysUseWindowPadding (moved to ImGuiChildFlags). BeginChild(name, size, 0, ImGuiWindowFlags_AlwaysUseWindowPadding) --> BeginChild(name, size, ImGuiChildFlags_AlwaysUseWindowPadding, 0)\n - 2025/11/06 (1.92.5) - Keys: commented out legacy names which were obsoleted in 1.89.0 (August 2022):\n - ImGuiKey_ModCtrl --> ImGuiMod_Ctrl\n - ImGuiKey_ModShift --> ImGuiMod_Shift\n - ImGuiKey_ModAlt --> ImGuiMod_Alt\n - ImGuiKey_ModSuper --> ImGuiMod_Super\n - 2025/11/06 (1.92.5) - IO: commented out legacy io.ClearInputCharacters() obsoleted in 1.89.8 (Aug 2023). Calling io.ClearInputKeys() is enough.\n - 2025/11/06 (1.92.5) - Commented out legacy SetItemAllowOverlap() obsoleted in 1.89.7: this never worked right. Use SetNextItemAllowOverlap() _before_ item instead.\n - 2025/10/14 (1.92.4) - TreeNode, Selectable, Clipper: commented out legacy names which were obsoleted in 1.89.7 (July 2023) and 1.89.9 (Sept 2023);\n - ImGuiTreeNodeFlags_AllowItemOverlap --> ImGuiTreeNodeFlags_AllowOverlap\n - ImGuiSelectableFlags_AllowItemOverlap --> ImGuiSelectableFlags_AllowOverlap\n - ImGuiListClipper::IncludeRangeByIndices() --> ImGuiListClipper::IncludeItemsByIndex()\n - 2025/09/22 (1.92.4) - Viewports: renamed io.ConfigViewportPlatformFocusSetsImGuiFocus to io.ConfigViewportsPlatformFocusSetsImGuiFocus. Was a typo in the first place. (#6299, #6462)\n - 2025/08/08 (1.92.2) - Backends: SDL_GPU3: Changed ImTextureID type from SDL_GPUTextureSamplerBinding* to SDL_GPUTexture*, which is more natural and easier for user to manage. If you need to change the current sampler, you can access the ImGui_ImplSDLGPU3_RenderState struct. (#8866, #8163, #7998, #7988)\n - 2025/07/31 (1.92.2) - Tabs: Renamed ImGuiTabBarFlags_FittingPolicyResizeDown to ImGuiTabBarFlags_FittingPolicyShrink. Kept inline redirection enum (will obsolete).\n - 2025/06/25 (1.92.0) - Layout: commented out legacy ErrorCheckUsingSetCursorPosToExtendParentBoundaries() fallback obsoleted in 1.89 (August 2022) which allowed a SetCursorPos()/SetCursorScreenPos() call WITHOUT AN ITEM\n to extend parent window/cell boundaries. Replaced with assert/tooltip that would already happens if previously using IMGUI_DISABLE_OBSOLETE_FUNCTIONS. (#5548, #4510, #3355, #1760, #1490, #4152, #150)\n - Incorrect way to make a window content size 200x200:\n Begin(...) + SetCursorScreenPos(GetCursorScreenPos() + ImVec2(200,200)) + End();\n - Correct ways to make a window content size 200x200:\n Begin(...) + SetCursorScreenPos(GetCursorScreenPos() + ImVec2(200,200)) + Dummy(ImVec2(0,0)) + End();\n Begin(...) + Dummy(ImVec2(200,200)) + End();\n - TL;DR; if the assert triggers, you can add a Dummy({0,0}) call to validate extending parent boundaries.\n - 2025/06/11 (1.92.0) - Renamed/moved ImGuiConfigFlags_DpiEnableScaleFonts -> bool io.ConfigDpiScaleFonts.\n - Renamed/moved ImGuiConfigFlags_DpiEnableScaleViewports -> bool io.ConfigDpiScaleViewports. **Neither of those flags are very useful in current code. They will be useful once we merge font changes.**\n [there was a bug on 2025/06/12: when using the old config flags names, they were not imported correctly into the new ones, fixed on 2025/09/12]\n - 2025/06/11 (1.92.0) - THIS VERSION CONTAINS THE LARGEST AMOUNT OF BREAKING CHANGES SINCE 2015! I TRIED REALLY HARD TO KEEP THEM TO A MINIMUM, REDUCE THE AMOUNT OF INTERFERENCES, BUT INEVITABLY SOME USERS WILL BE AFFECTED.\n IN ORDER TO HELP US IMPROVE THE TRANSITION PROCESS, INCL. DOCUMENTATION AND COMMENTS, PLEASE REPORT **ANY** DOUBT, CONFUSION, QUESTIONS, FEEDBACK TO: https://github.com/ocornut/imgui/issues/\n As part of the plan to reduce impact of API breaking changes, several unfinished changes/features/refactors related to font and text systems and scaling will be part of subsequent releases (1.92.1+).\n If you are updating from an old version, and expecting a massive or difficult update, consider first updating to 1.91.9 to reduce the amount of changes.\n - Hard to read? Refer to 'docs/Changelog.txt' for a less compact and more complete version of this!\n - Fonts: **IMPORTANT**: if your app was solving the OSX/iOS Retina screen specific logical vs display scale problem by setting io.DisplayFramebufferScale (e.g. to 2.0f) + setting io.FontGlobalScale (e.g. to 1.0f/2.0f) + loading fonts at scaled sizes (e.g. size X * 2.0f):\n This WILL NOT map correctly to the new system! Because font will rasterize as requested size.\n - With a legacy backend (< 1.92): Instead of setting io.FontGlobalScale = 1.0f/N -> set ImFontCfg::RasterizerDensity = N. This already worked before, but is now pretty much required.\n - With a new backend (1.92+): This should be all automatic. FramebufferScale is automatically used to set current font RasterizerDensity. FramebufferScale is a per-viewport property provided by backend through the Platform_GetWindowFramebufferScale() handler in 'docking' branch.\n - Fonts: **IMPORTANT** on Font Sizing: Before 1.92, fonts were of a single size. They can now be dynamically sized.\n - PushFont() API now has a REQUIRED size parameter.\n - Before 1.92: PushFont() always used font \"default\" size specified in AddFont() call. It is equivalent to calling PushFont(font, font->LegacySize).\n - Since 1.92: PushFont(font, 0.0f) preserve the current font size which is a shared value.\n - To use old behavior: use 'ImGui::PushFont(font, font->LegacySize)' at call site.\n - Kept inline single parameter function. Will obsolete.\n - Fonts: **IMPORTANT** on Font Merging:\n - When searching for a glyph in multiple merged fonts: we search for the FIRST font source which contains the desired glyph.\n Because the user doesn't need to provide glyph ranges any more, it is possible that a glyph that you expected to fetch from a secondary/merged icon font may be erroneously fetched from the primary font.\n - When searching for a glyph in multiple merged fonts: we now search for the FIRST font source which contains the desired glyph. This is technically a different behavior than before!\n - e.g. If you are merging fonts you may have glyphs that you expected to load from Font Source 2 which exists in Font Source 1.\n After the update and when using a new backend, those glyphs may now loaded from Font Source 1!\n - We added `ImFontConfig::GlyphExcludeRanges[]` to specify ranges to exclude from a given font source:\n // Add Font Source 1 but ignore ICON_MIN_FA..ICON_MAX_FA range\n static ImWchar exclude_ranges[] = { ICON_MIN_FA, ICON_MAX_FA, 0 };\n ImFontConfig cfg1;\n cfg1.GlyphExcludeRanges = exclude_ranges;\n io.Fonts->AddFontFromFileTTF(\"segoeui.ttf\", 0.0f, &cfg1);\n // Add Font Source 2, which expects to use the range above\n ImFontConfig cfg2;\n cfg2.MergeMode = true;\n io.Fonts->AddFontFromFileTTF(\"FontAwesome4.ttf\", 0.0f, &cfg2);\n - You can use `Metrics/Debugger->Fonts->Font->Input Glyphs Overlap Detection Tool` to see list of glyphs available in multiple font sources. This can facilitate understanding which font input is providing which glyph.\n - Fonts: **IMPORTANT** on Thread Safety:\n - A few functions such as font->CalcTextSizeA() were, by sheer luck (== accidentally) thread-safe even though we had never provided that guarantee. They are definitively not thread-safe anymore as new glyphs may be loaded.\n - Fonts: ImFont::FontSize was removed and does not make sense anymore. ImFont::LegacySize is the size passed to AddFont().\n - Fonts: Removed support for PushFont(NULL) which was a shortcut for \"default font\".\n - Fonts: Renamed/moved 'io.FontGlobalScale' to 'style.FontScaleMain'.\n - Textures: all API functions taking a 'ImTextureID' parameter are now taking a 'ImTextureRef'. Affected functions are: ImGui::Image(), ImGui::ImageWithBg(), ImGui::ImageButton(), ImDrawList::AddImage(), ImDrawList::AddImageQuad(), ImDrawList::AddImageRounded().\n - Fonts: obsoleted ImFontAtlas::GetTexDataAsRGBA32(), GetTexDataAsAlpha8(), Build(), SetTexID(), IsBuilt() functions. The new protocol for backends to handle textures doesn't need them. Kept redirection functions (will obsolete).\n - Fonts: ImFontConfig::OversampleH/OversampleV default to automatic (== 0) since v1.91.8. It is quite important you keep it automatic until we decide if we want to provide a way to express finer policy, otherwise you will likely waste texture space when using large glyphs. Note that the imgui_freetype backend doesn't use and does not need oversampling.\n - Fonts: specifying glyph ranges is now unnecessary. The value of ImFontConfig::GlyphRanges[] is only useful for legacy backends. All GetGlyphRangesXXXX() functions are now marked obsolete: GetGlyphRangesDefault(), GetGlyphRangesGreek(), GetGlyphRangesKorean(), GetGlyphRangesJapanese(), GetGlyphRangesChineseSimplifiedCommon(), GetGlyphRangesChineseFull(), GetGlyphRangesCyrillic(), GetGlyphRangesThai(), GetGlyphRangesVietnamese().\n - Fonts: removed ImFontAtlas::TexDesiredWidth to enforce a texture width. (#327)\n - Fonts: if you create and manage ImFontAtlas instances yourself (instead of relying on ImGuiContext to create one), you'll need to call ImFontAtlasUpdateNewFrame() yourself. An assert will trigger if you don't.\n - Fonts: obsolete ImGui::SetWindowFontScale() which is not useful anymore. Prefer using 'PushFont(NULL, style.FontSizeBase * factor)' or to manipulate other scaling factors.\n - Fonts: obsoleted ImFont::Scale which is not useful anymore.\n - Fonts: generally reworked Internals of ImFontAtlas and ImFont. While in theory a vast majority of users shouldn't be affected, some use cases or extensions might be. Among other things:\n - ImDrawCmd::TextureId has been changed to ImDrawCmd::TexRef.\n - ImFontAtlas::TexID has been changed to ImFontAtlas::TexRef.\n - ImFontAtlas::ConfigData[] has been renamed to ImFontAtlas::Sources[]\n - ImFont::ConfigData[], ConfigDataCount has been renamed to Sources[], SourceCount.\n - Each ImFont has a number of ImFontBaked instances corresponding to actively used sizes. ImFont::GetFontBaked(size) retrieves the one for a given size.\n - Fields moved from ImFont to ImFontBaked: IndexAdvanceX[], Glyphs[], Ascent, Descent, FindGlyph(), FindGlyphNoFallback(), GetCharAdvance().\n - Fields moved from ImFontAtlas to ImFontAtlas->Tex: ImFontAtlas::TexWidth => TexData->Width, ImFontAtlas::TexHeight => TexData->Height, ImFontAtlas::TexPixelsAlpha8/TexPixelsRGBA32 => TexData->GetPixels().\n - Widget code may use ImGui::GetFontBaked() instead of ImGui::GetFont() to access font data for current font at current font size (and you may use font->GetFontBaked(size) to access it for any other size.)\n - Fonts: (users of imgui_freetype): renamed ImFontAtlas::FontBuilderFlags to ImFontAtlas::FontLoaderFlags. Renamed ImFontConfig::FontBuilderFlags to ImFontConfig::FontLoaderFlags. Renamed ImGuiFreeTypeBuilderFlags to ImGuiFreeTypeLoaderFlags.\n If you used runtime imgui_freetype selection rather than the default IMGUI_ENABLE_FREETYPE compile-time option: Renamed/reworked ImFontBuilderIO into ImFontLoader. Renamed ImGuiFreeType::GetBuilderForFreeType() to ImGuiFreeType::GetFontLoader().\n - old: io.Fonts->FontBuilderIO = ImGuiFreeType::GetBuilderForFreeType()\n - new: io.Fonts->FontLoader = ImGuiFreeType::GetFontLoader()\n - new: io.Fonts->SetFontLoader(ImGuiFreeType::GetFontLoader()) to change dynamically at runtime [from 1.92.1]\n - Fonts: (users of custom rectangles, see #8466): Renamed AddCustomRectRegular() to AddCustomRect(). Added GetCustomRect() as a replacement for GetCustomRectByIndex() + CalcCustomRectUV().\n - The output type of GetCustomRect() is now ImFontAtlasRect, which include UV coordinates. X->x, Y->y, Width->w, Height->h.\n - old:\n const ImFontAtlasCustomRect* r = atlas->GetCustomRectByIndex(custom_rect_id);\n ImVec2 uv0, uv1;\n atlas->GetCustomRectUV(r, &uv0, &uv1);\n ImGui::Image(atlas->TexRef, ImVec2(r->w, r->h), uv0, uv1);\n - new;\n ImFontAtlasRect r;\n atlas->GetCustomRect(custom_rect_id, &r);\n ImGui::Image(atlas->TexRef, ImVec2(r.w, r.h), r.uv0, r.uv1);\n - We added a redirecting typedef but haven't attempted to magically redirect the field names, as this API is rarely used and the fix is simple.\n - Obsoleted AddCustomRectFontGlyph() as the API does not make sense for scalable fonts. Kept existing function which uses the font \"default size\" (Sources[0]->LegacySize). Added a helper AddCustomRectFontGlyphForSize() which is immediately marked obsolete, but can facilitate transitioning old code.\n - Prefer adding a font source (ImFontConfig) using a custom/procedural loader.\n - DrawList: Renamed ImDrawList::PushTextureID()/PopTextureID() to PushTexture()/PopTexture().\n - Backends: removed ImGui_ImplXXXX_CreateFontsTexture()/ImGui_ImplXXXX_DestroyFontsTexture() for all backends that had them. They should not be necessary any more.\n - 2025/05/23 (1.92.0) - Fonts: changed ImFont::CalcWordWrapPositionA() to ImFont::CalcWordWrapPosition()\n - old: const char* ImFont::CalcWordWrapPositionA(float scale, const char* text, ....);\n - new: const char* ImFont::CalcWordWrapPosition (float size, const char* text, ....);\n The leading 'float scale' parameters was changed to 'float size'. This was necessary as 'scale' is assuming standard font size which is a concept we aim to eliminate in an upcoming update. Kept inline redirection function.\n - 2025/05/15 (1.92.0) - TreeNode: renamed ImGuiTreeNodeFlags_NavLeftJumpsBackHere to ImGuiTreeNodeFlags_NavLeftJumpsToParent for clarity. Kept inline redirection enum (will obsolete).\n - 2025/05/15 (1.92.0) - Commented out PushAllowKeyboardFocus()/PopAllowKeyboardFocus() which was obsoleted in 1.89.4. Use PushItemFlag(ImGuiItemFlags_NoTabStop, !tab_stop)/PopItemFlag() instead. (#3092)\n - 2025/05/15 (1.92.0) - Commented out ImGuiListClipper::ForceDisplayRangeByIndices() which was obsoleted in 1.89.6. Use ImGuiListClipper::IncludeItemsByIndex() instead.\n - 2025/03/05 (1.91.9) - BeginMenu(): Internals: reworked mangling of menu windows to use \"###Menu_00\" etc. instead of \"##Menu_00\", allowing them to also store the menu name before it. This shouldn't affect code unless directly accessing menu window from their mangled name.\n - 2025/04/16 (1.91.9) - Internals: RenderTextEllipsis() function removed the 'float clip_max_x' parameter directly preceding 'float ellipsis_max_x'. Values were identical for a vast majority of users. (#8387)\n - 2025/02/27 (1.91.9) - Image(): removed 'tint_col' and 'border_col' parameter from Image() function. Added ImageWithBg() replacement. (#8131, #8238)\n - old: void Image (ImTextureID tex_id, ImVec2 image_size, ImVec2 uv0 = (0,0), ImVec2 uv1 = (1,1), ImVec4 tint_col = (1,1,1,1), ImVec4 border_col = (0,0,0,0));\n - new: void Image (ImTextureID tex_id, ImVec2 image_size, ImVec2 uv0 = (0,0), ImVec2 uv1 = (1,1));\n - new: void ImageWithBg(ImTextureID tex_id, ImVec2 image_size, ImVec2 uv0 = (0,0), ImVec2 uv1 = (1,1), ImVec4 bg_col = (0,0,0,0), ImVec4 tint_col = (1,1,1,1));\n - TL;DR: 'border_col' had misleading side-effect on layout, 'bg_col' was missing, parameter order couldn't be consistent with ImageButton().\n - new behavior always use ImGuiCol_Border color + style.ImageBorderSize / ImGuiStyleVar_ImageBorderSize.\n - old behavior altered border size (and therefore layout) based on border color's alpha, which caused variety of problems + old behavior a fixed 1.0f for border size which was not tweakable.\n - kept legacy signature (will obsolete), which mimics the old behavior, but uses Max(1.0f, style.ImageBorderSize) when border_col is specified.\n - added ImageWithBg() function which has both 'bg_col' (which was missing) and 'tint_col'. It was impossible to add 'bg_col' to Image() with a parameter order consistent with other functions, so we decided to remove 'tint_col' and introduce ImageWithBg().\n - 2025/02/25 (1.91.9) - internals: fonts: ImFontAtlas::ConfigData[] has been renamed to ImFontAtlas::Sources[]. ImFont::ConfigData[], ConfigDataCount has been renamed to Sources[], SourcesCount.\n - 2025/02/06 (1.91.9) - renamed ImFontConfig::GlyphExtraSpacing.x to ImFontConfig::GlyphExtraAdvanceX.\n - 2025/01/22 (1.91.8) - removed ImGuiColorEditFlags_AlphaPreview (made value 0): it is now the default behavior.\n prior to 1.91.8: alpha was made opaque in the preview by default _unless_ using ImGuiColorEditFlags_AlphaPreview. We now display the preview as transparent by default. You can use ImGuiColorEditFlags_AlphaOpaque to use old behavior.