browser/external/raygui-4.0/README.md

raygui is a simple and easy-to-use immediate-mode-gui library.

raygui was originally inspired by Unity IMGUI (immediate mode GUI API).

raygui was designed as an auxiliar module for raylib to create simple GUI interfaces using raylib graphic style (simple colors, plain rectangular shapes, wide borders...) but it can be adapted to other engines/frameworks.

raygui is intended for tools development; it has already been used to develop multiple published tools.

WARNING: Latest raygui from master branch is always aligned with latest raylib from master branch. Make sure to use the appropiate versions.

WARNING: Master branch now contains raygui 4.0-dev, it is an API-BREAKING redesign from previous versions (3.x), now all functions are more consistent and coherent, you can read the details about this breaking change in issue 283

NOTE: raygui is a single-file header-only library (despite its internal dependency on raylib), so, functions definition AND implementation reside in the same file raygui.h, when including raygui.h in a module, RAYGUI_IMPLEMENTATION must be previously defined to include the implementation part of raygui.h BUT only in one compilation unit, other modules could also include raygui.h but RAYGUI_IMPLEMENTATION must not be defined again.

features

• Immediate-mode gui, no retained data
• +25 controls provided (basic and advanced)
• Powerful styling system for colors, font and metrics
• Standalone usage mode supported (for other graphic libs)
• Icons support, embedding a complete 1-bit icons pack
• Multiple tools provided for raygui development

raygui controls

basic controls

Label       |  Button      |  LabelButton |  Toggle      |  ToggleGroup  |  ToggleSlider
CheckBox    | ComboBox     |  DropdownBox |  TextBox     |  ValueBox     |  Spinner
Slider      |  SliderBar   |  ProgressBar |  StatusBar   |  DummyRec     |  Grid

container/separator controls

WindowBox   |  GroupBox    |  Line        |  Panel       |  ScrollPanel  | TabBar

advanced controls

ListView    |  ColorPicker |  MessageBox  |  TextInputBox

raygui styles

raygui comes with a default style automatically loaded at runtime:

Some additional styles are also provided for convenience, just check styles directory for details:

Custom styles can also be created very easily using rGuiStyler tool.

Styles can be loaded at runtime using raygui GuiLoadStyle() function. Simple and easy-to-use.

raygui icons

raygui supports custom icons, by default, a predefined set of icons is provided inside raygui as an array of binary data; it contains 256 possible icons defined as 16x16 pixels each; each pixel is codified using 1-bit. The total size of the array is 2048 bytes.

To use any of those icons just prefix the #iconId# number to any text written within raygui controls:

if (GuiButton(rec, "#05#Open Image")) { /* ACTION */ }

It's also possible to use the provided GuiIconText() function to prefix it automatically, using a clearer identifier (defined in raygui.h).

if (GuiButton(rec, GuiIconText(RICON_FILE_OPEN, "Open Image"))) { /* ACTION */ }

Provided set of icons can be reviewed and customized using rGuiIcons tool.

raygui support tools

• rGuiStyler - A simple and easy-to-use raygui styles editor.

  

• rGuiIcons - A simple and easy-to-use raygui icons editor.

  

• rGuiLayout - A simple and easy-to-use raygui layouts editor.

  

building

raygui is intended to be used as a portable single-file header-only library, to be directly integrated into any C/C++ codebase but some users could require a shared/dynamic version of the library, for example, to create bindings:

• Windows (MinGW, GCC)

copy src/raygui.h src/raygui.c
gcc -o src/raygui.dll src/raygui.c -shared -DRAYGUI_IMPLEMENTATION -DBUILD_LIBTYPE_SHARED -static-libgcc -lopengl32 -lgdi32 -lwinmm -Wl,--out-implib,src/librayguidll.a

• Windows (MSVC)

copy src\raylib.h src\raylib.c
cl /O2 /I../raylib/src/ /D_USRDLL /D_WINDLL /DRAYGUI_IMPLEMENTATION /DBUILD_LIBTYPE_SHARED src/raygui.c /LD /Feraygui.dll /link /LIBPATH ../raylib/build/raylib/Release/raylib.lib /subsystem:windows /machine:x64

• Linux (GCC)

mv src/raygui.h src/raygui.c
gcc -o raygui.so src/raygui.c -shared -fpic -DRAYGUI_IMPLEMENTATION -lraylib -lGL -lm -lpthread -ldl -lrt -lX11

• Mac (clang, homebrew installed raylib)

cp src/raygui.h src/raygui.c
brew install raylib
gcc -o raygui.dynlib src/raygui.c -shared -fpic -DRAYGUI_IMPLEMENTATION -framework OpenGL -lm -lpthread -ldl $(pkg-config --libs --cflags raylib)
