Some of the current weaknesses includes:\n\n - Doesn't look fancy, doesn't animate.\n - Limited layout features, intricate layouts are typically crafted in code.\n\n\n END-USER GUIDE\n ==============\n\n - Double-click on title bar to collapse window.\n - Click upper right corner to close a window, available when 'bool* p_open' is passed to ImGui::Begin().\n - Click and drag on lower right corner to resize window (double-click to auto fit window to its contents).\n - Click and drag on any empty space to move window.\n - TAB/SHIFT+TAB to cycle through keyboard editable fields.\n - CTRL+Click on a slider or drag box to input value as text.\n - Use mouse wheel to scroll.\n - Text editor:\n - Hold SHIFT or use mouse to select text.\n - CTRL+Left/Right to word jump.\n - CTRL+Shift+Left/Right to select words.\n - CTRL+A our Double-Click to select all.\n - CTRL+X,CTRL+C,CTRL+V to use OS clipboard/\n - CTRL+Z,CTRL+Y to undo/redo.\n - ESCAPE to revert text to its original value.\n - You can apply arithmetic operators +,*,/ on numerical values. Use +- to subtract (because - would set a negative value!)\n - Controls are automatically adjusted for OSX to match standard OSX text editing operations.\n - General Keyboard controls: enable with ImGuiConfigFlags_NavEnableKeyboard.\n - General Gamepad controls: enable with ImGuiConfigFlags_NavEnableGamepad. See suggested mappings in imgui.h ImGuiNavInput_ + download PNG/PSD at http://dearimgui.org/controls_sheets\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, if your code doesn't run the UI is gone! The UI can be highly dynamic, there are no construction or\n destruction steps, less superfluous 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 - 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 - This codebase is also optimized to yield decent performances with typical \"Debug\" builds settings.\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 - C++: this is a very C-ish codebase: we don't rely on C++11, we don't include any C++ headers, and ImGui:: is a namespace.\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 However, imgui_internal.h can optionally export math operators for ImVec2/ImVec4, which we use in this codebase.\n - C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction (avoid using it in your code!).\n\n\n HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI\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 - 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 EXHIBIT 1: 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 screen\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 EXHIBIT 2: IMPLEMENTING CUSTOM BACKEND / CUSTOM ENGINE\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 // Build and load the texture atlas into a texture\n // (In the examples/ app this is usually done within the ImGui_ImplXXX_Init() function from one of the demo Renderer)\n int width, height;\n unsigned char* pixels = NULL;\n io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height);\n\n // At this point you've got the texture data and you need to upload that to your graphic system:\n // After we have created the texture, store its pointer/identifier (_in whichever format your engine uses_) in 'io.Fonts->TexID'.\n // This will be passed back to your via the renderer. Basically ImTextureID == void*. Read FAQ for details about ImTextureID.\n MyTexture* texture = MyEngine::CreateTextureFromMemoryPixels(pixels, width, height, TEXTURE_TYPE_RGBA32)\n io.Fonts->SetTexID((void*)texture);\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.MousePos = my_mouse_pos; // set the mouse position\n io.MouseDown[0] = my_mouse_buttons[0]; // set the mouse button states\n io.MouseDown[1] = my_mouse_buttons[1];\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 // Render dear imgui, swap buffers\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();\n ImGui::Render();\n ImDrawData* draw_data = ImGui::GetDrawData();\n MyImGuiRenderFunction(draw_data);\n SwapBuffers();\n }\n\n // 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 and example applications for details about this!