\n the new flags (ImGuiColorEditFlags_AlphaOpaque, ImGuiColorEditFlags_AlphaNoBg + existing ImGuiColorEditFlags_AlphaPreviewHalf) may be combined better and allow finer controls:\n - 2025/01/14 (1.91.7) - renamed ImGuiTreeNodeFlags_SpanTextWidth to ImGuiTreeNodeFlags_SpanLabelWidth for consistency with other names. Kept redirection enum (will obsolete). (#6937)\n - 2024/11/27 (1.91.6) - changed CRC32 table from CRC32-adler to CRC32c polynomial in order to be compatible with the result of SSE 4.2 instructions.\n As a result, old .ini data may be partially lost (docking and tables information particularly).\n Because some users have crafted and storing .ini data as a way to workaround limitations of the docking API, we are providing a '#define IMGUI_USE_LEGACY_CRC32_ADLER' compile-time option to keep using old CRC32 tables if you cannot afford invalidating old .ini data.\n - 2024/11/06 (1.91.5) - commented/obsoleted out pre-1.87 IO system (equivalent to using IMGUI_DISABLE_OBSOLETE_KEYIO or IMGUI_DISABLE_OBSOLETE_FUNCTIONS before)\n - io.KeyMap[] and io.KeysDown[] are removed (obsoleted February 2022).\n - io.NavInputs[] and ImGuiNavInput are removed (obsoleted July 2022).\n - GetKeyIndex() is removed (obsoleted March 2022). The indirection is now unnecessary.\n - pre-1.87 backends are not supported:\n - backends need to call io.AddKeyEvent(), io.AddMouseEvent() instead of writing to io.KeysDown[], io.MouseDown[] fields.\n - backends need to call io.AddKeyAnalogEvent() for gamepad values instead of writing to io.NavInputs[] fields.\n - for more reference:\n - read 1.87 and 1.88 part of this section or read Changelog for 1.87 and 1.88.\n - read https://github.com/ocornut/imgui/issues/4921\n - if you have trouble updating a very old codebase using legacy backend-specific key codes: consider updating to 1.91.4 first, then #define IMGUI_DISABLE_OBSOLETE_KEYIO, then update to latest.\n - obsoleted ImGuiKey_COUNT (it is unusually error-prone/misleading since valid keys don't start at 0). probably use ImGuiKey_NamedKey_BEGIN/ImGuiKey_NamedKey_END?\n - fonts: removed const qualifiers from most font functions in prevision for upcoming font improvements.\n - 2024/10/18 (1.91.4) - renamed ImGuiCol_NavHighlight to ImGuiCol_NavCursor (for consistency with newly exposed and reworked features). Kept inline redirection enum (will obsolete).\n - 2024/10/14 (1.91.4) - moved ImGuiConfigFlags_NavEnableSetMousePos to standalone io.ConfigNavMoveSetMousePos bool.\n moved ImGuiConfigFlags_NavNoCaptureKeyboard to standalone io.ConfigNavCaptureKeyboard bool (note the inverted value!).\n kept legacy names (will obsolete) + code that copies settings once the first time. Dynamically changing the old value won't work. Switch to using the new value!\n - 2024/10/10 (1.91.4) - the typedef for ImTextureID now defaults to ImU64 instead of void*. (#1641)\n this removes the requirement to redefine it for backends which are e.g. storing descriptor sets or other 64-bits structures when building on 32-bits archs. It therefore simplify various building scripts/helpers.\n you may have compile-time issues if you were casting to 'void*' instead of 'ImTextureID' when passing your types to functions taking ImTextureID values, e.g. ImGui::Image().\n in doubt it is almost always better to do an intermediate intptr_t cast, since it allows casting any pointer/integer type without warning:\n - May warn: ImGui::Image((void*)MyTextureData, ...);\n - May warn: ImGui::Image((void*)(intptr_t)MyTextureData, ...);\n - Won't warn: ImGui::Image((ImTextureID)(intptr_t)MyTextureData, ...);\n - note that you can always define ImTextureID to be your own high-level structures (with dedicated constructors) if you like.\n - 2024/10/03 (1.91.3) - drags: treat v_min==v_max as a valid clamping range when != 0.0f. Zero is a still special value due to legacy reasons, unless using ImGuiSliderFlags_ClampZeroRange. (#7968, #3361, #76)\n - drags: extended behavior of ImGuiSliderFlags_AlwaysClamp to include _ClampZeroRange. It considers v_min==v_max==0.0f as a valid clamping range (aka edits not allowed).\n although unlikely, it you wish to only clamp on text input but want v_min==v_max==0.0f to mean unclamped drags, you can use _ClampOnInput instead of _AlwaysClamp. (#7968, #3361, #76)\n - 2024/09/10 (1.91.2) - internals: using multiple overlaid ButtonBehavior() with same ID will now have io.ConfigDebugHighlightIdConflicts=true feature emit a warning. (#8030)\n it was one of the rare case where using same ID is legal. workarounds: (1) use single ButtonBehavior() call with multiple _MouseButton flags, or (2) surround the calls with PushItemFlag(ImGuiItemFlags_AllowDuplicateId, true); ... PopItemFlag()\n - 2024/08/23 (1.91.1) - renamed ImGuiChildFlags_Border to ImGuiChildFlags_Borders for consistency. kept inline redirection flag.\n - 2024/08/22 (1.91.1) - moved some functions from ImGuiIO to ImGuiPlatformIO structure:\n - io.GetClipboardTextFn -> platform_io.Platform_GetClipboardTextFn + changed 'void* user_data' to 'ImGuiContext* ctx'. Pull your user data from platform_io.ClipboardUserData.\n - io.SetClipboardTextFn -> platform_io.Platform_SetClipboardTextFn + same as above line.\n - io.PlatformOpenInShellFn -> platform_io.Platform_OpenInShellFn (#7660)\n - io.PlatformSetImeDataFn -> platform_io.Platform_SetImeDataFn\n - io.PlatformLocaleDecimalPoint -> platform_io.Platform_LocaleDecimalPoint (#7389, #6719, #2278)\n - access those via GetPlatformIO() instead of GetIO().\n some were introduced very recently and often automatically setup by core library and backends, so for those we are exceptionally not maintaining a legacy redirection symbol.\n - commented the old ImageButton() signature obsoleted in 1.89 (~August 2022). As a reminder:\n - old ImageButton() before 1.89 used ImTextureId as item id (created issue with e.g. multiple buttons in same scope, transient texture id values, opaque computation of ID)\n - new ImageButton() since 1.89 requires an explicit 'const char* str_id'\n - old ImageButton() before 1.89 had frame_padding' override argument.\n - new ImageButton() since 1.89 always use style.FramePadding, which you can freely override with PushStyleVar()/PopStyleVar().\n - 2024/07/25 (1.91.0) - obsoleted GetContentRegionMax(), GetWindowContentRegionMin() and GetWindowContentRegionMax(). (see #7838 on GitHub for more info)\n you should never need those functions. you can do everything with GetCursorScreenPos() and GetContentRegionAvail() in a more simple way.\n - instead of: GetWindowContentRegionMax().x - GetCursorPos().x\n - you can use: GetContentRegionAvail().x\n - instead of: GetWindowContentRegionMax().x + GetWindowPos().x\n - you can use: GetCursorScreenPos().x + GetContentRegionAvail().x // when called from left edge of window\n - instead of: GetContentRegionMax()\n - you can use: GetContentRegionAvail() + GetCursorScreenPos() - GetWindowPos() // right edge in local coordinates\n - instead of: GetWindowContentRegionMax().x - GetWindowContentRegionMin().x\n - you can use: GetContentRegionAvail() // when called from left edge of window\n - 2024/07/15 (1.91.0) - renamed ImGuiSelectableFlags_DontClosePopups to ImGuiSelectableFlags_NoAutoClosePopups. (#1379, #1468, #2200, #4936, #5216, #7302, #7573)\n (internals: also renamed ImGuiItemFlags_SelectableDontClosePopup into ImGuiItemFlags_AutoClosePopups with inverted behaviors)\n - 2024/07/15 (1.91.0) - obsoleted PushButtonRepeat()/PopButtonRepeat() in favor of using new PushItemFlag(ImGuiItemFlags_ButtonRepeat, ...)/PopItemFlag().\n - 2024/07/02 (1.91.0) - commented out obsolete ImGuiModFlags (renamed to ImGuiKeyChord in 1.89). (#4921, #456)\n - commented out obsolete ImGuiModFlags_XXX values (renamed to ImGuiMod_XXX in 1.89). (#4921, #456)\n - ImGuiModFlags_Ctrl -> ImGuiMod_Ctrl, ImGuiModFlags_Shift -> ImGuiMod_Shift etc.\n - 2024/07/02 (1.91.0) - IO, IME: renamed platform IME hook and added explicit context for consistency and future-proofness.\n - old: io.SetPlatformImeDataFn(ImGuiViewport* viewport, ImGuiPlatformImeData* data);\n - new: io.PlatformSetImeDataFn(ImGuiContext* ctx, ImGuiViewport* viewport, ImGuiPlatformImeData* data);\n - 2024/06/21 (1.90.9) - BeginChild: added ImGuiChildFlags_NavFlattened as a replacement for the window flag ImGuiWindowFlags_NavFlattened: the feature only ever made sense for BeginChild() anyhow.\n - old: BeginChild(\"Name\", size, 0, ImGuiWindowFlags_NavFlattened);\n - new: BeginChild(\"Name\", size, ImGuiChildFlags_NavFlattened, 0);\n - 2024/06/21 (1.90.9) - io: ClearInputKeys() (first exposed in 1.89.8) doesn't clear mouse data, newly added ClearInputMouse() does.\n - 2024/06/20 (1.90.9) - renamed ImGuiDragDropFlags_SourceAutoExpirePayload to ImGuiDragDropFlags_PayloadAutoExpire.\n - 2024/06/18 (1.90.9) - style: renamed ImGuiCol_TabActive -> ImGuiCol_TabSelected, ImGuiCol_TabUnfocused -> ImGuiCol_TabDimmed, ImGuiCol_TabUnfocusedActive -> ImGuiCol_TabDimmedSelected.\n - 2024/06/10 (1.90.9) - removed old nested structure: renaming ImGuiStorage::ImGuiStoragePair type to ImGuiStoragePair (simpler for many languages).\n - 2024/06/06 (1.90.8) - reordered ImGuiInputTextFlags values. This should not be breaking unless you are using generated headers that have values not matching the main library.\n - 2024/06/06 (1.90.8) - removed 'ImGuiButtonFlags_MouseButtonDefault_ = ImGuiButtonFlags_MouseButtonLeft', was mostly unused and misleading.\n - 2024/05/27 (1.90.7) - commented out obsolete symbols marked obsolete in 1.88 (May 2022):\n - old: CaptureKeyboardFromApp(bool)\n - new: SetNextFrameWantCaptureKeyboard(bool)\n - old: CaptureMouseFromApp(bool)\n - new: SetNextFrameWantCaptureMouse(bool)\n - 2024/05/22 (1.90.7) - inputs (internals): renamed ImGuiKeyOwner_None to ImGuiKeyOwner_NoOwner, to make use more explicit and reduce confusion with the default it is a non-zero value and cannot be the default value (never made public, but disclosing as I expect a few users caught on owner-aware inputs).\n - inputs (internals): renamed ImGuiInputFlags_RouteGlobalLow -> ImGuiInputFlags_RouteGlobal, ImGuiInputFlags_RouteGlobal -> ImGuiInputFlags_RouteGlobalOverFocused, ImGuiInputFlags_RouteGlobalHigh -> ImGuiInputFlags_RouteGlobalHighest.\n - inputs (internals): Shortcut(), SetShortcutRouting(): swapped last two parameters order in function signatures:\n - old: Shortcut(ImGuiKeyChord key_chord, ImGuiID owner_id = 0, ImGuiInputFlags flags = 0);\n - new: Shortcut(ImGuiKeyChord key_chord, ImGuiInputFlags flags = 0, ImGuiID owner_id = 0);\n - inputs (internals): owner-aware versions of IsKeyPressed(), IsKeyChordPressed(), IsMouseClicked(): swapped last two parameters order in function signatures.\n - old: IsKeyPressed(ImGuiKey key, ImGuiID owner_id, ImGuiInputFlags flags = 0);\n - new: IsKeyPressed(ImGuiKey key, ImGuiInputFlags flags, ImGuiID owner_id = 0);\n - old: IsMouseClicked(ImGuiMouseButton button, ImGuiID owner_id, ImGuiInputFlags flags = 0);\n - new: IsMouseClicked(ImGuiMouseButton button, ImGuiInputFlags flags, ImGuiID owner_id = 0);\n for various reasons those changes makes sense. They are being made because making some of those API public.\n only past users of imgui_internal.h with the extra parameters will be affected. Added asserts for valid flags in various functions to detect _some_ misuses, BUT NOT ALL.\n - 2024/05/21 (1.90.7) - docking: changed signature of DockSpaceOverViewport() to add explicit dockspace id if desired. pass 0 to use old behavior. (#7611)\n - old: DockSpaceOverViewport(const ImGuiViewport* viewport = NULL, ImGuiDockNodeFlags flags = 0, ...);\n - new: DockSpaceOverViewport(ImGuiID dockspace_id = 0, const ImGuiViewport* viewport = NULL, ImGuiDockNodeFlags flags = 0, ...);\n - 2024/05/16 (1.90.7) - inputs: on macOS X, Cmd and Ctrl keys are now automatically swapped by io.AddKeyEvent() as this naturally align with how macOS X uses those keys.\n - it shouldn't really affect you unless you had custom shortcut swapping in place for macOS X apps.\n - removed ImGuiMod_Shortcut which was previously dynamically remapping to Ctrl or Cmd/Super. It is now unnecessary to specific cross-platform idiomatic shortcuts. (#2343, #4084, #5923, #456)\n - 2024/05/14 (1.90.7) - backends: SDL_Renderer2 and SDL_Renderer3 backend now take a SDL_Renderer* in their RenderDrawData() functions.\n - 2024/04/18 (1.90.6) - TreeNode: Fixed a layout inconsistency when using an empty/hidden label followed by a SameLine() call. (#7505, #282)\n - old: TreeNode(\"##Hidden\"); SameLine(); Text(\"Hello\"); // <-- This was actually incorrect! BUT appeared to look ok with the default style where ItemSpacing.x == FramePadding.x * 2 (it didn't look aligned otherwise).\n - new: TreeNode(\"##Hidden\"); SameLine(0, 0); Text(\"Hello\"); // <-- This is correct for all styles values.\n with the fix, IF you were successfully using TreeNode(\"\")+SameLine(); you will now have extra spacing between your TreeNode and the following item.\n You'll need to change the SameLine() call to SameLine(0,0) to remove this extraneous spacing. This seemed like the more sensible fix that's not making things less consistent.\n (Note: when using this idiom you are likely to also use ImGuiTreeNodeFlags_SpanAvailWidth).\n - 2024/03/18 (1.90.5) - merged the radius_x/radius_y parameters in ImDrawList::AddEllipse(), AddEllipseFilled() and PathEllipticalArcTo() into a single ImVec2 parameter. Exceptionally, because those functions were added in 1.90, we are not adding inline redirection functions. The transition is easy and should affect few users. (#2743, #7417)\n - 2024/03/08 (1.90.5) - inputs: more formally obsoleted GetKeyIndex() when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is set. It has been unnecessary and a no-op since 1.87 (it returns the same value as passed when used with a 1.87+ backend using io.AddKeyEvent() function). (#4921)\n - IsKeyPressed(GetKeyIndex(ImGuiKey_XXX)) -> use IsKeyPressed(ImGuiKey_XXX)\n - 2024/01/15 (1.90.2) - commented out obsolete ImGuiIO::ImeWindowHandle marked obsolete in 1.87, favor of writing to 'void* ImGuiViewport::PlatformHandleRaw'.\n - 2023/12/19 (1.90.1) - commented out obsolete ImGuiKey_KeyPadEnter redirection to ImGuiKey_KeypadEnter.\n - 2023/11/06 (1.90.1) - removed CalcListClipping() marked obsolete in 1.86. Prefer using ImGuiListClipper which can return non-contiguous ranges.\n - 2023/11/05 (1.90.1) - imgui_freetype: commented out ImGuiFreeType::BuildFontAtlas() obsoleted in 1.81. prefer using #define IMGUI_ENABLE_FREETYPE or see commented code for manual calls.\n - 2023/11/05 (1.90.1) - internals,columns: commented out legacy ImGuiColumnsFlags_XXX symbols redirecting to ImGuiOldColumnsFlags_XXX, obsoleted from imgui_internal.h in 1.80.\n - 2023/11/09 (1.90.0) - removed IM_OFFSETOF() macro in favor of using offsetof() available in C++11. Kept redirection define (will obsolete).\n - 2023/11/07 (1.90.0) - removed BeginChildFrame()/EndChildFrame() in favor of using BeginChild() with the ImGuiChildFlags_FrameStyle flag. kept inline redirection function (will obsolete).\n those functions were merely PushStyle/PopStyle helpers, the removal isn't so much motivated by needing to add the feature in BeginChild(), but by the necessity to avoid BeginChildFrame() signature mismatching BeginChild() signature and features.\n - 2023/11/02 (1.90.0) - BeginChild: upgraded 'bool border = true' parameter to 'ImGuiChildFlags flags' type, added ImGuiChildFlags_Border equivalent. As with our prior \"bool-to-flags\" API updates, the ImGuiChildFlags_Border value is guaranteed to be == true forever to ensure a smoother transition, meaning all existing calls will still work.\n - old: BeginChild(\"Name\", size, true)\n - new: BeginChild(\"Name\", size, ImGuiChildFlags_Border)\n - old: BeginChild(\"Name\", size, false)\n - new: BeginChild(\"Name\", size) or BeginChild(\"Name\", 0) or BeginChild(\"Name\", size, ImGuiChildFlags_None)\n **AMEND FROM THE FUTURE: from 1.91.1, 'ImGuiChildFlags_Border' is called 'ImGuiChildFlags_Borders'**\n - 2023/11/02 (1.90.0) - BeginChild: added child-flag ImGuiChildFlags_AlwaysUseWindowPadding as a replacement for the window-flag ImGuiWindowFlags_AlwaysUseWindowPadding: the feature only ever made sense for BeginChild() anyhow.\n - old: BeginChild(\"Name\", size, 0, ImGuiWindowFlags_AlwaysUseWindowPadding);\n - new: BeginChild(\"Name\", size, ImGuiChildFlags_AlwaysUseWindowPadding, 0);\n - 2023/09/27 (1.90.0) - io: removed io.MetricsActiveAllocations introduced in 1.63. Same as 'g.DebugMemAllocCount - g.DebugMemFreeCount' (still displayed in Metrics, unlikely to be accessed by end-user).