Here are some guidelines that you should follow when making your contributions.\n\nStart by forking this repository, then learn [how to run Vis Projects from source code](https://github.com/kotcrab/vis-ui/wiki/Building-Vis-From-Source).\n\n#### Git commits messages\n* Use sentence case (i.e. \"Add feature\" not \"add feature\")\n* Use imperative, present tense (i.e. \"Add\", not \"Added\" or \"Adds\")\n* Don't use dots, exclamation or question marks at the end of commit message\n\n#### Code Formatter\nWe require you to use code formatter when making pull requests. Code formatter for IntelliJ IDEA can be found in root directory of this repository. If you are using Eclipse then\nyou must use [libGDX Eclipse formatter](https://github.com/kotcrab/libgdx/blob/master/eclipse-formatter.xml). \n\nRemember to don't use Eclipse formatter on existing source code because it isn't fully compatible with the IntelliJ IDEA formatter used in this repository. It may change other irrelevant source code and if you decide to make pull request later it will be harder to review.\n\nTo install formatter in Eclipse simply import xml file from settings window.\n\nTo install formatter in IntelliJ IDEA copy xml to config directory, restart IDE, then select formatter from settings. \nMac OS X: `~/Library/Preferences/.IdeaIC15/codestyles/` \nLinux: `~/.IdeaIC15/config/codestyles/` \nWindows: `\\.IdeaIC15\\config\\codeStyles\\`\n\n`.IdeaIC15` directory may be named different depending on your IDEA version\n\n#### Code Style\nPlease follow [libGDX code style](https://github.com/libgdx/libgdx/blob/master/CONTRIBUTING.md#code-style).\n\nThanks!\n" }, { "path": "CONTRIBUTORS", "content": "# This is the official list of people who can contribute\n# (and who have contributed) code to the Vis Project\n# repository.\n# The AUTHORS file lists the copyright holders; this file\n# lists people.\n#\nkotcrab https://github.com/kotcrab\nJavier https://github.com/jdiazcano\nMJ https://github.com/czyzby/\nStrongJoshua https://github.com/StrongJoshua\ncode-disaster https://github.com/code-disaster\npiotr-j https://github.com/piotr-j\nintrigus https://github.com/intrigus\nStQuote https://github.com/StQuote\nFavorlock https://github.com/Favorlock\nstrubelz https://github.com/strubelz\nSnehks https://github.com/Snehks\nericnondahl https://github.com/ericnondahl\nmetaphore https://github.com/metaphore\ncypherdare https://github.com/cypherdare\nfgnm https://github.com/fgnm\nccmb2r https://github.com/ccmb2r\nbploeckelman https://github.com/bploeckelman\n" }, { "path": "LICENSE", "content": "\n Apache License\n Version 2.0, January 2004\n http://www.apache.org/licenses/\n\n TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION\n\n 1.