\n\n\n HOW A SIMPLE RENDERING FUNCTION MAY LOOK LIKE\n ---------------------------------------------\n The backends in impl_impl_XXX.cpp files contain many working implementations of a rendering function.\n\n void void MyImGuiRenderFunction(ImDrawData* draw_data)\n {\n // TODO: Setup render state: alpha-blending enabled, no face culling, no depth testing, scissor enabled\n // TODO: Setup viewport covering draw_data->DisplayPos to draw_data->DisplayPos + draw_data->DisplaySize\n // TODO: Setup orthographic projection matrix cover draw_data->DisplayPos to draw_data->DisplayPos + draw_data->DisplaySize\n // TODO: Setup shader: vertex { float2 pos, float2 uv, u32 color }, fragment shader sample color from 1 texture, multiply by vertex color.\n for (int n = 0; n < draw_data->CmdListsCount; n++)\n {\n const ImDrawList* cmd_list = draw_data->CmdLists[n];\n const ImDrawVert* vtx_buffer = cmd_list->VtxBuffer.Data; // vertex buffer generated by Dear ImGui\n const ImDrawIdx* idx_buffer = cmd_list->IdxBuffer.Data; // index buffer generated by Dear ImGui\n for (int cmd_i = 0; cmd_i < cmd_list->CmdBuffer.Size; cmd_i++)\n {\n const ImDrawCmd* pcmd = &cmd_list->CmdBuffer[cmd_i];\n if (pcmd->UserCallback)\n {\n pcmd->UserCallback(cmd_list, pcmd);\n }\n else\n {\n // The texture for the draw call is specified by pcmd->GetTexID().\n // The vast majority of draw calls will use the Dear ImGui texture atlas, which value you have set yourself during initialization.\n MyEngineBindTexture((MyTexture*)pcmd->GetTexID());\n\n // We are using scissoring to clip some objects. All low-level graphics API should support it.\n // - If your engine doesn't support scissoring yet, you may ignore this at first. You will get some small glitches\n // (some elements visible outside their bounds) but you can fix that once everything else works!\n // - Clipping coordinates are provided in imgui coordinates space:\n // - For a given viewport, draw_data->DisplayPos == viewport->Pos and draw_data->DisplaySize == viewport->Size\n // - In a single viewport application, draw_data->DisplayPos == (0,0) and draw_data->DisplaySize == io.DisplaySize, but always use GetMainViewport()->Pos/Size instead of hardcoding those values.\n // - In the interest of supporting multi-viewport applications (see 'docking' branch on github),\n // always subtract draw_data->DisplayPos from clipping bounds to convert them to your viewport space.\n // - Note that pcmd->ClipRect contains Min+Max bounds. Some graphics API may use Min+Max, other may use Min+Size (size being Max-Min)\n ImVec2 pos = draw_data->DisplayPos;\n MyEngineScissor((int)(pcmd->ClipRect.x - pos.x), (int)(pcmd->ClipRect.y - pos.y), (int)(pcmd->ClipRect.z - pos.x), (int)(pcmd->ClipRect.w - pos.y));\n\n // Render 'pcmd->ElemCount/3' indexed triangles.\n // By default the indices ImDrawIdx are 16-bit, you can change them to 32-bit in imconfig.h if your engine doesn't support 16-bit indices.\n MyEngineDrawIndexedTriangles(pcmd->ElemCount, sizeof(ImDrawIdx) == 2 ? GL_UNSIGNED_SHORT : GL_UNSIGNED_INT, idx_buffer, vtx_buffer);\n }\n idx_buffer += pcmd->ElemCount;\n }\n }\n }\n\n\n USING GAMEPAD/KEYBOARD NAVIGATION CONTROLS\n ------------------------------------------\n - The gamepad/keyboard navigation is fairly functional and keeps being improved.\n - Gamepad support is particularly useful to use Dear ImGui on a console system (e.g. PS4, Switch, XB1) without a mouse!\n - You can ask questions and report issues at https://github.com/ocornut/imgui/issues/787\n - The initial focus was to support game controllers, but keyboard is becoming increasingly and decently usable.\n - Keyboard:\n - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard to enable.\n NewFrame() will automatically fill io.NavInputs[] based on your io.KeysDown[] + io.KeyMap[] arrays.\n - When keyboard navigation is active (io.NavActive + ImGuiConfigFlags_NavEnableKeyboard), the io.WantCaptureKeyboard flag\n will be set. For more advanced uses, you may want to read from:\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 (and usually goes false when mouse is used).