\n - 2023/09/26 (1.90.0) - debug tools: Renamed ShowStackToolWindow() (\"Stack Tool\") to ShowIDStackToolWindow() (\"ID Stack Tool\"), as earlier name was misleading. Kept inline redirection function. (#4631)\n - 2023/09/15 (1.90.0) - ListBox, Combo: changed signature of \"name getter\" callback in old one-liner ListBox()/Combo() apis. kept inline redirection function (will obsolete).\n - old: bool Combo(const char* label, int* current_item, bool (*getter)(void* user_data, int idx, const char** out_text), ...)\n - new: bool Combo(const char* label, int* current_item, const char* (*getter)(void* user_data, int idx), ...);\n - old: bool ListBox(const char* label, int* current_item, bool (*getting)(void* user_data, int idx, const char** out_text), ...);\n - new: bool ListBox(const char* label, int* current_item, const char* (*getter)(void* user_data, int idx), ...);\n - 2023/09/08 (1.90.0) - commented out obsolete redirecting functions:\n - GetWindowContentRegionWidth() -> use GetWindowContentRegionMax().x - GetWindowContentRegionMin().x. Consider that generally 'GetContentRegionAvail().x' is more useful.\n - ImDrawCornerFlags_XXX -> use ImDrawFlags_RoundCornersXXX flags. Read 1.82 Changelog for details + grep commented names in sources.\n - commented out runtime support for hardcoded ~0 or 0x01..0x0F rounding flags values for AddRect()/AddRectFilled()/PathRect()/AddImageRounded() -> use ImDrawFlags_RoundCornersXXX flags. Read 1.82 Changelog for details\n - 2023/08/25 (1.89.9) - clipper: Renamed IncludeRangeByIndices() (also called ForceDisplayRangeByIndices() before 1.89.6) to IncludeItemsByIndex(). Kept inline redirection function. Sorry!\n - 2023/07/12 (1.89.8) - ImDrawData: CmdLists now owned, changed from ImDrawList** to ImVector. Majority of users shouldn't be affected, but you cannot compare to NULL nor reassign manually anymore. Instead use AddDrawList(). (#6406, #4879, #1878)\n - 2023/06/28 (1.89.7) - overlapping items: obsoleted 'SetItemAllowOverlap()' (called after item) in favor of calling 'SetNextItemAllowOverlap()' (called before item). 'SetItemAllowOverlap()' didn't and couldn't work reliably since 1.89 (2022-11-15).\n - 2023/06/28 (1.89.7) - overlapping items: renamed 'ImGuiTreeNodeFlags_AllowItemOverlap' to 'ImGuiTreeNodeFlags_AllowOverlap', 'ImGuiSelectableFlags_AllowItemOverlap' to 'ImGuiSelectableFlags_AllowOverlap'. Kept redirecting enums (will obsolete).\n - 2023/06/28 (1.89.7) - overlapping items: IsItemHovered() now by default return false when querying an item using AllowOverlap mode which is being overlapped. Use ImGuiHoveredFlags_AllowWhenOverlappedByItem to revert to old behavior.\n - 2023/06/28 (1.89.7) - overlapping items: Selectable and TreeNode don't allow overlap when active so overlapping widgets won't appear as hovered. While this fixes a common small visual issue, it also means that calling IsItemHovered() after a non-reactive elements - e.g. Text() - overlapping an active one may fail if you don't use IsItemHovered(ImGuiHoveredFlags_AllowWhenBlockedByActiveItem). (#6610)\n - 2023/06/20 (1.89.7) - moved io.HoverDelayShort/io.HoverDelayNormal to style.HoverDelayShort/style.HoverDelayNormal. As the fields were added in 1.89 and expected to be left unchanged by most users, or only tweaked once during app initialization, we are exceptionally accepting the breakage.\n - 2023/05/30 (1.89.6) - backends: renamed \"imgui_impl_sdlrenderer.cpp\" to \"imgui_impl_sdlrenderer2.cpp\" and \"imgui_impl_sdlrenderer.h\" to \"imgui_impl_sdlrenderer2.h\". This is in prevision for the future release of SDL3.\n - 2023/05/22 (1.89.6) - listbox: commented out obsolete/redirecting functions that were marked obsolete more than two years ago:\n - ListBoxHeader() -> use BeginListBox() (note how two variants of ListBoxHeader() existed. Check commented versions in imgui.h for reference)\n - ListBoxFooter() -> use EndListBox()\n - 2023/05/15 (1.89.6) - clipper: commented out obsolete redirection constructor 'ImGuiListClipper(int items_count, float items_height = -1.0f)' that was marked obsolete in 1.79. Use default constructor + clipper.Begin().\n - 2023/05/15 (1.89.6) - clipper: renamed ImGuiListClipper::ForceDisplayRangeByIndices() to ImGuiListClipper::IncludeRangeByIndices().\n - 2023/03/14 (1.89.4) - commented out redirecting enums/functions names that were marked obsolete two years ago:\n - ImGuiSliderFlags_ClampOnInput -> use ImGuiSliderFlags_AlwaysClamp\n - ImGuiInputTextFlags_AlwaysInsertMode -> use ImGuiInputTextFlags_AlwaysOverwrite\n - ImDrawList::AddBezierCurve() -> use ImDrawList::AddBezierCubic()\n - ImDrawList::PathBezierCurveTo() -> use ImDrawList::PathBezierCubicCurveTo()\n - 2023/03/09 (1.89.4) - renamed PushAllowKeyboardFocus()/PopAllowKeyboardFocus() to PushTabStop()/PopTabStop(). Kept inline redirection functions (will obsolete).\n - 2023/03/09 (1.89.4) - tooltips: Added 'bool' return value to BeginTooltip() for API consistency. Please only submit contents and call EndTooltip() if BeginTooltip() returns true. In reality the function will _currently_ always return true, but further changes down the line may change this, best to clarify API sooner.\n - 2023/02/15 (1.89.4) - moved the optional \"courtesy maths operators\" implementation from imgui_internal.h in imgui.h.\n Even though we encourage using your own maths types and operators by setting up IM_VEC2_CLASS_EXTRA,\n it has been frequently requested by people to use our own. We had an opt-in define which was\n previously fulfilled in imgui_internal.h. It is now fulfilled in imgui.h. (#6164)\n - OK: #define IMGUI_DEFINE_MATH_OPERATORS / #include \"imgui.h\" / #include \"imgui_internal.h\"\n - Error: #include \"imgui.h\" / #define IMGUI_DEFINE_MATH_OPERATORS / #include \"imgui_internal.h\"\n - 2023/02/07 (1.89.3) - backends: renamed \"imgui_impl_sdl.cpp\" to \"imgui_impl_sdl2.cpp\" and \"imgui_impl_sdl.h\" to \"imgui_impl_sdl2.h\". (#6146) This is in prevision for the future release of SDL3.\n - 2022/10/26 (1.89) - commented out redirecting OpenPopupContextItem() which was briefly the name of OpenPopupOnItemClick() from 1.77 to 1.79.\n - 2022/10/12 (1.89) - removed runtime patching of invalid \"%f\"/\"%0.f\" format strings for DragInt()/SliderInt(). This was obsoleted in 1.61 (May 2018). See 1.61 changelog for details.\n - 2022/09/26 (1.89) - renamed and merged keyboard modifiers key enums and flags into a same set. Kept inline redirection enums (will obsolete).\n - ImGuiKey_ModCtrl and ImGuiModFlags_Ctrl -> ImGuiMod_Ctrl\n - ImGuiKey_ModShift and ImGuiModFlags_Shift -> ImGuiMod_Shift\n - ImGuiKey_ModAlt and ImGuiModFlags_Alt -> ImGuiMod_Alt\n - ImGuiKey_ModSuper and ImGuiModFlags_Super -> ImGuiMod_Super\n the ImGuiKey_ModXXX were introduced in 1.87 and mostly used by backends.\n the ImGuiModFlags_XXX have been exposed in imgui.h but not really used by any public api only by third-party extensions.\n exceptionally commenting out the older ImGuiKeyModFlags_XXX names ahead of obsolescence schedule to reduce confusion and because they were not meant to be used anyway.\n - 2022/09/20 (1.89) - ImGuiKey is now a typed enum, allowing ImGuiKey_XXX symbols to be named in debuggers.\n this will require uses of legacy backend-dependent indices to be casted, e.g.\n - with imgui_impl_glfw: IsKeyPressed(GLFW_KEY_A) -> IsKeyPressed((ImGuiKey)GLFW_KEY_A);\n - with imgui_impl_win32: IsKeyPressed('A') -> IsKeyPressed((ImGuiKey)'A')\n - etc. However if you are upgrading code you might well use the better, backend-agnostic IsKeyPressed(ImGuiKey_A) now!\n - 2022/09/12 (1.89) - removed the bizarre legacy default argument for 'TreePush(const void* ptr = NULL)', always pass a pointer value explicitly. NULL/nullptr is ok but require cast, e.g. TreePush((void*)nullptr);\n - 2022/09/05 (1.89) - commented out redirecting functions/enums names that were marked obsolete in 1.77 and 1.78 (June 2020):\n - DragScalar(), DragScalarN(), DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(): For old signatures ending with (..., const char* format, float power = 1.0f) -> use (..., format ImGuiSliderFlags_Logarithmic) if power != 1.0f.\n - SliderScalar(), SliderScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(): For old signatures ending with (..., const char* format, float power = 1.0f) -> use (..., format ImGuiSliderFlags_Logarithmic) if power != 1.0f.\n - BeginPopupContextWindow(const char*, ImGuiMouseButton, bool) -> use BeginPopupContextWindow(const char*, ImGuiPopupFlags)\n - 2022/09/02 (1.89) - obsoleted using SetCursorPos()/SetCursorScreenPos() to extend parent window/cell boundaries.\n this relates to when moving the cursor position beyond current boundaries WITHOUT submitting an item.\n - previously this would make the window content size ~200x200:\n Begin(...) + SetCursorScreenPos(GetCursorScreenPos() + ImVec2(200,200)) + End();\n - instead, please submit an item:\n Begin(...) + SetCursorScreenPos(GetCursorScreenPos() + ImVec2(200,200)) + Dummy(ImVec2(0,0)) + End();\n - alternative:\n Begin(...) + Dummy(ImVec2(200,200)) + End();\n - content size is now only extended when submitting an item!\n - with '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' this will now be detected and assert.\n - without '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' this will silently be fixed until we obsolete it.\n - 2022/08/03 (1.89) - changed signature of ImageButton() function. Kept redirection function (will obsolete).\n - added 'const char* str_id' parameter + removed 'int frame_padding = -1' parameter.\n - old signature: bool ImageButton(ImTextureID tex_id, ImVec2 size, ImVec2 uv0 = ImVec2(0,0), ImVec2 uv1 = ImVec2(1,1), int frame_padding = -1, ImVec4 bg_col = ImVec4(0,0,0,0), ImVec4 tint_col = ImVec4(1,1,1,1));\n - used the ImTextureID value to create an ID. This was inconsistent with other functions, led to ID conflicts, and caused problems with engines using transient ImTextureID values.\n - had a FramePadding override which was inconsistent with other functions and made the already-long signature even longer.\n - new signature: bool ImageButton(const char* str_id, ImTextureID tex_id, ImVec2 size, ImVec2 uv0 = ImVec2(0,0), ImVec2 uv1 = ImVec2(1,1), ImVec4 bg_col = ImVec4(0,0,0,0), ImVec4 tint_col = ImVec4(1,1,1,1));\n - requires an explicit identifier. You may still use e.g. PushID() calls and then pass an empty identifier.\n - always uses style.FramePadding for padding, to be consistent with other buttons. You may use PushStyleVar() to alter this.\n - 2022/07/08 (1.89) - inputs: removed io.NavInputs[] and ImGuiNavInput enum (following 1.87 changes).\n - Official backends from 1.87+ -> no issue.\n - Official backends from 1.60 to 1.86 -> will build and convert gamepad inputs, unless IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Need updating!\n - Custom backends not writing to io.NavInputs[] -> no issue.\n - Custom backends writing to io.NavInputs[] -> will build and convert gamepad inputs, unless IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Need fixing!\n - TL;DR: Backends should call io.AddKeyEvent()/io.AddKeyAnalogEvent() with ImGuiKey_GamepadXXX values instead of filling io.NavInput[].\n - 2022/06/15 (1.88) - renamed IMGUI_DISABLE_METRICS_WINDOW to IMGUI_DISABLE_DEBUG_TOOLS for correctness. kept support for old define (will obsolete).\n - 2022/05/03 (1.88) - backends: osx: removed ImGui_ImplOSX_HandleEvent() from backend API in favor of backend automatically handling event capture. All ImGui_ImplOSX_HandleEvent() calls should be removed as they are now unnecessary.\n - 2022/04/05 (1.88) - inputs: renamed ImGuiKeyModFlags to ImGuiModFlags. Kept inline redirection enums (will obsolete). This was never used in public API functions but technically present in imgui.h and ImGuiIO.\n - 2022/01/20 (1.87) - inputs: reworded gamepad IO.\n - Backend writing to io.NavInputs[] -> backend should call io.AddKeyEvent()/io.AddKeyAnalogEvent() with ImGuiKey_GamepadXXX values.\n - 2022/01/19 (1.87) - sliders, drags: removed support for legacy arithmetic operators (+,+-,*,/) when inputting text. This doesn't break any api/code but a feature that used to be accessible by end-users (which seemingly no one used).\n - 2022/01/17 (1.87) - inputs: reworked mouse IO.\n - Backend writing to io.MousePos -> backend should call io.AddMousePosEvent()\n - Backend writing to io.MouseDown[] -> backend should call io.AddMouseButtonEvent()\n - Backend writing to io.MouseWheel -> backend should call io.AddMouseWheelEvent()\n - Backend writing to io.MouseHoveredViewport -> backend should call io.AddMouseViewportEvent() [Docking branch w/ multi-viewports only]\n note: for all calls to IO new functions, the Dear ImGui context should be bound/current.\n read https://github.com/ocornut/imgui/issues/4921 for details.\n - 2022/01/10 (1.87) - inputs: reworked keyboard IO. Removed io.KeyMap[], io.KeysDown[] in favor of calling io.AddKeyEvent(), ImGui::IsKeyDown(). Removed GetKeyIndex(), now unnecessary. All IsKeyXXX() functions now take ImGuiKey values. All features are still functional until IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Read Changelog and Release Notes for details.\n - IsKeyPressed(MY_NATIVE_KEY_XXX) -> use IsKeyPressed(ImGuiKey_XXX)\n - IsKeyPressed(GetKeyIndex(ImGuiKey_XXX)) -> use IsKeyPressed(ImGuiKey_XXX)\n - Backend writing to io.KeyMap[],io.KeysDown[] -> backend should call io.AddKeyEvent() (+ call io.SetKeyEventNativeData() if you want legacy user code to still function with legacy key codes).\n - Backend writing to io.KeyCtrl, io.KeyShift.. -> backend should call io.AddKeyEvent() with ImGuiMod_XXX values. *IF YOU PULLED CODE BETWEEN 2021/01/10 and 2021/01/27: We used to have a io.AddKeyModsEvent() function which was now replaced by io.AddKeyEvent() with ImGuiMod_XXX values.*\n - one case won't work with backward compatibility: if your custom backend used ImGuiKey as mock native indices (e.g. \"io.KeyMap[ImGuiKey_A] = ImGuiKey_A\") because those values are now larger than the legacy KeyDown[] array. Will assert.\n - inputs: added ImGuiKey_ModCtrl/ImGuiKey_ModShift/ImGuiKey_ModAlt/ImGuiKey_ModSuper values to submit keyboard modifiers using io.AddKeyEvent(), instead of writing directly to io.KeyCtrl, io.KeyShift, io.KeyAlt, io.KeySuper.\n - 2022/01/05 (1.87) - inputs: renamed ImGuiKey_KeyPadEnter to ImGuiKey_KeypadEnter to align with new symbols. Kept redirection enum.\n - 2022/01/05 (1.87) - removed io.ImeSetInputScreenPosFn() in favor of more flexible io.SetPlatformImeDataFn(). Removed 'void* io.ImeWindowHandle' in favor of writing to 'void* ImGuiViewport::PlatformHandleRaw'.\n - 2022/01/01 (1.87) - commented out redirecting functions/enums names that were marked obsolete in 1.69, 1.70, 1.71, 1.72 (March-July 2019)\n - ImGui::SetNextTreeNodeOpen() -> use ImGui::SetNextItemOpen()\n - ImGui::GetContentRegionAvailWidth() -> use ImGui::GetContentRegionAvail().x\n - ImGui::TreeAdvanceToLabelPos() -> use ImGui::SetCursorPosX(ImGui::GetCursorPosX() + ImGui::GetTreeNodeToLabelSpacing());\n - ImFontAtlas::CustomRect -> use ImFontAtlasCustomRect\n - ImGuiColorEditFlags_RGB/HSV/HEX -> use ImGuiColorEditFlags_DisplayRGB/HSV/Hex\n - 2021/12/20 (1.86) - backends: removed obsolete Marmalade backend (imgui_impl_marmalade.cpp) + example. Find last supported version at https://github.com/ocornut/imgui/wiki/Bindings\n - 2021/11/04 (1.86) - removed CalcListClipping() function. Prefer using ImGuiListClipper which can return non-contiguous ranges. Please open an issue if you think you really need this function.\n - 2021/08/23 (1.85) - removed GetWindowContentRegionWidth() function. keep inline redirection helper. can use 'GetWindowContentRegionMax().x - GetWindowContentRegionMin().x' instead for generally 'GetContentRegionAvail().x' is more useful.\n - 2021/07/26 (1.84) - commented out redirecting functions/enums names that were marked obsolete in 1.67 and 1.69 (March 2019):\n - ImGui::GetOverlayDrawList() -> use ImGui::GetForegroundDrawList()\n - ImFont::GlyphRangesBuilder -> use ImFontGlyphRangesBuilder\n - 2021/05/19 (1.83) - backends: obsoleted direct access to ImDrawCmd::TextureId in favor of calling ImDrawCmd::GetTexID().\n - if you are using official backends from the source tree: you have nothing to do.\n - if you have copied old backend code or using your own: change access to draw_cmd->TextureId to draw_cmd->GetTexID().\n - 2021/03/12 (1.82) - upgraded ImDrawList::AddRect(), AddRectFilled(), PathRect() to use ImDrawFlags instead of ImDrawCornersFlags.