Alternatively JAR can be downloaded from [Maven repository](http://search.maven.org/#search|gav|1|g%3A%22com.kotcrab.vis%22%20AND%20a%3A%22vis-ui%22). If you are creating new project, you can use gdx-setup to automatically add VisUI for you. (press 'Show Third Party Extension' button)\n\n#### Manual Gradle setup:\n\nOpen build.gradle in project root.\nIn ``ext`` section under ``allprojects`` add:\n```groovy\nvisuiVersion = '1.X.X'\n```\nLook at [CHANGES](https://github.com/kotcrab/vis-ui/blob/master/ui/CHANGES.md) file to see what version of VisUI you can use\nfor your version of libGDX. Note that using not matching versions is likely to cause runtime exceptions.\n\n**Core dependency**\n```groovy\napi \"com.kotcrab.vis:vis-ui:$visuiVersion\"\n```\n\n**HTML dependency** (only if you are using GWT):\n```groovy\napi \"com.kotcrab.vis:vis-ui:$visuiVersion:sources\"\n```\n\n``GdxDefinition.gwt.xml`` and ``GdxDefinitionSuperdev.gwt.xml``:\n```xml\n\n```\n\nRefresh Gradle dependencies.\n\n## Usage\n\nUsing VisUI is pretty simple, to load or unload the skin call:\n```java\nVisUI.load();\nVisUI.dispose();\n```\n\nCreate your UI like always, for extra skin features you have to use Vis widgets instead of standard scene2d.ui:\n\n| VisUI | Standard scene2d.ui |\n| ------------- | ------------------- |\n| VisLabel | Label |\n| [LinkLabel](https://github.com/kotcrab/vis-ui/wiki/LinkLabel) | - |\n| VisCheckBox | CheckBox |\n| VisList | List |\n| VisProgressBar| ProgressBar |\n| VisRadioButton| - |\n| VisScrollPane | ScrollPane |\n| VisSelectBox | SelectBox |\n| VisSlider | Slider |\n| VisSplitPane | SplitPane |\n| VisTextArea | TextArea |\n| VisTextButton | TextButton |\n| VisImageTextButton | ImageTextButton |\n| VisImageButton | ImageButton |\n| VisTextField | TextField |\n| [VisValidatableTextField](https://github.com/kotcrab/vis-ui/wiki/VisValidatableTextField) | - |\n| VisTree | Tree |\n| VisWindow | Window |\n| VisTable | Table |\n| [DragPane](https://github.com/kotcrab/vis-ui/wiki/DragPane) | - |\n| [GridGroup](https://github.com/kotcrab/vis-ui/wiki/GridGroup) | - |\n| [ListView](https://github.com/kotcrab/vis-ui/wiki/ListView) | - |\n| [TabbedPane](https://github.com/kotcrab/vis-ui/wiki/TabbedPane) | - |\n| [Spinner](https://github.com/kotcrab/vis-ui/wiki/Spinner) | - |\n| [CollapsibleWidget](https://github.com/kotcrab/vis-ui/wiki/CollapsibleWidget) | - |\n| [ButtonBar](https://github.com/kotcrab/vis-ui/wiki/ButtonBar) | - |\n| [FlowGroups](https://github.com/kotcrab/vis-ui/wiki/FlowGroups) | - |\n\nUsing Vis widgets is necessary for proper focus border management. All VisUI widgets constructors do not have Skin argument, they are using VisUI.skin field.\n\n### VisTable\n\nVisTable allows to easily set default spacing for vis components, construct it like this:\n```\nVisTable table = new VisTable(true);\n```\n\nVisTable also allows adding vertical and horizontal separators to table:\n```java\ntable.addSeparator() //horizontal\ntable.addSeparator(true) //vertical\n```\n\n### Using different `SkinScale`s\n\nDefault VisUI skin can be too small for high resolution screens or mobile devices, in that case you can load a upscaled skin version simply by calling:\n```\nVisUI.load(SkinScale.X2);\n```\n\n### Internal classes\n\nClasses inside `com.kotcrab.vis.[...].internal` packages are considered private and aren't part of public API. Changes to that classes won't be listed in change log.\n\n### Default title align\n\nDefault title align for VisWindow and VisDialog is `Align.left` this can be changed by calling:\n```java\nVisUI.setDefaultTitleAlign(int align)\n```\nCalling this method does not affect windows that have been already created.\n\n## Modifying skin\n\n[Raw skin files](https://github.com/kotcrab/vis-ui/tree/master/ui/assets-raw) are available if you would like to modify them. After you pack them using libGDX texture packer, add generated atlas to your project with [uiskin.json, default.fnt and font-small.fnt](https://github.com/kotcrab/vis-ui/tree/master/ui/src/main/resources/com/kotcrab/vis/ui/skin/x1) and load it by calling:\n```java\nVisUI.load(Gdx.files.internal(\"path/to/your/modified/files/uiskin.json\"))\n```\nConsider using USL if you want to extend existing VisUI styles.

\n * Can be embedded in a scroll pane.

\n *
\n * Key differences:\n *

    \n *
  • Can be configured to have a layout direction as either horizontal ({@code vertical=false}) or vertical ({@code vertical=true}).
    • \n *
  • Layout direction can be changed programmatically during runtime.
    • \n *
  • If available, uses up all necessary space in the layout direction, i.e., when {@code vertical=false}, attempts to expand horizontally and, when {@code vertical=true}, attempts to expand vertically (instead of using the specified width/height as before).
    • \n *
  • Adds spacing only between children, but not after the last element.
    • \n *
  • When even the first child does not fit its row/column, space is no longer placed before it.
    • \n *