\n - or query focus information with e.g. IsWindowFocused(ImGuiFocusedFlags_AnyWindow), IsItemFocused() etc. functions.\n Please reach out if you think the game vs navigation input sharing could be improved.\n - Gamepad:\n - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable.\n - Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + fill the io.NavInputs[] fields before calling NewFrame().\n Note that io.NavInputs[] is cleared by EndFrame().\n - See 'enum ImGuiNavInput_' in imgui.h for a description of inputs. For each entry of io.NavInputs[], set the following values:\n 0.0f= not held. 1.0f= fully held. Pass intermediate 0.0f..1.0f values for analog triggers/sticks.\n - We use a simple >0.0f test for activation testing, and won't attempt to test for a dead-zone.\n Your 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 - You can download PNG/PSD files depicting the gamepad controls for common controllers at: http://dearimgui.org/controls_sheets\n - If you need to share inputs between your game and the imgui parts, the easiest approach is to go all-or-nothing, with a buttons combo\n to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved.\n - Mouse:\n - PS4 users: Consider emulating a mouse cursor with DualShock4 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) + uSynergy.c (on your console/tablet/phone app) to share your PC mouse/keyboard.\n - On a TV/console system where readability may be lower or mouse inputs may be awkward, you may want to set the ImGuiConfigFlags_NavEnableSetMousePos flag.\n Enabling ImGuiConfigFlags_NavEnableSetMousePos + 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, imgui will misbehave as it will see your mouse moving back and 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 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 - 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 explicily 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.

Have the ImGui::ShowDemoWindow() function wired in an always-available\n// debug menu of your game/app! Removing this file from your project is hindering access to documentation for everyone\n// in your team, 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// Message to beginner C/C++ programmers about the meaning of the 'static' keyword:\n// In this demo code, we frequently use 'static' variables inside functions. A static variable persists across calls,\n// so it is essentially like a global variable but declared inside the scope of the function. We do this as a way to\n// gather code and data in the same place, to make the demo source code faster to read, faster to write, and smaller\n// in size. It also happens to be 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. This might be a pattern you will want to use in your code,\n// but most of the real data you would be editing is likely going to be stored outside your functions.\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_internal.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 IDE: CTRL+comma (\"Edit.NavigateTo\") can follow symbols in comments, whereas CTRL+F12 (\"Edit.GoToImplementation\") cannot.\n// - With Visual Assist installed: ALT+G (\"VAssistX.GoToImplementation\") can also follow symbols in comments.\n\n/*\n\nIndex of this file:\n\n// [SECTION] Forward Declarations, Helpers\n// [SECTION] Demo Window / ShowDemoWindow()\n// - sub section: ShowDemoWindowWidgets()\n// - sub section: ShowDemoWindowLayout()\n// - sub section: ShowDemoWindowPopups()\n// - sub section: ShowDemoWindowTables()\n// - sub section: ShowDemoWindowMisc()\n// [SECTION] About Window / ShowAboutWindow()\n// [SECTION] Style Editor / ShowStyleEditor()\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: Documents Handling / ShowExampleAppDocuments()\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#if defined(_MSC_VER) && _MSC_VER <= 1500 // MSVC 2008 or earlier\n#include // intptr_t\n#else\n#include // intptr_t\n#endif\n\n// Visual Studio warnings\n#ifdef _MSC_VER\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 a 8 byte value.