\n - ImDrawCornerFlags_TopLeft -> use ImDrawFlags_RoundCornersTopLeft\n - ImDrawCornerFlags_BotRight -> use ImDrawFlags_RoundCornersBottomRight\n - ImDrawCornerFlags_None -> use ImDrawFlags_RoundCornersNone etc.\n flags now sanely defaults to 0 instead of 0x0F, consistent with all other flags in the API.\n breaking: the default with rounding > 0.0f is now \"round all corners\" vs old implicit \"round no corners\":\n - rounding == 0.0f + flags == 0 --> meant no rounding --> unchanged (common use)\n - rounding > 0.0f + flags != 0 --> meant rounding --> unchanged (common use)\n - rounding == 0.0f + flags != 0 --> meant no rounding --> unchanged (unlikely use)\n - rounding > 0.0f + flags == 0 --> meant no rounding --> BREAKING (unlikely use): will now round all corners --> use ImDrawFlags_RoundCornersNone or rounding == 0.0f.\n this ONLY matters for hard coded use of 0 + rounding > 0.0f. Use of named ImDrawFlags_RoundCornersNone (new) or ImDrawCornerFlags_None (old) are ok.\n the old ImDrawCornersFlags used awkward default values of ~0 or 0xF (4 lower bits set) to signify \"round all corners\" and we sometimes encouraged using them as shortcuts.\n legacy path still support use of hard coded ~0 or any value from 0x1 or 0xF. They will behave the same with legacy paths enabled (will assert otherwise).\n - 2021/03/11 (1.82) - removed redirecting functions/enums names that were marked obsolete in 1.66 (September 2018):\n - ImGui::SetScrollHere() -> use ImGui::SetScrollHereY()\n - 2021/03/11 (1.82) - clarified that ImDrawList::PathArcTo(), ImDrawList::PathArcToFast() won't render with radius < 0.0f. Previously it sorts of accidentally worked but would generally lead to counter-clockwise paths and have an effect on anti-aliasing.\n - 2021/03/10 (1.82) - upgraded ImDrawList::AddPolyline() and PathStroke() \"bool closed\" parameter to \"ImDrawFlags flags\". The matching ImDrawFlags_Closed value is guaranteed to always stay == 1 in the future.\n - 2021/02/22 (1.82) - (*undone in 1.84*) win32+mingw: Re-enabled IME functions by default even under MinGW. In July 2016, issue #738 had me incorrectly disable those default functions for MinGW. MinGW users should: either link with -limm32, either set their imconfig file with '#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS'.\n - 2021/02/17 (1.82) - renamed rarely used style.CircleSegmentMaxError (old default = 1.60f) to style.CircleTessellationMaxError (new default = 0.30f) as the meaning of the value changed.\n - 2021/02/03 (1.81) - renamed ListBoxHeader(const char* label, ImVec2 size) to BeginListBox(). Kept inline redirection function (will obsolete).\n - removed ListBoxHeader(const char* label, int items_count, int height_in_items = -1) in favor of specifying size. Kept inline redirection function (will obsolete).\n - renamed ListBoxFooter() to EndListBox(). Kept inline redirection function (will obsolete).\n - 2021/01/26 (1.81) - removed ImGuiFreeType::BuildFontAtlas(). Kept inline redirection function. Prefer using '#define IMGUI_ENABLE_FREETYPE', but there's a runtime selection path available too. The shared extra flags parameters (very rarely used) are now stored in ImFontAtlas::FontBuilderFlags.\n - renamed ImFontConfig::RasterizerFlags (used by FreeType) to ImFontConfig::FontBuilderFlags.\n - renamed ImGuiFreeType::XXX flags to ImGuiFreeTypeBuilderFlags_XXX for consistency with other API.\n - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.63 (August 2018):\n - ImGui::IsItemDeactivatedAfterChange() -> use ImGui::IsItemDeactivatedAfterEdit().\n - ImGuiCol_ModalWindowDarkening -> use ImGuiCol_ModalWindowDimBg\n - ImGuiInputTextCallback -> use ImGuiTextEditCallback\n - ImGuiInputTextCallbackData -> use ImGuiTextEditCallbackData\n - 2020/12/21 (1.80) - renamed ImDrawList::AddBezierCurve() to AddBezierCubic(), and PathBezierCurveTo() to PathBezierCubicCurveTo(). Kept inline redirection function (will obsolete).\n - 2020/12/04 (1.80) - added imgui_tables.cpp file! Manually constructed project files will need the new file added!\n - 2020/11/18 (1.80) - renamed undocumented/internals ImGuiColumnsFlags_* to ImGuiOldColumnFlags_* in prevision of incoming Tables API.\n - 2020/11/03 (1.80) - renamed io.ConfigWindowsMemoryCompactTimer to io.ConfigMemoryCompactTimer as the feature will apply to other data structures\n - 2020/10/14 (1.80) - backends: moved all backends files (imgui_impl_XXXX.cpp, imgui_impl_XXXX.h) from examples/ to backends/.\n - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.60 (April 2018):\n - io.RenderDrawListsFn pointer -> use ImGui::GetDrawData() value and call the render function of your backend\n - ImGui::IsAnyWindowFocused() -> use ImGui::IsWindowFocused(ImGuiFocusedFlags_AnyWindow)\n - ImGui::IsAnyWindowHovered() -> use ImGui::IsWindowHovered(ImGuiHoveredFlags_AnyWindow)\n - ImGuiStyleVar_Count_ -> use ImGuiStyleVar_COUNT\n - ImGuiMouseCursor_Count_ -> use ImGuiMouseCursor_COUNT\n - removed redirecting functions names that were marked obsolete in 1.61 (May 2018):\n - InputFloat (... int decimal_precision ...) -> use InputFloat (... const char* format ...) with format = \"%.Xf\" where X is your value for decimal_precision.\n - same for InputFloat2()/InputFloat3()/InputFloat4() variants taking a `int decimal_precision` parameter.\n - 2020/10/05 (1.79) - removed ImGuiListClipper: Renamed constructor parameters which created an ambiguous alternative to using the ImGuiListClipper::Begin() function, with misleading edge cases (note: imgui_memory_editor <0.40 from imgui_club/ used this old clipper API. Update your copy if needed).\n - 2020/09/25 (1.79) - renamed ImGuiSliderFlags_ClampOnInput to ImGuiSliderFlags_AlwaysClamp. Kept redirection enum (will obsolete sooner because previous name was added recently).\n - 2020/09/25 (1.79) - renamed style.TabMinWidthForUnselectedCloseButton to style.TabMinWidthForCloseButton.\n - 2020/09/21 (1.79) - renamed OpenPopupContextItem() back to OpenPopupOnItemClick(), reverting the change from 1.77. For varieties of reason this is more self-explanatory.\n - 2020/09/21 (1.79) - removed return value from OpenPopupOnItemClick() - returned true on mouse release on an item - because it is inconsistent with other popup APIs and makes others misleading. It's also and unnecessary: you can use IsWindowAppearing() after BeginPopup() for a similar result.\n - 2020/09/17 (1.79) - removed ImFont::DisplayOffset in favor of ImFontConfig::GlyphOffset. DisplayOffset was applied after scaling and not very meaningful/useful outside of being needed by the default ProggyClean font. If you scaled this value after calling AddFontDefault(), this is now done automatically. It was also getting in the way of better font scaling, so let's get rid of it now!\n - 2020/08/17 (1.78) - obsoleted use of the trailing 'float power=1.0f' parameter for DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(), DragFloatRange2(), DragScalar(), DragScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(), SliderScalar(), SliderScalarN(), VSliderFloat() and VSliderScalar().\n replaced the 'float power=1.0f' argument with integer-based flags defaulting to 0 (as with all our flags).\n worked out a backward-compatibility scheme so hopefully most C++ codebase should not be affected. in short, when calling those functions:\n - if you omitted the 'power' parameter (likely!), you are not affected.\n - if you set the 'power' parameter to 1.0f (same as previous default value): 1/ your compiler may warn on float>int conversion, 2/ everything else will work. 3/ you can replace the 1.0f value with 0 to fix the warning, and be technically correct.\n - if you set the 'power' parameter to >1.0f (to enable non-linear editing): 1/ your compiler may warn on float>int conversion, 2/ code will assert at runtime, 3/ in case asserts are disabled, the code will not crash and enable the _Logarithmic flag. 4/ you can replace the >1.0f value with ImGuiSliderFlags_Logarithmic to fix the warning/assert and get a _similar_ effect as previous uses of power >1.0f.\n see https://github.com/ocornut/imgui/issues/3361 for all details.\n kept inline redirection functions (will obsolete) apart for: DragFloatRange2(), VSliderFloat(), VSliderScalar(). For those three the 'float power=1.0f' version was removed directly as they were most unlikely ever used.\n for shared code, you can version check at compile-time with `#if IMGUI_VERSION_NUM >= 17704`.\n - obsoleted use of v_min > v_max in DragInt, DragFloat, DragScalar to lock edits (introduced in 1.73, was not demoed nor documented very), will be replaced by a more generic ReadOnly feature. You may use the ImGuiSliderFlags_ReadOnly internal flag in the meantime.\n - 2020/06/23 (1.77) - removed BeginPopupContextWindow(const char*, int mouse_button, bool also_over_items) in favor of BeginPopupContextWindow(const char*, ImGuiPopupFlags flags) with ImGuiPopupFlags_NoOverItems.\n - 2020/06/15 (1.77) - renamed OpenPopupOnItemClick() to OpenPopupContextItem(). Kept inline redirection function (will obsolete). [NOTE: THIS WAS REVERTED IN 1.79]\n - 2020/06/15 (1.77) - removed CalcItemRectClosestPoint() entry point which was made obsolete and asserting in December 2017.\n - 2020/04/23 (1.77) - removed unnecessary ID (first arg) of ImFontAtlas::AddCustomRectRegular().\n - 2020/01/22 (1.75) - ImDrawList::AddCircle()/AddCircleFilled() functions don't accept negative radius any more.\n - 2019/12/17 (1.75) - [undid this change in 1.76] made Columns() limited to 64 columns by asserting above that limit. While the current code technically supports it, future code may not so we're putting the restriction ahead.\n - 2019/12/13 (1.75) - [imgui_internal.h] changed ImRect() default constructor initializes all fields to 0.0f instead of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by adding multiple points into it, you may need to fix your initial value.\n - 2019/12/08 (1.75) - removed redirecting functions/enums that were marked obsolete in 1.53 (December 2017):\n - ShowTestWindow() -> use ShowDemoWindow()\n - IsRootWindowFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootWindow)\n - IsRootWindowOrAnyChildFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows)\n - SetNextWindowContentWidth(w) -> use SetNextWindowContentSize(ImVec2(w, 0.0f))\n - GetItemsLineHeightWithSpacing() -> use GetFrameHeightWithSpacing()\n - ImGuiCol_ChildWindowBg -> use ImGuiCol_ChildBg\n - ImGuiStyleVar_ChildWindowRounding -> use ImGuiStyleVar_ChildRounding\n - ImGuiTreeNodeFlags_AllowOverlapMode -> use ImGuiTreeNodeFlags_AllowItemOverlap\n - IMGUI_DISABLE_TEST_WINDOWS -> use IMGUI_DISABLE_DEMO_WINDOWS\n - 2019/12/08 (1.75) - obsoleted calling ImDrawList::PrimReserve() with a negative count (which was vaguely documented and rarely if ever used). Instead, we added an explicit PrimUnreserve() API.\n - 2019/12/06 (1.75) - removed implicit default parameter to IsMouseDragging(int button = 0) to be consistent with other mouse functions (none of the other functions have it).\n - 2019/11/21 (1.74) - ImFontAtlas::AddCustomRectRegular() now requires an ID larger than 0x110000 (instead of 0x10000) to conform with supporting Unicode planes 1-16 in a future update. ID below 0x110000 will now assert.\n - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS to IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS for consistency.\n - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_MATH_FUNCTIONS to IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS for consistency.\n - 2019/10/22 (1.74) - removed redirecting functions/enums that were marked obsolete in 1.52 (October 2017):\n - Begin() [old 5 args version] -> use Begin() [3 args], use SetNextWindowSize() SetNextWindowBgAlpha() if needed\n - IsRootWindowOrAnyChildHovered() -> use IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows)\n - AlignFirstTextHeightToWidgets() -> use AlignTextToFramePadding()\n - SetNextWindowPosCenter() -> use SetNextWindowPos() with a pivot of (0.5f, 0.5f)\n - ImFont::Glyph -> use ImFontGlyph\n - 2019/10/14 (1.74) - inputs: Fixed a miscalculation in the keyboard/mouse \"typematic\" repeat delay/rate calculation, used by keys and e.g. repeating mouse buttons as well as the GetKeyPressedAmount() function.\n if you were using a non-default value for io.KeyRepeatRate (previous default was 0.250), you can add +io.KeyRepeatDelay to it to compensate for the fix.\n The function was triggering on: 0.0 and (delay+rate*N) where (N>=1). Fixed formula responds to (N>=0). Effectively it made io.KeyRepeatRate behave like it was set to (io.KeyRepeatRate + io.KeyRepeatDelay).\n If you never altered io.KeyRepeatRate nor used GetKeyPressedAmount() this won't affect you.\n - 2019/07/15 (1.72) - removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()). Kept redirection function (will obsolete).\n - 2019/07/12 (1.72) - renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Kept redirection typedef (will obsolete).\n - 2019/06/14 (1.72) - removed redirecting functions/enums names that were marked obsolete in 1.51 (June 2017): ImGuiCol_Column*, ImGuiSetCond_*, IsItemHoveredRect(), IsPosHoveringAnyWindow(), IsMouseHoveringAnyWindow(), IsMouseHoveringWindow(), IMGUI_ONCE_UPON_A_FRAME. Grep this log for details and new names, or see how they were implemented until 1.71.\n - 2019/06/07 (1.71) - rendering of child window outer decorations (bg color, border, scrollbars) is now performed as part of the parent window. If you have\n overlapping child windows in a same parent, and relied on their relative z-order to be mapped to their submission order, this will affect your rendering.\n This optimization is disabled if the parent window has no visual output, because it appears to be the most common situation leading to the creation of overlapping child windows.\n Please reach out if you are affected.\n - 2019/05/13 (1.71) - renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Kept inline redirection function (will obsolete).\n - 2019/05/11 (1.71) - changed io.AddInputCharacter(unsigned short c) signature to io.AddInputCharacter(unsigned int c).\n - 2019/04/29 (1.70) - improved ImDrawList thick strokes (>1.0f) preserving correct thickness up to 90 degrees angles (e.g. rectangles). If you have custom rendering using thick lines, they will appear thicker now.\n - 2019/04/29 (1.70) - removed GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead. Kept inline redirection function (will obsolete).\n - 2019/03/04 (1.69) - renamed GetOverlayDrawList() to GetForegroundDrawList(). Kept redirection function (will obsolete).\n - 2019/02/26 (1.69) - renamed ImGuiColorEditFlags_RGB/ImGuiColorEditFlags_HSV/ImGuiColorEditFlags_HEX to ImGuiColorEditFlags_DisplayRGB/ImGuiColorEditFlags_DisplayHSV/ImGuiColorEditFlags_DisplayHex. Kept redirection enums (will obsolete).\n - 2019/02/14 (1.68) - made it illegal/assert when io.DisplayTime == 0.0f (with an exception for the first frame). If for some reason your time step calculation gives you a zero value, replace it with an arbitrarily small value!\n - 2019/02/01 (1.68) - removed io.DisplayVisibleMin/DisplayVisibleMax (which were marked obsolete and removed from viewport/docking branch already).\n - 2019/01/06 (1.67) - renamed io.InputCharacters[], marked internal as was always intended. Please don't access directly, and use AddInputCharacter() instead!\n - 2019/01/06 (1.67) - renamed ImFontAtlas::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Kept redirection typedef (will obsolete).\n - 2018/12/20 (1.67) - made it illegal to call Begin(\"\") with an empty string. This somehow half-worked before but had various undesirable side-effects.\n - 2018/12/10 (1.67) - renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges as we are doing a large pass on configuration flags.\n - 2018/10/12 (1.66) - renamed misc/stl/imgui_stl.* to misc/cpp/imgui_stdlib.* in prevision for other C++ helper files.\n - 2018/09/28 (1.66) - renamed SetScrollHere() to SetScrollHereY(). Kept redirection function (will obsolete).\n - 2018/09/06 (1.65) - renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and stb_rect_pack.h to imstb_rectpack.h.\n If you were conveniently using the imgui copy of those STB headers in your project you will have to update your include paths.\n - 2018/09/05 (1.65) - renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427)\n - 2018/08/31 (1.64) - added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp. Re-ordered some of the code remaining in imgui.cpp.\n NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTION HAS BEEN MOVED.\n Because of this, any local modifications to imgui.cpp will likely conflict when you update. Read docs/CHANGELOG.txt for suggestions.\n - 2018/08/22 (1.63) - renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent).\n - 2018/08/21 (1.63) - renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. Kept redirection types (will obsolete).\n - 2018/08/21 (1.63) - removed ImGuiInputTextCallbackData::ReadOnly since it is a duplication of (ImGuiInputTextCallbackData::Flags & ImGuiInputTextFlags_ReadOnly).\n - 2018/08/01 (1.63) - removed per-window ImGuiWindowFlags_ResizeFromAnySide beta flag in favor of a global io.ConfigResizeWindowsFromEdges [update 1.67 renamed to ConfigWindowsResizeFromEdges] to enable the feature.\n - 2018/08/01 (1.63) - renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to ConfigMacOSXBehaviors for consistency.\n - 2018/07/22 (1.63) - changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time.\n - 2018/07/08 (1.63) - style: renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete).\n - 2018/06/08 (1.62) - examples: the imgui_impl_XXX files have been split to separate platform (Win32, GLFW, SDL2, etc.) from renderer (DX11, OpenGL, Vulkan, etc.).\n old backends will still work as is, however prefer using the separated backends as they will be updated to support multi-viewports.\n when adopting new backends follow the main.cpp code of your preferred examples/ folder to know which functions to call.\n in particular, note that old backends called ImGui::NewFrame() at the end of their ImGui_ImplXXXX_NewFrame() function.\n - 2018/06/06 (1.62) - renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish other variants and discourage using the full set.\n - 2018/06/06 (1.62) - TreeNodeEx()/TreeNodeBehavior(): the ImGuiTreeNodeFlags_CollapsingHeader helper now include the ImGuiTreeNodeFlags_NoTreePushOnOpen flag. See Changelog for details.\n - 2018/05/03 (1.61) - DragInt(): the default compile-time format string has been changed from \"%.0f\" to \"%d\", as we are not using integers internally any more.\n If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format.\n To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, giving time to users to upgrade their code.\n If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your codebase for e.g. \"DragInt.*%f\" to help you find them.\n - 2018/04/28 (1.61) - obsoleted InputFloat() functions taking an optional \"int decimal_precision\" in favor of an equivalent and more flexible \"const char* format\",\n consistent with other functions. Kept redirection functions (will obsolete).\n - 2018/04/09 (1.61) - IM_DELETE() helper function added in 1.60 doesn't clear the input _pointer_ reference, more consistent with expectation and allows passing r-value.\n - 2018/03/20 (1.60) - renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, _not_ used by core and only honored by some backend ahead of merging the Nav branch).\n - 2018/03/12 (1.60) - removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered as the closing cross uses regular button colors now.\n - 2018/03/08 (1.60) - changed ImFont::DisplayOffset.y to default to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. If you were adding or subtracting to ImFont::DisplayOffset check if your fonts are correctly aligned vertically.\n - 2018/03/03 (1.60) - renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums.\n - 2018/02/18 (1.60) - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment.\n - 2018/02/16 (1.60) - obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). Use ImGui::GetDrawData() to retrieve the ImDrawData* to display.\n - 2018/02/07 (1.60) - reorganized context handling to be more explicit,\n - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END.\n - removed Shutdown() function, as DestroyContext() serve this purpose.\n - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwise CreateContext() will create its own font atlas instance.\n - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts.\n - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts.\n - 2018/01/31 (1.60) - moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths.\n - 2018/01/11 (1.60) - obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete).\n - 2018/01/11 (1.60) - obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete).\n - 2018/01/03 (1.60) - renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData.\n - 2017/12/29 (1.60) - removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it it's easy to replicate on your side.\n - 2017/12/24 (1.53) - renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete).\n - 2017/12/21 (1.53) - ImDrawList: renamed style.AntiAliasedShapes to style.AntiAliasedFill for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags\n - 2017/12/21 (1.53) - ImDrawList: removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame.\n - 2017/12/14 (1.53) - using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set.\n - 2017/12/13 (1.53) - renamed GetItemsLineHeightWithSpacing() to GetFrameHeightWithSpacing(). Kept redirection function (will obsolete).\n - 2017/12/13 (1.53) - obsoleted IsRootWindowFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootWindow). Kept redirection function (will obsolete).\n - obsoleted IsRootWindowOrAnyChildFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows). Kept redirection function (will obsolete).\n - 2017/12/12 (1.53) - renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. Kept redirection enum (will obsolete).\n - 2017/12/10 (1.53) - removed SetNextWindowContentWidth(), prefer using SetNextWindowContentSize(). Kept redirection function (will obsolete).\n - 2017/11/27 (1.53) - renamed ImGuiTextBuffer::append() helper to appendf(), appendv() to appendfv(). If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed.\n - 2017/11/18 (1.53) - Style, Begin: removed ImGuiWindowFlags_ShowBorders window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. style.FrameBorderSize, style.WindowBorderSize). Use ImGui::ShowStyleEditor() to look them up.\n Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. It is recommended you use the StyleColorsClassic(), StyleColorsDark(), StyleColorsLight() functions.\n - 2017/11/18 (1.53) - Style: removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency.\n - 2017/11/18 (1.53) - Style: renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg.\n - 2017/11/18 (1.53) - Style: renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding.\n - 2017/11/02 (1.53) - obsoleted IsRootWindowOrAnyChildHovered() in favor of using IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows);\n - 2017/10/24 (1.52) - renamed IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS to IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS for consistency.\n - 2017/10/20 (1.52) - changed IsWindowHovered() default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it.\n - 2017/10/20 (1.52) - marked IsItemHoveredRect()/IsMouseHoveringWindow() as obsolete, in favor of using the newly introduced flags for IsItemHovered() and IsWindowHovered(). See https://github.com/ocornut/imgui/issues/1382 for details.\n removed the IsItemRectHovered()/IsWindowRectHovered() names introduced in 1.51 since they were merely more consistent names for the two functions we are now obsoleting.\n IsItemHoveredRect() --> IsItemHovered(ImGuiHoveredFlags_RectOnly)\n IsMouseHoveringAnyWindow() --> IsWindowHovered(ImGuiHoveredFlags_AnyWindow)\n IsMouseHoveringWindow() --> IsWindowHovered(ImGuiHoveredFlags_AllowWhenBlockedByPopup | ImGuiHoveredFlags_AllowWhenBlockedByActiveItem) [weird, old behavior]\n - 2017/10/17 (1.52) - marked the old 5-parameters version of Begin() as obsolete (still available). Use SetNextWindowSize()+Begin() instead!\n - 2017/10/11 (1.52) - renamed AlignFirstTextHeightToWidgets() to AlignTextToFramePadding(). Kept inline redirection function (will obsolete).\n - 2017/09/26 (1.52) - renamed ImFont::Glyph to ImFontGlyph. Kept redirection typedef (will obsolete).\n - 2017/09/25 (1.52) - removed SetNextWindowPosCenter() because SetNextWindowPos() now has the optional pivot information to do the same and more. Kept redirection function (will obsolete).\n - 2017/08/25 (1.52) - io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we now accept negative mouse coordinates. In your backend if you need to support unavailable mouse, make sure to replace \"io.MousePos = ImVec2(-1,-1)\" with \"io.MousePos = ImVec2(-FLT_MAX,-FLT_MAX)\".\n - 2017/08/22 (1.51) - renamed IsItemHoveredRect() to IsItemRectHovered(). Kept inline redirection function (will obsolete). -> (1.52) use IsItemHovered(ImGuiHoveredFlags_RectOnly)!\n - renamed IsMouseHoveringAnyWindow() to IsAnyWindowHovered() for consistency. Kept inline redirection function (will obsolete).\n - renamed IsMouseHoveringWindow() to IsWindowRectHovered() for consistency. Kept inline redirection function (will obsolete).\n - 2017/08/20 (1.51) - renamed GetStyleColName() to GetStyleColorName() for consistency.\n - 2017/08/20 (1.51) - added PushStyleColor(ImGuiCol idx, ImU32 col) overload, which _might_ cause an \"ambiguous call\" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicitly to fix.\n - 2017/08/15 (1.51) - marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame type.\n - 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow() from (const char*,int buttons,bool also_over_items) to (const char*,int buttons,bool also_over_items). Note that most calls relied on default parameters completely.\n - 2017/08/13 (1.51) - renamed ImGuiCol_Column to ImGuiCol_Separator, ImGuiCol_ColumnHovered to ImGuiCol_SeparatorHovered, ImGuiCol_ColumnActive to ImGuiCol_SeparatorActive. Kept redirection enums (will obsolete).\n - 2017/08/11 (1.51) - renamed ImGuiSetCond_Always to ImGuiCond_Always, ImGuiSetCond_Once to ImGuiCond_Once, ImGuiSetCond_FirstUseEver to ImGuiCond_FirstUseEver, ImGuiSetCond_Appearing to ImGuiCond_Appearing. Kept redirection enums (will obsolete).\n - 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton().\n - 2017/08/08 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu.\n - changed prototype of 'ColorEdit4(const char* label, float col[4], bool show_alpha = true)' to 'ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)', where passing flags = 0x01 is a safe no-op (hello dodgy backward compatibility!). - check and run the demo window, under \"Color/Picker Widgets\", to understand the various new options.\n - changed prototype of rarely used 'ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)' to 'ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0, 0))'\n - 2017/07/20 (1.51) - removed IsPosHoveringAnyWindow(ImVec2), which was partly broken and misleading. ASSERT + redirect user to io.WantCaptureMouse\n - 2017/05/26 (1.50) - removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset.\n - 2017/05/01 (1.50) - renamed ImDrawList::PathFill() (rarely used directly) to ImDrawList::PathFillConvex() for clarity.\n - 2016/11/06 (1.50) - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetID() and use it instead of passing string to BeginChild().\n - 2016/10/15 (1.50) - avoid 'void* user_data' parameter to io.SetClipboardTextFn/io.GetClipboardTextFn pointers. We pass io.ClipboardUserData to it.\n - 2016/09/25 (1.50) - style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc.\n - 2016/07/30 (1.50) - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully, breakage should be minimal.\n - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore.\n If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you, otherwise if <1.0f you need to tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar.\n This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color:\n ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col) { float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a; return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a); }\n If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color.\n - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext().\n - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection.\n - 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the \"default_open = true\" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen).\n - 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDrawList::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer.\n - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref GitHub issue #337).\n - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337)\n - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete).\n - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert.\n - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you.\n - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis.\n - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete.\n - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position.\n GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side.\n GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out!\n - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize\n - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project.\n - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason\n - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure.\n you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text.\n - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost.\n this necessary change will break your rendering function! the fix should be very easy. sorry for that :(\n - if you are using a vanilla copy of one of the imgui_impl_XXX.cpp provided in the example, you just need to update your copy and you can ignore the rest.\n - the signature of the io.RenderDrawListsFn handler has changed!\n old: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count)\n new: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data).\n parameters: 'cmd_lists' becomes 'draw_data->CmdLists', 'cmd_lists_count' becomes 'draw_data->CmdListsCount'\n ImDrawList: 'commands' becomes 'CmdBuffer', 'vtx_buffer' becomes 'VtxBuffer', 'IdxBuffer' is new.\n ImDrawCmd: 'vtx_count' becomes 'ElemCount', 'clip_rect' becomes 'ClipRect', 'user_callback' becomes 'UserCallback', 'texture_id' becomes 'TextureId'.\n - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer.\n - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering!\n - refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade!\n - 2015/07/10 (1.43) - changed SameLine() parameters from int to float.\n - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete).\n - 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount.\n - 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence\n - 2015/06/14 (1.41) - changed Selectable() API from (label, selected, size) to (label, selected, flags, size). Size override should have been rarely used. Sorry!\n - 2015/05/31 (1.40) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete).\n - 2015/05/31 (1.40) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete).\n - 2015/05/27 (1.40) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons.\n - 2015/05/11 (1.40) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the \"open\" state of a popup. BeginPopup() returns true if the popup is opened.\n - 2015/05/03 (1.40) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same).\n - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function until 1.50.\n - 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API\n - 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive.\n - 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead.\n - 2015/03/17 (1.36) - renamed GetItemBoxMin()/GetItemBoxMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect(). Kept inline redirection function until 1.50.\n - 2015/03/15 (1.36) - renamed style.TreeNodeSpacing to style.IndentSpacing, ImGuiStyleVar_TreeNodeSpacing to ImGuiStyleVar_IndentSpacing\n - 2015/03/13 (1.36) - renamed GetWindowIsFocused() to IsWindowFocused(). Kept inline redirection function until 1.50.\n - 2015/03/08 (1.35) - renamed style.ScrollBarWidth to style.ScrollbarWidth (casing)\n - 2015/02/27 (1.34) - renamed OpenNextNode(bool) to SetNextTreeNodeOpened(bool, ImGuiSetCond). Kept inline redirection function until 1.50.\n - 2015/02/27 (1.34) - renamed ImGuiSetCondition_*** to ImGuiSetCond_***, and _FirstUseThisSession becomes _Once.\n - 2015/02/11 (1.32) - changed text input callback ImGuiTextEditCallback return type from void-->int. reserved for future use, return 0 for now.