Read the FAQ about ImTextureID!\n// [X] Renderer: Support for large meshes (64k+ vertices) with 16-bit indices.\n\n// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.\n// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.\n// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.\n// Read online: https://github.com/ocornut/imgui/tree/master/docs\n\n// CHANGELOG\n// (minor and older changes stripped away, please see git history for details)\n// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).\n// 2021-05-19: DirectX11: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)\n// 2021-02-18: DirectX11: Change blending equation to preserve alpha in output buffer.\n// 2019-08-01: DirectX11: Fixed code querying the Geometry Shader state (would generally error with Debug layer enabled).\n// 2019-07-21: DirectX11: Backup, clear and restore Geometry Shader is any is bound when calling ImGui_ImplDX10_RenderDrawData. Clearing Hull/Domain/Compute shaders without backup/restore.\n// 2019-05-29: DirectX11: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.\n// 2019-04-30: DirectX11: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.\n// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().\n// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.\n// 2018-08-01: DirectX11: Querying for IDXGIFactory instead of IDXGIFactory1 to increase compatibility.\n// 2018-07-13: DirectX11: Fixed unreleased resources in Init and Shutdown functions.\n// 2018-06-08: Misc: Extracted imgui_impl_dx11.cpp/.h away from the old combined DX11+Win32 example.\n// 2018-06-08: DirectX11: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.\n// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX11_RenderDrawData() in the .h file so you can call it yourself.\n// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.\n// 2016-05-07: DirectX11: Disabling depth-write.\n\n#include \"imgui.h\"\n#include \"imgui_impl_dx11.h\"\n\n// DirectX\n#include \n#include \n#include \n#ifdef _MSC_VER\n#pragma comment(lib, \"d3dcompiler\") // Automatically link with d3dcompiler.lib as we are using D3DCompile() below.\n#endif\n\n// DirectX11 data\nstruct ImGui_ImplDX11_Data\n{\n ID3D11Device* pd3dDevice;\n ID3D11DeviceContext* pd3dDeviceContext;\n IDXGIFactory* pFactory;\n ID3D11Buffer* pVB;\n ID3D11Buffer* pIB;\n ID3D11VertexShader* pVertexShader;\n ID3D11InputLayout* pInputLayout;\n ID3D11Buffer* pVertexConstantBuffer;\n ID3D11PixelShader* pPixelShader;\n ID3D11SamplerState* pFontSampler;\n ID3D11ShaderResourceView* pFontTextureView;\n ID3D11RasterizerState* pRasterizerState;\n ID3D11BlendState* pBlendState;\n ID3D11DepthStencilState* pDepthStencilState;\n int VertexBufferSize;\n int IndexBufferSize;\n\n ImGui_ImplDX11_Data() { memset(this, 0, sizeof(*this)); VertexBufferSize = 5000; IndexBufferSize = 10000; }\n};\n\nstruct VERTEX_CONSTANT_BUFFER\n{\n float mvp[4][4];\n};\n\n// Backend data stored in io.BackendRendererUserData to allow support for multiple Dear ImGui contexts\n// It is STRONGLY preferred that you use docking branch with multi-viewports (== single Dear ImGui context + multiple windows) instead of multiple Dear ImGui contexts.\nstatic ImGui_ImplDX11_Data* ImGui_ImplDX11_GetBackendData()\n{\n return ImGui::GetCurrentContext() ?

Commentary\n//-----------------------------------------------------------------------------\n\n//-----------------------------------------------------------------------------\n// Typical tables call flow: (root level is generally public API):\n//-----------------------------------------------------------------------------\n// - BeginTable() user begin into a table\n// | BeginChild() - (if ScrollX/ScrollY is set)\n// | TableBeginInitMemory() - first time table is used\n// | TableResetSettings() - on settings reset\n// | TableLoadSettings() - on settings load\n// | TableBeginApplyRequests() - apply queued resizing/reordering/hiding requests\n// | - TableSetColumnWidth() - apply resizing width (for mouse resize, often requested by previous frame)\n// | - TableUpdateColumnsWeightFromWidth()- recompute columns weights (of stretch columns) from their respective width\n// - TableSetupColumn() user submit columns details (optional)\n// - TableSetupScrollFreeze() user submit scroll freeze information (optional)\n//-----------------------------------------------------------------------------\n// - TableUpdateLayout() [Internal] followup to BeginTable(): setup everything: widths, columns positions, clipping rectangles. Automatically called by the FIRST call to TableNextRow() or TableHeadersRow().