\n - 2015/02/10 (1.32) - renamed GetItemWidth() to CalcItemWidth() to clarify its evolving behavior\n - 2015/02/08 (1.31) - renamed GetTextLineSpacing() to GetTextLineHeightWithSpacing()\n - 2015/02/01 (1.31) - removed IO.MemReallocFn (unused)\n - 2015/01/19 (1.30) - renamed ImGuiStorage::GetIntPtr()/GetFloatPtr() to GetIntRef()/GetIntRef() because Ptr was conflicting with actual pointer storage functions.\n - 2015/01/11 (1.30) - big font/image API change! now loads TTF file. allow for multiple fonts. no need for a PNG loader.\n - 2015/01/11 (1.30) - removed GetDefaultFontData(). uses io.Fonts->GetTextureData*() API to retrieve uncompressed pixels.\n - old: const void* png_data; unsigned int png_size; ImGui::GetDefaultFontData(NULL, NULL, &png_data, &png_size); [..Upload texture to GPU..];\n - new: unsigned char* pixels; int width, height; io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); [..Upload texture to GPU..]; io.Fonts->SetTexID(YourTexIdentifier);\n you now have more flexibility to load multiple TTF fonts and manage the texture buffer for internal needs. It is now recommended that you sample the font texture with bilinear interpolation.\n - 2015/01/11 (1.30) - added texture identifier in ImDrawCmd passed to your render function (we can now render images). make sure to call io.Fonts->SetTexID()\n - 2015/01/11 (1.30) - removed IO.PixelCenterOffset (unnecessary, can be handled in user projection matrix)\n - 2015/01/11 (1.30) - removed ImGui::IsItemFocused() in favor of ImGui::IsItemActive() which handles all widgets\n - 2014/12/10 (1.18) - removed SetNewWindowDefaultPos() in favor of new generic API SetNextWindowPos(pos, ImGuiSetCondition_FirstUseEver)\n - 2014/11/28 (1.17) - moved IO.Font*** options to inside the IO.Font-> structure (FontYOffset, FontTexUvForWhite, FontBaseScale, FontFallbackGlyph)\n - 2014/11/26 (1.17) - reworked syntax of IMGUI_ONCE_UPON_A_FRAME helper macro to increase compiler compatibility\n - 2014/11/07 (1.15) - renamed IsHovered() to IsItemHovered()\n - 2014/10/02 (1.14) - renamed IMGUI_INCLUDE_IMGUI_USER_CPP to IMGUI_INCLUDE_IMGUI_USER_INL and imgui_user.cpp to imgui_user.inl (more IDE friendly)\n - 2014/09/25 (1.13) - removed 'text_end' parameter from IO.SetClipboardTextFn (the string is now always zero-terminated for simplicity)\n - 2014/09/24 (1.12) - renamed SetFontScale() to SetWindowFontScale()\n - 2014/09/24 (1.12) - moved IM_MALLOC/IM_REALLOC/IM_FREE preprocessor defines to IO.MemAllocFn/IO.MemReallocFn/IO.MemFreeFn\n - 2014/08/30 (1.09) - removed IO.FontHeight (now computed automatically)\n - 2014/08/30 (1.09) - moved IMGUI_FONT_TEX_UV_FOR_WHITE preprocessor define to IO.FontTexUvForWhite\n - 2014/08/28 (1.09) - changed the behavior of IO.PixelCenterOffset following various rendering fixes\n\n\n FREQUENTLY ASKED QUESTIONS (FAQ)\n ================================\n\n Read all answers online:\n https://www.dearimgui.com/faq or https://github.com/ocornut/imgui/blob/master/docs/FAQ.md (same url)\n Read all answers locally (with a text editor or ideally a Markdown viewer):\n docs/FAQ.md\n Some answers are copied down here to facilitate searching in code.\n\n Q&A: Basics\n ===========\n\n Q: Where is the documentation?\n A: This library is poorly documented at the moment and expects the user to be acquainted with C/C++.\n - Run the examples/ applications and explore them.\n - Read Getting Started (https://github.com/ocornut/imgui/wiki/Getting-Started) guide.\n - See demo code in imgui_demo.cpp and particularly the ImGui::ShowDemoWindow() function.\n - The demo covers most features of Dear ImGui, so you can read the code and see its output.\n - See documentation and comments at the top of imgui.cpp + effectively imgui.h.\n - 20+ standalone example applications using e.g. OpenGL/DirectX are provided in the\n examples/ folder to explain how to integrate Dear ImGui with your own engine/application.\n - The Wiki (https://github.com/ocornut/imgui/wiki) has many resources and links.\n - The Glossary (https://github.com/ocornut/imgui/wiki/Glossary) page also may be useful.\n - Your programming IDE is your friend, find the type or function declaration to find comments\n associated with it.\n\n Q: What is this library called?\n Q: What is the difference between Dear ImGui and traditional UI toolkits?\n Q: Which version should I get?\n >> This library is called \"Dear ImGui\", please don't call it \"ImGui\" :)\n >> See https://www.dearimgui.com/faq for details.\n\n Q&A: Integration\n ================\n\n Q: How to get started?\n A: Read https://github.com/ocornut/imgui/wiki/Getting-Started.

This allowed backends requiring 64-bit worth of data to build on 32-bit architectures.

We will work toward simplifying and demoing it.\n// - In the spirit of Dear ImGui design, your code owns actual selection data.\n// This is designed to allow all kinds of selection storage you may use in your application e.g. set/map/hash.\n// About ImGuiSelectionBasicStorage:\n// - This is an optional helper to store a selection state and apply selection requests.\n// - It is used by our demos and provided as a convenience to quickly implement multi-selection.\n// Usage:\n// - Identify submitted items with SetNextItemSelectionUserData(), most likely using an index into your current data-set.\n// - Store and maintain actual selection data using persistent object identifiers.\n// - Usage flow:\n// BEGIN - (1) Call BeginMultiSelect() and retrieve the ImGuiMultiSelectIO* result.\n// - (2) Honor request list (SetAll/SetRange requests) by updating your selection data. Same code as Step 6.\n// - (3) [If using clipper] You need to make sure RangeSrcItem is always submitted. Calculate its index and pass to clipper.IncludeItemByIndex(). If storing indices in ImGuiSelectionUserData, a simple clipper.IncludeItemByIndex(ms_io->RangeSrcItem) call will work.\n// LOOP - (4) Submit your items with SetNextItemSelectionUserData() + Selectable()/TreeNode() calls.\n// END - (5) Call EndMultiSelect() and retrieve the ImGuiMultiSelectIO* result.\n// - (6) Honor request list (SetAll/SetRange requests) by updating your selection data. Same code as Step 2.\n// If you submit all items (no clipper), Step 2 and 3 are optional and will be handled by each item themselves. It is fine to always honor those steps.\n// About ImGuiSelectionUserData:\n// - This can store an application-defined identifier (e.g. index or pointer) submitted via SetNextItemSelectionUserData().\n// - In return we store them into RangeSrcItem/RangeFirstItem/RangeLastItem and other fields in ImGuiMultiSelectIO.\n// - Most applications will store an object INDEX, hence the chosen name and type. Storing an index is natural, because\n// SetRange requests will give you two end-points and you will need to iterate/interpolate between them to update your selection.\n// - However it is perfectly possible to store a POINTER or another IDENTIFIER inside ImGuiSelectionUserData.\n// Our system never assume that you identify items by indices, it never attempts to interpolate between two values.\n// - If you enable ImGuiMultiSelectFlags_NoRangeSelect then it is guaranteed that you will never have to interpolate\n// between two ImGuiSelectionUserData, which may be a convenient way to use part of the feature with less code work.\n// - As most users will want to store an index, for convenience and to reduce confusion we use ImS64 instead of void*,\n// being syntactically easier to downcast.

Either way, carefully follow and refer to examples/ backends for details.\n// - Application: Enable feature with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.\n// - Backend: Hook ImGuiPlatformIO's Platform_* and Renderer_* callbacks (see below).\n// Set 'io.BackendFlags |= ImGuiBackendFlags_PlatformHasViewports' and 'io.BackendFlags |= ImGuiBackendFlags_PlatformHasViewports'.\n// Update ImGuiPlatformIO's Monitors list every frame.\n// Update MousePos every frame, in absolute coordinates.\n// - Application: In your main loop, call ImGui::UpdatePlatformWindows(), ImGui::RenderPlatformWindowsDefault() after EndFrame() or Render().\n// You may skip calling RenderPlatformWindowsDefault() if its API is not convenient for your needs. Read comments below.\n// - Application: Fix absolute coordinates used in ImGui::SetWindowPos() or ImGui::SetNextWindowPos() calls.\n//\n// About ImGui::RenderPlatformWindowsDefault():\n// - This function is a mostly a _helper_ for the common-most cases, and to facilitate using default backends.\n// - You can check its simple source code to understand what it does.\n// It basically iterates secondary viewports and call 4 functions that are setup in ImGuiPlatformIO, if available:\n// Platform_RenderWindow(), Renderer_RenderWindow(), Platform_SwapBuffers(), Renderer_SwapBuffers()\n// Those functions pointers exists only for the benefit of RenderPlatformWindowsDefault().\n// - If you have very specific rendering needs (e.g. flipping multiple swap-chain simultaneously, unusual sync/threading issues, etc.),\n// you may be tempted to ignore RenderPlatformWindowsDefault() and write customized code to perform your renderingg.\n// You may decide to setup the platform_io's *RenderWindow and *SwapBuffers pointers and call your functions through those pointers,\n// or you may decide to never setup those pointers and call your code directly.

It is the most useful reference code that you and other coders will want to refer to and call.\n// Have the ImGui::ShowDemoWindow() function wired in an always-available debug menu of your game/app!\n// Also include Metrics! ItemPicker! DebugLog! and other debug features.\n// Removing this file from your project is hindering access to documentation for everyone in your team,\n// likely leading you to poorer usage of the library.\n// Everything in this file will be stripped out by the linker if you don't call ImGui::ShowDemoWindow().\n// If you want to link core Dear ImGui in your shipped builds but want a thorough guarantee that the demo will not be\n// linked, you can setup your imconfig.h with #define IMGUI_DISABLE_DEMO_WINDOWS and those functions will be empty.\n// In another situation, whenever you have Dear ImGui available you probably want this to be available for reference.\n// Thank you,\n// -Your beloved friend, imgui_demo.cpp (which you won't delete)\n\n//--------------------------------------------\n// ABOUT THE MEANING OF THE 'static' KEYWORD:\n//--------------------------------------------\n// In this demo code, we frequently use 'static' variables inside functions.\n// A static variable persists across calls. It is essentially a global variable but declared inside the scope of the function.\n// Think of \"static int n = 0;\" as \"global int n = 0;\" !\n// We do this IN THE DEMO because we want:\n// - to gather code and data in the same place.\n// - to make the demo source code faster to read, faster to change, smaller in size.\n// - it is also a convenient way of storing simple UI related information as long as your function\n// doesn't need to be reentrant or used in multiple threads.\n// This might be a pattern you will want to use in your code, but most of the data you would be working\n// with in a complex codebase is likely going to be stored outside your functions.\n\n//-----------------------------------------\n// ABOUT THE CODING STYLE OF OUR DEMO CODE\n//-----------------------------------------\n// The Demo code in this file is designed to be easy to copy-and-paste into your application!\n// Because of this:\n// - We never omit the ImGui:: prefix when calling functions, even though most code here is in the same namespace.\n// - We try to declare static variables in the local scope, as close as possible to the code using them.\n// - We never use any of the helpers/facilities used internally by Dear ImGui, unless available in the public API.\n// - We never use maths operators on ImVec2/ImVec4. For our other sources files we use them, and they are provided\n// by imgui.h using the IMGUI_DEFINE_MATH_OPERATORS define. For your own sources file they are optional\n// and require you either enable those, either provide your own via IM_VEC2_CLASS_EXTRA in imconfig.h.\n// Because we can't assume anything about your support of maths operators, we cannot use them in imgui_demo.cpp.\n\n// Navigating this file:\n// - In Visual Studio: Ctrl+Comma (\"Edit.GoToAll\") can follow symbols inside comments, whereas Ctrl+F12 (\"Edit.GoToImplementation\") cannot.\n// - In Visual Studio w/ Visual Assist installed: Alt+G (\"VAssistX.GoToImplementation\") can also follow symbols inside comments.\n// - In VS Code, CLion, etc.: Ctrl+Click can follow symbols inside comments.\n// - You can search/grep for all sections listed in the index to find the section.\n\n/*\n\nIndex of this file:\n\n// [SECTION] Forward Declarations\n// [SECTION] Helpers\n// [SECTION] Demo Window / ShowDemoWindow()\n// [SECTION] DemoWindowMenuBar()\n// [SECTION] Helpers: ExampleTreeNode, ExampleMemberInfo (for use by Property Editor & Multi-Select demos)\n// [SECTION] DemoWindowWidgetsBasic()\n// [SECTION] DemoWindowWidgetsBullets()\n// [SECTION] DemoWindowWidgetsCollapsingHeaders()\n// [SECTION] DemoWindowWidgetsComboBoxes()\n// [SECTION] DemoWindowWidgetsColorAndPickers()\n// [SECTION] DemoWindowWidgetsDataTypes()\n// [SECTION] DemoWindowWidgetsDisableBlocks()\n// [SECTION] DemoWindowWidgetsDragAndDrop()\n// [SECTION] DemoWindowWidgetsDragsAndSliders()\n// [SECTION] DemoWindowWidgetsFonts()\n// [SECTION] DemoWindowWidgetsImages()\n// [SECTION] DemoWindowWidgetsListBoxes()\n// [SECTION] DemoWindowWidgetsMultiComponents()\n// [SECTION] DemoWindowWidgetsPlotting()\n// [SECTION] DemoWindowWidgetsProgressBars()\n// [SECTION] DemoWindowWidgetsQueryingStatuses()\n// [SECTION] DemoWindowWidgetsSelectables()\n// [SECTION] DemoWindowWidgetsSelectionAndMultiSelect()\n// [SECTION] DemoWindowWidgetsTabs()\n// [SECTION] DemoWindowWidgetsText()\n// [SECTION] DemoWindowWidgetsTextFilter()\n// [SECTION] DemoWindowWidgetsTextInput()\n// [SECTION] DemoWindowWidgetsTooltips()\n// [SECTION] DemoWindowWidgetsTreeNodes()\n// [SECTION] DemoWindowWidgetsVerticalSliders()\n// [SECTION] DemoWindowWidgets()\n// [SECTION] DemoWindowLayout()\n// [SECTION] DemoWindowPopups()\n// [SECTION] DemoWindowTables()\n// [SECTION] DemoWindowInputs()\n// [SECTION] About Window / ShowAboutWindow()\n// [SECTION] Style Editor / ShowStyleEditor()\n// [SECTION] User Guide / ShowUserGuide()\n// [SECTION] Example App: Main Menu Bar / ShowExampleAppMainMenuBar()\n// [SECTION] Example App: Debug Console / ShowExampleAppConsole()\n// [SECTION] Example App: Debug Log / ShowExampleAppLog()\n// [SECTION] Example App: Simple Layout / ShowExampleAppLayout()\n// [SECTION] Example App: Property Editor / ShowExampleAppPropertyEditor()\n// [SECTION] Example App: Long Text / ShowExampleAppLongText()\n// [SECTION] Example App: Auto Resize / ShowExampleAppAutoResize()\n// [SECTION] Example App: Constrained Resize / ShowExampleAppConstrainedResize()\n// [SECTION] Example App: Simple overlay / ShowExampleAppSimpleOverlay()\n// [SECTION] Example App: Fullscreen window / ShowExampleAppFullscreen()\n// [SECTION] Example App: Manipulating window titles / ShowExampleAppWindowTitles()\n// [SECTION] Example App: Custom Rendering using ImDrawList API / ShowExampleAppCustomRendering()\n// [SECTION] Example App: Docking, DockSpace / ShowExampleAppDockSpace()\n// [SECTION] Example App: Documents Handling / ShowExampleAppDocuments()\n// [SECTION] Example App: Assets Browser / ShowExampleAppAssetsBrowser()\n\n*/\n\n#if defined(_MSC_VER) && !defined(_CRT_SECURE_NO_WARNINGS)\n#define _CRT_SECURE_NO_WARNINGS\n#endif\n\n#include \"imgui.h\"\n#ifndef IMGUI_DISABLE\n\n// System includes\n#include // toupper\n#include // INT_MIN, INT_MAX\n#include // sqrtf, powf, cosf, sinf, floorf, ceilf\n#include // vsnprintf, sscanf, printf\n#include // NULL, malloc, free, atoi\n#include // intptr_t\n#if !defined(_MSC_VER) || _MSC_VER >= 1800\n#include // PRId64/PRIu64, not avail in some MinGW headers.\n#endif\n#ifdef __EMSCRIPTEN__\n#include // __EMSCRIPTEN_MAJOR__ etc.\n#endif\n\n// Visual Studio warnings\n#ifdef _MSC_VER\n#pragma warning (disable: 4127) // condition expression is constant\n#pragma warning (disable: 4996) // 'This function or variable may be unsafe': strcpy, strdup, sprintf, vsnprintf, sscanf, fopen\n#pragma warning (disable: 26451) // [Static Analyzer] Arithmetic overflow : Using operator 'xxx' on a 4 byte value and then casting the result to an 8 byte value.

Not meaningful if parent window can vertically scroll.\n// - outer_size.y = 0.0f -> No minimum height (but will auto extend, unless _NoHostExtendY is set)\n// - outer_size.y > 0.0f -> Set Minimum height (but will auto extend, unless _NoHostExtendY is set)\n// Y with ScrollX/ScrollY enabled: using a child window for scrolling\n// - outer_size.y < 0.0f -> Bottom-align.

Recommended when using Scrolling on any axis.\n//-----------------------------------------------------------------------------\n// Outer size is also affected by the NoHostExtendX/NoHostExtendY flags.\n// Important to note how the two flags have slightly different behaviors!\n// - ImGuiTableFlags_NoHostExtendX -> Make outer width auto-fit to columns (overriding outer_size.x value). Only available when ScrollX/ScrollY are disabled and Stretch columns are not used.\n// - ImGuiTableFlags_NoHostExtendY -> Make outer height stop exactly at outer_size.y (prevent auto-extending table past the limit). Only available when ScrollX/ScrollY is disabled. Data below the limit will be clipped and not visible.\n// In theory ImGuiTableFlags_NoHostExtendY could be the default and any non-scrolling tables with outer_size.y != 0.0f would use exact height.\n// This would be consistent but perhaps less useful and more confusing (as vertically clipped items are not useful and not easily noticeable).\n//-----------------------------------------------------------------------------\n// About 'inner_width':\n// With ScrollX disabled:\n// - inner_width -> *ignored*\n// With ScrollX enabled:\n// - inner_width < 0.0f -> *illegal* fit in known width (right align from outer_size.x) <-- weird\n// - inner_width = 0.0f -> fit in outer_width: Fixed size columns will take space they need (if avail, otherwise shrink down), Stretch columns becomes Fixed columns.\n// - inner_width > 0.0f -> override scrolling width, generally to be larger than outer_size.x. Fixed column take space they need (if avail, otherwise shrink down), Stretch columns share remaining space!\n//-----------------------------------------------------------------------------\n// Details:\n// - If you want to use Stretch columns with ScrollX, you generally need to specify 'inner_width' otherwise the concept\n// of \"available space\" doesn't make sense.\n// - Even if not really useful, we allow 'inner_width < outer_size.x' for consistency and to facilitate understanding\n// of what the value does.\n//-----------------------------------------------------------------------------\n\n//-----------------------------------------------------------------------------\n// COLUMNS SIZING POLICIES\n// (Reference: ImGuiTableFlags_SizingXXX flags and ImGuiTableColumnFlags_WidthXXX flags)\n//-----------------------------------------------------------------------------\n// About overriding column sizing policy and width/weight with TableSetupColumn():\n// We use a default parameter of -1 for 'init_width'/'init_weight'.\n// - with ImGuiTableColumnFlags_WidthFixed, init_width <= 0 (default) --> width is automatic\n// - with ImGuiTableColumnFlags_WidthFixed, init_width > 0 (explicit) --> width is custom\n// - with ImGuiTableColumnFlags_WidthStretch, init_weight <= 0 (default) --> weight is 1.0f\n// - with ImGuiTableColumnFlags_WidthStretch, init_weight > 0 (explicit) --> weight is custom\n// Widths are specified _without_ CellPadding. If you specify a width of 100.0f, the column will be cover (100.0f + Padding * 2.0f)\n// and you can fit a 100.0f wide item in it without clipping and with padding honored.\n//-----------------------------------------------------------------------------\n// About default sizing policy (if you don't specify a ImGuiTableColumnFlags_WidthXXXX flag)\n// - with Table policy ImGuiTableFlags_SizingFixedFit --> default Column policy is ImGuiTableColumnFlags_WidthFixed, default Width is equal to contents width\n// - with Table policy ImGuiTableFlags_SizingFixedSame --> default Column policy is ImGuiTableColumnFlags_WidthFixed, default Width is max of all contents width\n// - with Table policy ImGuiTableFlags_SizingStretchSame --> default Column policy is ImGuiTableColumnFlags_WidthStretch, default Weight is 1.0f\n// - with Table policy ImGuiTableFlags_SizingStretchWeight --> default Column policy is ImGuiTableColumnFlags_WidthStretch, default Weight is proportional to contents\n// Default Width and default Weight can be overridden when calling TableSetupColumn().\n//-----------------------------------------------------------------------------\n// About mixing Fixed/Auto and Stretch columns together:\n// - the typical use of mixing sizing policies is: any number of LEADING Fixed columns, followed by one or two TRAILING Stretch columns.\n// - using mixed policies with ScrollX does not make much sense, as using Stretch columns with ScrollX does not make much sense in the first place!\n// that is, unless 'inner_width' is passed to BeginTable() to explicitly provide a total width to layout columns in.\n// - when using ImGuiTableFlags_SizingFixedSame with mixed columns, only the Fixed/Auto columns will match their widths to the width of the maximum contents.\n// - when using ImGuiTableFlags_SizingStretchSame with mixed columns, only the Stretch columns will match their weights/widths.\n//-----------------------------------------------------------------------------\n// About using column width:\n// If a column is manually resizable or has a width specified with TableSetupColumn():\n// - you may use GetContentRegionAvail().x to query the width available in a given column.\n// - right-side alignment features such as SetNextItemWidth(-x) or PushItemWidth(-x) will rely on this width.\n// If the column is not resizable and has no width specified with TableSetupColumn():\n// - its width will be automatic and be set to the max of items submitted.\n// - therefore you generally cannot have ALL items of the columns use e.g. SetNextItemWidth(-FLT_MIN).\n// - but if the column has one or more items of known/fixed size, this will become the reference width used by SetNextItemWidth(-FLT_MIN).\n//-----------------------------------------------------------------------------\n\n\n//-----------------------------------------------------------------------------\n// TABLES CLIPPING/CULLING\n//-----------------------------------------------------------------------------\n// About clipping/culling of Rows in Tables:\n// - For large numbers of rows, it is recommended you use ImGuiListClipper to submit only visible rows.\n// ImGuiListClipper is reliant on the fact that rows are of equal height.\n// See 'Demo->Tables->Vertical Scrolling' or 'Demo->Tables->Advanced' for a demo of using the clipper.\n// - Note that auto-resizing columns don't play well with using the clipper.\n// By default a table with _ScrollX but without _Resizable will have column auto-resize.\n// So, if you want to use the clipper, make sure to either enable _Resizable, either setup columns width explicitly with _WidthFixed.\n//-----------------------------------------------------------------------------\n// About clipping/culling of Columns in Tables:\n// - Both TableSetColumnIndex() and TableNextColumn() return true when the column is visible or performing\n// width measurements. Otherwise, you may skip submitting the contents of a cell/column, BUT ONLY if you know\n// it is not going to contribute to row height.\n// In many situations, you may skip submitting contents for every column but one (e.g. the first one).\n// - Case A: column is not hidden by user, and at least partially in sight (most common case).\n// - Case B: column is clipped / out of sight (because of scrolling or parent ClipRect): TableNextColumn() return false as a hint but we still allow layout output.\n// - Case C: column is hidden explicitly by the user (e.g. via the context menu, or _DefaultHide column flag, etc.).\n//\n// [A] [B] [C]\n// TableNextColumn(): true false false -> [userland] when TableNextColumn() / TableSetColumnIndex() returns false, user can skip submitting items but only if the column doesn't contribute to row height.\n// SkipItems: false false true -> [internal] when SkipItems is true, most widgets will early out if submitted, resulting is no layout output.\n// ClipRect: normal zero-width zero-width -> [internal] when ClipRect is zero, ItemAdd() will return false and most widgets will early out mid-way.\n// ImDrawList output: normal dummy dummy -> [internal] when using the dummy channel, ImDrawList submissions (if any) will be wasted (because cliprect is zero-width anyway).\n//\n// - We need to distinguish those cases because non-hidden columns that are clipped outside of scrolling bounds should still contribute their height to the row.\n// However, in the majority of cases, the contribution to row height is the same for all columns, or the tallest cells are known by the programmer.\n//-----------------------------------------------------------------------------\n// About clipping/culling of whole Tables:\n// - Scrolling tables with a known outer size can be clipped earlier as BeginTable() will return false.\n//-----------------------------------------------------------------------------\n\n//-----------------------------------------------------------------------------\n// [SECTION] Header mess\n//-----------------------------------------------------------------------------\n\n#if defined(_MSC_VER) && !defined(_CRT_SECURE_NO_WARNINGS)\n#define _CRT_SECURE_NO_WARNINGS\n#endif\n\n#ifndef IMGUI_DEFINE_MATH_OPERATORS\n#define IMGUI_DEFINE_MATH_OPERATORS\n#endif\n\n#include \"imgui.h\"\n#ifndef IMGUI_DISABLE\n#include \"imgui_internal.h\"\n\n// System includes\n#include // intptr_t\n\n// Visual Studio warnings\n#ifdef _MSC_VER\n#pragma warning (disable: 4127) // condition expression is constant\n#pragma warning (disable: 4996) // 'This function or variable may be unsafe': strcpy, strdup, sprintf, vsnprintf, sscanf, fopen\n#if defined(_MSC_VER) && _MSC_VER >= 1922 // MSVC 2019 16.2 or later\n#pragma warning (disable: 5054) // operator '|': deprecated between enumerations of different types\n#endif\n#pragma warning (disable: 26451) // [Static Analyzer] Arithmetic overflow : Using operator 'xxx' on a 4 byte value and then casting the result to a 8 byte value.

In this mode, it declares a\n// single public symbol, STB_TexteditState, which encapsulates the current\n// state of a text widget (except for the string, which you will store\n// separately).\n//\n// To compile in this mode, you must define STB_TEXTEDIT_CHARTYPE to a\n// primitive type that defines a single character (e.g. char, wchar_t, etc).\n//\n// To save space or increase undo-ability, you can optionally define the\n// following things that are used by the undo system:\n//\n// STB_TEXTEDIT_POSITIONTYPE small int type encoding a valid cursor position\n// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow\n// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer\n//\n// If you don't define these, they are set to permissive types and\n// moderate sizes. The undo system does no memory allocations, so\n// it grows STB_TexteditState by the worst-case storage which is (in bytes):\n//\n// [4 + 3 * sizeof(STB_TEXTEDIT_POSITIONTYPE)] * STB_TEXTEDIT_UNDOSTATECOUNT\n// + sizeof(STB_TEXTEDIT_CHARTYPE) * STB_TEXTEDIT_UNDOCHARCOUNT\n//\n//\n// Implementation mode:\n//\n// If you define STB_TEXTEDIT_IMPLEMENTATION before including this, it\n// will compile the implementation of the text edit widget, depending\n// on a large number of symbols which must be defined before the include.\n//\n// The implementation is defined only as static functions. You will then\n// need to provide your own APIs in the same file which will access the\n// static functions.\n//\n// The basic concept is that you provide a \"string\" object which\n// behaves like an array of characters. stb_textedit uses indices to\n// refer to positions in the string, implicitly representing positions\n// in the displayed textedit. This is true for both plain text and\n// rich text; even with rich text stb_truetype interacts with your\n// code as if there was an array of all the displayed characters.\n//\n// Symbols that must be the same in header-file and implementation mode:\n//\n// STB_TEXTEDIT_CHARTYPE the character type\n// STB_TEXTEDIT_POSITIONTYPE small type that is a valid cursor position\n// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow\n// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer\n//\n// Symbols you must define for implementation mode:\n//\n// STB_TEXTEDIT_STRING the type of object representing a string being edited,\n// typically this is a wrapper object with other data you need\n//\n// STB_TEXTEDIT_STRINGLEN(obj) the length of the string (ideally O(1))\n// STB_TEXTEDIT_LAYOUTROW(&r,obj,n) returns the results of laying out a line of characters\n// starting from character #n (see discussion below)\n// STB_TEXTEDIT_GETWIDTH(obj,n,i) returns the pixel delta from the xpos of the i'th character\n// to the xpos of the i+1'th char for a line of characters\n// starting at character #n (i.e. accounts for kerning\n// with previous char)\n// STB_TEXTEDIT_KEYTOTEXT(k) maps a keyboard input to an insertable character\n// (return type is int, -1 means not valid to insert)\n// (not supported if you want to use UTF-8, see below)\n// STB_TEXTEDIT_GETCHAR(obj,i) returns the i'th character of obj, 0-based\n// STB_TEXTEDIT_NEWLINE the character returned by _GETCHAR() we recognize\n// as manually wordwrapping for end-of-line positioning\n//\n// STB_TEXTEDIT_DELETECHARS(obj,i,n) delete n characters starting at i\n// STB_TEXTEDIT_INSERTCHARS(obj,i,c*,n) try to insert n characters at i (pointed to by STB_TEXTEDIT_CHARTYPE*)\n// returns number of characters actually inserted.

For example,\n// my Windows implementations add an additional CONTROL bit, and an additional KEYDOWN\n// bit. Then all of the STB_TEXTEDIT_K_ values bitwise-or in the KEYDOWN bit,\n// and I pass both WM_KEYDOWN and WM_CHAR events to the \"key\" function in the\n// API below.