\n// | TableSetupDrawChannels() - setup ImDrawList channels\n// | TableUpdateBorders() - detect hovering columns for resize, ahead of contents submission\n// | TableDrawContextMenu() - draw right-click context menu\n//-----------------------------------------------------------------------------\n// - TableHeadersRow() or TableHeader() user submit a headers row (optional)\n// | TableSortSpecsClickColumn() - when left-clicked: alter sort order and sort direction\n// | TableOpenContextMenu() - when right-clicked: trigger opening of the default context menu\n// - TableGetSortSpecs() user queries updated sort specs (optional, generally after submitting headers)\n// - TableNextRow() user begin into a new row (also automatically called by TableHeadersRow())\n// | TableEndRow() - finish existing row\n// | TableBeginRow() - add a new row\n// - TableSetColumnIndex() / TableNextColumn() user begin into a cell\n// | TableEndCell() - close existing column/cell\n// | TableBeginCell() - enter into current column/cell\n// - [...] user emit contents\n//-----------------------------------------------------------------------------\n// - EndTable() user ends the table\n// | TableDrawBorders() - draw outer borders, inner vertical borders\n// | TableMergeDrawChannels() - merge draw channels if clipping isn't required\n// | EndChild() - (if ScrollX/ScrollY is set)\n//-----------------------------------------------------------------------------\n\n//-----------------------------------------------------------------------------\n// TABLE SIZING\n//-----------------------------------------------------------------------------\n// (Read carefully because this is subtle but it does make sense!)\n//-----------------------------------------------------------------------------\n// About 'outer_size':\n// Its meaning needs to differ slightly depending on if we are using ScrollX/ScrollY flags.\n// Default value is ImVec2(0.0f, 0.0f).\n// X\n// - outer_size.x <= 0.0f -> Right-align from window/work-rect right-most edge. With -FLT_MIN or 0.0f will align exactly on right-most edge.\n// - outer_size.x > 0.0f -> Set Fixed width.\n// Y with ScrollX/ScrollY disabled: we output table directly in current window\n// - outer_size.y < 0.0f -> Bottom-align (but will auto extend, unless _NoHostExtendY is set). Not meaningful is 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 _NoHostExtenY is set)\n// Y with ScrollX/ScrollY enabled: using a child window for scrolling\n// - outer_size.y < 0.0f -> Bottom-align. Not meaningful is parent window can vertically scroll.\n// - outer_size.y = 0.0f -> Bottom-align, consistent with BeginChild(). Not recommended unless table is last item in parent window.\n// - outer_size.y > 0.0f -> Set Exact height. Recommended when using Scrolling on any axis.\n//-----------------------------------------------------------------------------\n// Outer size is also affected by the NoHostExtendX/NoHostExtendY flags.\n// Important to that 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 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//-----------------------------------------------------------------------------\n// About overriding column sizing policy and width/weight with TableSetupColumn():\n// We use a default parameter of 'init_width_or_weight == -1'.\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 full padding.\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 weight/widths.