STB_TEXTEDIT_KEYTYPE defaults to int, but you can #define it to\n// anything other type you want before including.\n// if the STB_TEXTEDIT_KEYTOTEXT function is defined, selected keys are\n// transformed into text and stb_textedit_text() is automatically called.\n//\n// text: (added 2025)\n// call this to directly send text input the textfield, which is required\n// for UTF-8 support, because stb_textedit_key() + STB_TEXTEDIT_KEYTOTEXT()\n// cannot infer text length.\n//\n//\n// When rendering, you can read the cursor position and selection state from\n// the STB_TexteditState.\n//\n//\n// Notes:\n//\n// This is designed to be usable in IMGUI, so it allows for the possibility of\n// running in an IMGUI that has NOT cached the multi-line layout. For this\n// reason, it provides an interface that is compatible with computing the\n// layout incrementally--we try to make sure we make as few passes through\n// as possible. (For example, to locate the mouse pointer in the text, we\n// could define functions that return the X and Y positions of characters\n// and binary search Y and then X, but if we're doing dynamic layout this\n// will run the layout algorithm many times, so instead we manually search\n// forward in one pass. Similar logic applies to e.g. up-arrow and\n// down-arrow movement.)\n//\n// If it's run in a widget that *has* cached the layout, then this is less\n// efficient, but it's not horrible on modern computers. But you wouldn't\n// want to edit million-line files with it.\n\n\n////////////////////////////////////////////////////////////////////////////\n////////////////////////////////////////////////////////////////////////////\n////\n//// Header-file mode\n////\n////\n\n#ifndef INCLUDE_IMSTB_TEXTEDIT_H\n#define INCLUDE_IMSTB_TEXTEDIT_H\n\n////////////////////////////////////////////////////////////////////////\n//\n// STB_TexteditState\n//\n// Definition of STB_TexteditState which you should store\n// per-textfield;

If\n// this turns out to be a problem, you can re-enable the old rasterizer with\n// #define STBTT_RASTERIZER_VERSION 1\n// which will incur about a 15% speed hit.\n//\n// ADDITIONAL DOCUMENTATION\n//\n// Immediately after this block comment are a series of sample programs.\n//\n// After the sample programs is the \"header file\" section. This section\n// includes documentation for each API function.\n//\n// Some important concepts to understand to use this library:\n//\n// Codepoint\n// Characters are defined by unicode codepoints, e.g. 65 is\n// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is\n// the hiragana for \"ma\".\n//\n// Glyph\n// A visual character shape (every codepoint is rendered as\n// some glyph)\n//\n// Glyph index\n// A font-specific integer ID representing a glyph\n//\n// Baseline\n// Glyph shapes are defined relative to a baseline, which is the\n// bottom of uppercase characters. Characters extend both above\n// and below the baseline.\n//\n// Current Point\n// As you draw text to the screen, you keep track of a \"current point\"\n// which is the origin of each character. The current point's vertical\n// position is the baseline. Even \"baked fonts\" use this model.\n//\n// Vertical Font Metrics\n// The vertical qualities of the font, used to vertically position\n// and space the characters. See docs for stbtt_GetFontVMetrics.\n//\n// Font Size in Pixels or Points\n// The preferred interface for specifying font sizes in stb_truetype\n// is to specify how tall the font's vertical extent should be in pixels.\n// If that sounds good enough, skip the next paragraph.\n//\n// Most font APIs instead use \"points\", which are a common typographic\n// measurement for describing font size, defined as 72 points per inch.\n// stb_truetype provides a point API for compatibility. However, true\n// \"per inch\" conventions don't make much sense on computer displays\n// since different monitors have different number of pixels per\n// inch. For example, Windows traditionally uses a convention that\n// there are 96 pixels per inch, thus making 'inch' measurements have\n// nothing to do with inches, and thus effectively defining a point to\n// be 1.333 pixels. Additionally, the TrueType font data provides\n// an explicit scale factor to scale a given font's glyphs to points,\n// but the author has observed that this scale factor is often wrong\n// for non-commercial fonts, thus making fonts scaled in points\n// according to the TrueType spec incoherently sized in practice.\n//\n// DETAILED USAGE:\n//\n// Scale:\n// Select how high you want the font to be, in points or pixels.\n// Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute\n// a scale factor SF that will be used by all other functions.\n//\n// Baseline:\n// You need to select a y-coordinate that is the baseline of where\n// your text will appear. Call GetFontBoundingBox to get the baseline-relative\n// bounding box for all characters. SF*-y0 will be the distance in pixels\n// that the worst-case character could extend above the baseline, so if\n// you want the top edge of characters to appear at the top of the\n// screen where y=0, then you would set the baseline to SF*-y0.\n//\n// Current point:\n// Set the current point where the first character will appear. The\n// first character could extend left of the current point; this is font\n// dependent. You can either choose a current point that is the leftmost\n// point and hope, or add some padding, or check the bounding box or\n// left-side-bearing of the first character to be displayed and set\n// the current point based on that.\n//\n// Displaying a character:\n// Compute the bounding box of the character. It will contain signed values\n// relative to . I.e. if it returns x0,y0,x1,y1,\n// then the character should be displayed in the rectangle from\n// to = 32 && *text < 128) {\n stbtt_aligned_quad q;\n stbtt_GetBakedQuad(cdata, 512,512, *text-32, &x,&y,&q,1);//1=opengl & d3d10+,0=d3d9\n glTexCoord2f(q.s0,q.t0); glVertex2f(q.x0,q.y0);\n glTexCoord2f(q.s1,q.t0); glVertex2f(q.x1,q.y0);\n glTexCoord2f(q.s1,q.t1); glVertex2f(q.x1,q.y1);\n glTexCoord2f(q.s0,q.t1); glVertex2f(q.x0,q.y1);\n }\n ++text;\n }\n glEnd();\n}\n#endif\n//\n//\n//////////////////////////////////////////////////////////////////////////////\n//\n// Complete program (this compiles): get a single bitmap, print as ASCII art\n//\n#if 0\n#include \n#define STB_TRUETYPE_IMPLEMENTATION // force following include to generate implementation\n#include \"stb_truetype.h\"\n\nchar ttf_buffer[1<<25];\n\nint main(int argc, char **argv)\n{\n stbtt_fontinfo font;\n unsigned char *bitmap;\n int w,h,i,j,c = (argc > 1 ? atoi(argv[1]) : 'a'), s = (argc > 2 ? atoi(argv[2]) : 20);\n\n fread(ttf_buffer, 1, 1<<25, fopen(argc > 3 ? argv[3] : \"c:/windows/fonts/arialbd.ttf\", \"rb\"));\n\n stbtt_InitFont(&font, ttf_buffer, stbtt_GetFontOffsetForIndex(ttf_buffer,0));\n bitmap = stbtt_GetCodepointBitmap(&font, 0,stbtt_ScaleForPixelHeight(&font, s), c, &w, &h, 0,0);\n\n for (j=0; j < h; ++j) {\n for (i=0; i < w; ++i)\n putchar(\" .:ioVM@\"[bitmap[j*w+i]>>5]);\n putchar('\\n');\n }\n return 0;\n}\n#endif\n//\n// Output:\n//\n// .ii.\n// @@@@@@.\n// V@Mio@@o\n// :i.

We try to make the breakage minor and easy to fix.\nBelow is a change-log of API breaking changes only. If you are using one of the functions listed, expect to have to fix some code.\nWhen you are not sure about a old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all implot files.\nYou can read releases logs https://github.com/epezent/implot/releases for more details.\n\n- 2023/08/20 (0.17) - ImPlotFlags_NoChild was removed as child windows are no longer needed to capture scroll. You can safely remove this flag if you were using it.\n- 2023/06/26 (0.15) - Various build fixes related to updates in Dear ImGui internals.\n- 2022/11/25 (0.15) - Make PlotText honor ImPlotItemFlags_NoFit.\n- 2022/06/19 (0.14) - The signature of ColormapScale has changed to accommodate a new ImPlotColormapScaleFlags parameter\n- 2022/06/17 (0.14) - **IMPORTANT** All PlotX functions now take an ImPlotX_Flags `flags` parameter. Where applicable, it is located before the existing `offset` and `stride` parameters.\n If you were providing offset and stride values, you will need to update your function call to include a `flags` value. If you fail to do this, you will likely see\n unexpected results or crashes without a compiler warning since these three are all default args. We apologize for the inconvenience, but this was a necessary evil.\n - PlotBarsH has been removed; use PlotBars + ImPlotBarsFlags_Horizontal instead\n - PlotErrorBarsH has been removed; use PlotErrorBars + ImPlotErrorBarsFlags_Horizontal\n - PlotHistogram/PlotHistogram2D signatures changed; `cumulative`, `density`, and `outliers` options now specified via ImPlotHistogramFlags\n - PlotPieChart signature changed; `normalize` option now specified via ImPlotPieChartFlags\n - PlotText signature changes; `vertical` option now specified via `ImPlotTextFlags_Vertical`\n - `PlotVLines` and `PlotHLines` replaced with `PlotInfLines` (+ ImPlotInfLinesFlags_Horizontal )\n - arguments of ImPlotGetter have been reversed to be consistent with other API callbacks\n - SetupAxisScale + ImPlotScale have replaced ImPlotAxisFlags_LogScale and ImPlotAxisFlags_Time flags\n - ImPlotFormatters should now return an int indicating the size written\n - the signature of ImPlotGetter has been reversed so that void* user_data is the last argument and consistent with other callbacks\n- 2021/10/19 (0.13) - MAJOR API OVERHAUL! See #168 and #272\n - TRIVIAL RENAME:\n - ImPlotLimits -> ImPlotRect\n - ImPlotYAxis_ -> ImAxis_\n - SetPlotYAxis -> SetAxis\n - BeginDragDropTarget -> BeginDragDropTargetPlot\n - BeginDragDropSource -> BeginDragDropSourcePlot\n - ImPlotFlags_NoMousePos -> ImPlotFlags_NoMouseText\n - SetNextPlotLimits -> SetNextAxesLimits\n - SetMouseTextLocation -> SetupMouseText\n - SIGNATURE MODIFIED:\n - PixelsToPlot/PlotToPixels -> added optional X-Axis arg\n - GetPlotMousePos -> added optional X-Axis arg\n - GetPlotLimits -> added optional X-Axis arg\n - GetPlotSelection -> added optional X-Axis arg\n - DragLineX/Y/DragPoint -> now takes int id; removed labels (render with Annotation/Tag instead)\n - REPLACED:\n - IsPlotXAxisHovered/IsPlotXYAxisHovered -> IsAxisHovered(ImAxis)\n - BeginDragDropTargetX/BeginDragDropTargetY -> BeginDragDropTargetAxis(ImAxis)\n - BeginDragDropSourceX/BeginDragDropSourceY -> BeginDragDropSourceAxis(ImAxis)\n - ImPlotCol_XAxis, ImPlotCol_YAxis1, etc. -> ImPlotCol_AxisText (push/pop this around SetupAxis to style individual axes)\n - ImPlotCol_XAxisGrid, ImPlotCol_Y1AxisGrid -> ImPlotCol_AxisGrid (push/pop this around SetupAxis to style individual axes)\n - SetNextPlotLimitsX/Y -> SetNextAxisLimits(ImAxis)\n - LinkNextPlotLimits -> SetNextAxisLinks(ImAxis)\n - FitNextPlotAxes -> SetNextAxisToFit(ImAxis)/SetNextAxesToFit\n - SetLegendLocation -> SetupLegend\n - ImPlotFlags_NoHighlight -> ImPlotLegendFlags_NoHighlight\n - ImPlotOrientation -> ImPlotLegendFlags_Horizontal\n - Annotate -> Annotation\n - REMOVED:\n - GetPlotQuery, SetPlotQuery, IsPlotQueried -> use DragRect\n - SetNextPlotTicksX, SetNextPlotTicksY -> use SetupAxisTicks\n - SetNextPlotFormatX, SetNextPlotFormatY -> use SetupAxisFormat\n - AnnotateClamped -> use Annotation(bool clamp = true)\n - OBSOLETED:\n - BeginPlot (original signature) -> use simplified signature + Setup API\n- 2021/07/30 (0.12) - The offset argument of `PlotXG` functions was been removed. Implement offsetting in your getter callback instead.\n- 2021/03/08 (0.9) - SetColormap and PushColormap(ImVec4*) were removed. Use AddColormap for custom colormap support. LerpColormap was changed to SampleColormap.\n ShowColormapScale was changed to ColormapScale and requires additional arguments.\n- 2021/03/07 (0.9) - The signature of ShowColormapScale was modified to accept a ImVec2 size.\n- 2021/02/28 (0.9) - BeginLegendDragDropSource was changed to BeginDragDropSourceItem with a number of other drag and drop improvements.\n- 2021/01/18 (0.9) - The default behavior for opening context menus was change from double right-click to single right-click. ImPlotInputMap and related functions were moved\n to implot_internal.h due to its immaturity.\n- 2020/10/16 (0.8) - ImPlotStyleVar_InfoPadding was changed to ImPlotStyleVar_MousePosPadding\n- 2020/09/10 (0.8) - The single array versions of PlotLine, PlotScatter, PlotStems, and PlotShaded were given additional arguments for x-scale and x0.\n- 2020/09/07 (0.8) - Plotting functions which accept a custom getter function pointer have been post-fixed with a G (e.g. PlotLineG)\n- 2020/09/06 (0.7) - Several flags under ImPlotFlags and ImPlotAxisFlags were inverted (e.g. ImPlotFlags_Legend -> ImPlotFlags_NoLegend) so that the default flagset\n is simply 0. This more closely matches ImGui's style and makes it easier to enable non-default but commonly used flags (e.g. ImPlotAxisFlags_Time).\n- 2020/08/28 (0.5) - ImPlotMarker_ can no longer be combined with bitwise OR, |. This features caused unecessary slow-down, and almost no one used it.\n- 2020/08/25 (0.5) - ImPlotAxisFlags_Scientific was removed. Logarithmic axes automatically uses scientific notation.\n- 2020/08/17 (0.5) - PlotText was changed so that text is centered horizontally and vertically about the desired point.\n- 2020/08/16 (0.5) - An ImPlotContext must be explicitly created and destroyed now with `CreateContext` and `DestroyContext`. Previously, the context was statically initialized in this source file.\n- 2020/06/13 (0.4) - The flags `ImPlotAxisFlag_Adaptive` and `ImPlotFlags_Cull` were removed. Both are now done internally by default.\n- 2020/06/03 (0.3) - The signature and behavior of PlotPieChart was changed so that data with sum less than 1 can optionally be normalized. The label format can now be specified as well.\n- 2020/06/01 (0.3) - SetPalette was changed to `SetColormap` for consistency with other plotting libraries. `RestorePalette` was removed. Use `SetColormap(ImPlotColormap_Default)`.\n- 2020/05/31 (0.3) - Plot functions taking custom ImVec2* getters were removed. Use the ImPlotPoint* getter versions instead.\n- 2020/05/29 (0.3) - The signature of ImPlotLimits::Contains was changed to take two doubles instead of ImVec2\n- 2020/05/16 (0.2) - All plotting functions were reverted to being prefixed with \"Plot\" to maintain a consistent VerbNoun style. `Plot` was split into `PlotLine`\n and `PlotScatter` (however, `PlotLine` can still be used to plot scatter points as `Plot` did before.). `Bar` is not `PlotBars`, to indicate\n that multiple bars will be plotted.\n- 2020/05/13 (0.2) - `ImMarker` was change to `ImPlotMarker` and `ImAxisFlags` was changed to `ImPlotAxisFlags`.\n- 2020/05/11 (0.2) - `ImPlotFlags_Selection` was changed to `ImPlotFlags_BoxSelect`\n- 2020/05/11 (0.2) - The namespace ImGui:: was replaced with ImPlot::. As a result, the following additional changes were made:\n - Functions that were prefixed or decorated with the word \"Plot\" have been truncated. E.g., `ImGui::PlotBars` is now just `ImPlot::Bar`.\n It should be fairly obvious what was what.\n - Some functions have been given names that would have otherwise collided with the ImGui namespace. This has been done to maintain a consistent\n style with ImGui. E.g., 'ImGui::PushPlotStyleVar` is now 'ImPlot::PushStyleVar'.\n- 2020/05/10 (0.2) - The following function/struct names were changes:\n - ImPlotRange -> ImPlotLimits\n - GetPlotRange() -> GetPlotLimits()\n - SetNextPlotRange -> SetNextPlotLimits\n - SetNextPlotRangeX -> SetNextPlotLimitsX\n - SetNextPlotRangeY -> SetNextPlotLimitsY\n- 2020/05/10 (0.2) - Plot queries are pixel based by default. Query rects that maintain relative plot position have been removed. This was done to support multi-y-axis.\n\n*/\n\n#ifndef IMGUI_DEFINE_MATH_OPERATORS\n#define IMGUI_DEFINE_MATH_OPERATORS\n#endif\n#include \"implot.h\"\n#ifndef IMGUI_DISABLE\n#include \"implot_internal.h\"\n\n#include \n\n// Support for pre-1.82 versions.

The behavior of this color depends upon the style color to\n// which it as applied:\n//\n// 1) For style colors associated with plot items (e.g. ImPlotCol_Line),\n// IMPLOT_AUTO_COL tells ImPlot to color the item with the next unused\n// color in the current colormap. Thus, every item will have a different\n// color up to the number of colors in the colormap, at which point the\n// colormap will roll over. For most use cases, you should not need to\n// set these style colors to anything but IMPLOT_COL_AUTO; you are\n// probably better off changing the current colormap. However, if you\n// need to explicitly color a particular item you may either Push/Pop\n// the style color around the item in question, or use the SetNextXXXStyle\n// API below.

Of course, you are free to\n// manually set these colors to whatever you like, and further can Push/Pop\n// them around individual plots for plot-specific styling (e.g. coloring axes).\n\n// Provides access to plot style structure for permanant modifications to colors, sizes, etc.\nIMPLOT_API ImPlotStyle& GetStyle();\n\n// Style plot colors for current ImGui style (default).\nIMPLOT_API void StyleColorsAuto(ImPlotStyle* dst = nullptr);\n// Style plot colors for ImGui \"Classic\".\nIMPLOT_API void StyleColorsClassic(ImPlotStyle* dst = nullptr);\n// Style plot colors for ImGui \"Dark\".\nIMPLOT_API void StyleColorsDark(ImPlotStyle* dst = nullptr);\n// Style plot colors for ImGui \"Light\".\nIMPLOT_API void StyleColorsLight(ImPlotStyle* dst = nullptr);\n\n// Use PushStyleX to temporarily modify your ImPlotStyle.