\n//-----------------------------------------------------------------------------\n// About using column width:\n// If a column is manual 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 only submit 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() return 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#include \"imgui.h\"\n#ifndef IMGUI_DISABLE\n\n#ifndef IMGUI_DEFINE_MATH_OPERATORS\n#define IMGUI_DEFINE_MATH_OPERATORS\n#endif\n#include \"imgui_internal.h\"\n\n// System includes\n#if defined(_MSC_VER) && _MSC_VER <= 1500 // MSVC 2008 or earlier\n#include // intptr_t\n#else\n#include // intptr_t\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#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_UNDOSTATE_COUNT\n// + sizeof(STB_TEXTEDIT_CHARTYPE) * STB_TEXTEDIT_UNDOCHAR_COUNT\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// 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) insert n characters at i (pointed to by STB_TEXTEDIT_CHARTYPE*)\n//\n// STB_TEXTEDIT_K_SHIFT a power of two that is or'd in to a keyboard input to represent the shift key\n//\n// STB_TEXTEDIT_K_LEFT keyboard input to move cursor left\n// STB_TEXTEDIT_K_RIGHT keyboard input to move cursor right\n// STB_TEXTEDIT_K_UP keyboard input to move cursor up\n// STB_TEXTEDIT_K_DOWN keyboard input to move cursor down\n// STB_TEXTEDIT_K_PGUP keyboard input to move cursor up a page\n// STB_TEXTEDIT_K_PGDOWN keyboard input to move cursor down a page\n// STB_TEXTEDIT_K_LINESTART keyboard input to move cursor to start of line // e.g. HOME\n// STB_TEXTEDIT_K_LINEEND keyboard input to move cursor to end of line // e.g. END\n// STB_TEXTEDIT_K_TEXTSTART keyboard input to move cursor to start of text // e.g. ctrl-HOME\n// STB_TEXTEDIT_K_TEXTEND keyboard input to move cursor to end of text // e.g. ctrl-END\n// STB_TEXTEDIT_K_DELETE keyboard input to delete selection or character under cursor\n// STB_TEXTEDIT_K_BACKSPACE keyboard input to delete selection or character left of cursor\n// STB_TEXTEDIT_K_UNDO keyboard input to perform undo\n// STB_TEXTEDIT_K_REDO keyboard input to perform redo\n//\n// Optional:\n// STB_TEXTEDIT_K_INSERT keyboard input to toggle insert mode\n// STB_TEXTEDIT_IS_SPACE(ch) true if character is whitespace (e.g. 'isspace'),\n// required for default WORDLEFT/WORDRIGHT handlers\n// STB_TEXTEDIT_MOVEWORDLEFT(obj,i) custom handler for WORDLEFT, returns index to move cursor to\n// STB_TEXTEDIT_MOVEWORDRIGHT(obj,i) custom handler for WORDRIGHT, returns index to move cursor to\n// STB_TEXTEDIT_K_WORDLEFT keyboard input to move cursor left one word // e.g. ctrl-LEFT\n// STB_TEXTEDIT_K_WORDRIGHT keyboard input to move cursor right one word // e.g. ctrl-RIGHT\n// STB_TEXTEDIT_K_LINESTART2 secondary keyboard input to move cursor to start of line\n// STB_TEXTEDIT_K_LINEEND2 secondary keyboard input to move cursor to end of line\n// STB_TEXTEDIT_K_TEXTSTART2 secondary keyboard input to move cursor to start of text\n// STB_TEXTEDIT_K_TEXTEND2 secondary keyboard input to move cursor to end of text\n//\n// Keyboard input must be encoded as a single integer value; e.g. a character code\n// and some bitflags that represent shift states. to simplify the interface, SHIFT must\n// be a bitflag, so we can test the shifted state of cursor movements to allow selection,\n// i.e. (STB_TEXTEDIT_K_RIGHT|STB_TEXTEDIT_K_SHIFT) should be shifted right-arrow.\n//\n// You can encode other things, such as CONTROL or ALT, in additional bits, and\n// then test for their presence in e.g. STB_TEXTEDIT_K_WORDLEFT. 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. The control keys will only match WM_KEYDOWN events because of the\n// keydown bit I add, and STB_TEXTEDIT_KEYTOTEXT only tests for the KEYDOWN\n// bit so it only decodes WM_CHAR events.\n//\n// STB_TEXTEDIT_LAYOUTROW returns information about the shape of one displayed\n// row of characters assuming they start on the i'th character--the width and\n// the height and the number of characters consumed. This allows this library\n// to traverse the entire layout incrementally. You need to compute word-wrapping\n// here.\n//\n// Each textfield keeps its own insert mode state, which is not how normal\n// applications work. To keep an app-wide insert mode, update/copy the\n// \"insert_mode\" field of STB_TexteditState before/after calling API functions.\n//\n// API\n//\n// void stb_textedit_initialize_state(STB_TexteditState *state, int is_single_line)\n//\n// void stb_textedit_click(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, float x, float y)\n// void stb_textedit_drag(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, float x, float y)\n// int stb_textedit_cut(STB_TEXTEDIT_STRING *str, STB_TexteditState *state)\n// int stb_textedit_paste(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, STB_TEXTEDIT_CHARTYPE *text, int len)\n// void stb_textedit_key(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, STB_TEXEDIT_KEYTYPE key)\n//\n// Each of these functions potentially updates the string and updates the\n// state.\n//\n// initialize_state:\n// set the textedit state to a known good default state when initially\n// constructing the textedit.\n//\n// click:\n// call this with the mouse x,y on a mouse down; it will update the cursor\n// and reset the selection start/end to the cursor point. the x,y must\n// be relative to the text widget, with (0,0) being the top left.\n//\n// drag:\n// call this with the mouse x,y on a mouse drag/up; it will update the\n// cursor and the selection end point\n//\n// cut:\n// call this to delete the current selection; returns true if there was\n// one. you should FIRST copy the current selection to the system paste buffer.\n// (To copy, just copy the current selection out of the string yourself.)\n//\n// paste:\n// call this to paste text at the current cursor point or over the current\n// selection if there is one.\n//\n// key:\n// call this for keyboard inputs sent to the textfield. you can use it\n// for \"key down\" events or for \"translated\" key events. if you need to\n// do both (as in Win32), or distinguish Unicode characters from control\n// inputs, set a high bit to distinguish the two; then you can define the\n// various definitions like STB_TEXTEDIT_K_LEFT have the is-key-event bit\n// set, and make STB_TEXTEDIT_KEYTOCHAR check that the is-key-event bit is\n// clear. STB_TEXTEDIT_KEYTYPE defaults to int, but you can #define it to\n// anything other type you wante before including.\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_STB_TEXTEDIT_H\n#define INCLUDE_STB_TEXTEDIT_H\n\n////////////////////////////////////////////////////////////////////////\n//\n// STB_TexteditState\n//\n// Definition of STB_TexteditState which you should store\n// per-textfield;

The new rasterizer more\n// accurately measures pixel coverage for anti-aliasing, except in the case\n// where multiple shapes overlap, in which case it overestimates the AA pixel\n// coverage. Thus, anti-aliasing of intersecting shapes may look wrong. 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.t1); glVertex2f(q.x0,q.y0);\n glTexCoord2f(q.s1,q.t1); glVertex2f(q.x1,q.y0);\n glTexCoord2f(q.s1,q.t0); glVertex2f(q.x1,q.y1);\n glTexCoord2f(q.s0,q.t0); 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.

basic_json::is_boolean(),\n@ref basic_json::is_number() (with @ref basic_json::is_number_integer(),\n@ref basic_json::is_number_unsigned(), and @ref basic_json::is_number_float()),\n@ref basic_json::is_discarded(), @ref basic_json::is_primitive(), and\n@ref basic_json::is_structured() rely on it.\n\n@note There are three enumeration entries (number_integer, number_unsigned, and\nnumber_float), because the library distinguishes these three types for numbers:\n@ref basic_json::number_unsigned_t is used for unsigned integers,\n@ref basic_json::number_integer_t is used for signed integers, and\n@ref basic_json::number_float_t is used for floating-point numbers or to\napproximate integers which do not fit in the limits of their respective type.\n\n@sa @ref

CBOR (Concise\n Binary Object Representation) serialization format.\n\n The library maps CBOR types to JSON value types as follows:\n\n CBOR type | JSON value type | first byte\n

the sense that not all CBOR\n types can be converted to a JSON value. The following CBOR types\n are not supported and will yield parse errors (parse_error.112):\n - date/time (0xC0..0xC1)\n - bignum (0xC2..0xC3)\n - decimal fraction (0xC4)\n - bigfloat (0xC5)\n - expected conversions (0xD5..0xD7)\n - simple values (0xE0..0xF3, 0xF8)\n - undefined (0xF7)\n\n @warning CBOR allows map keys of any type, whereas JSON only allows\n strings as keys in object values.

- Try using `nullptr` instead of `NULL` or call `get()` instead of using the overloaded operator()\n// * Lazy importer can't find the function I want:\n// - Double check that the module in which it's located in is actually loaded\n// - Try #define LAZY_IMPORTER_CASE_INSENSITIVE\n// This will start using case insensitive comparison globally\n// - Try #define
