Widget drawing is done by the Style helper object, declared in libgag/include/GUIStyle.h. It has a default implementation in libgag/src/GUIStyle.cpp. Glob2 reimplements it partially in src/Glob2Style.h/.cpp to have things like bitmapped buttons, etc... |

All widget share some color constants. They are defined in the GAGGUI::ColorTheme namespace and initialized in the beginning of the libgag/src/GUIBase.cpp file. |

Button can have associated bitmaps. To do so, when you create the button, pass the name of a valid loaded sprite and two valid frame numbers, the first for idle and the second for highlighted state. If you pass no sprite name ("") and -1 to frame numbers, bitmap are disabled and default color theme is used. |

GUI theming is made at two levels in glob2: widget theming and background theming
Widget theming
Widget drawing is done by the Style helper object, declared in libgag/include/GUIStyle.h. It has a default implementation in libgag/src/GUIStyle.cpp. Glob2 reimplements it partially in src/Glob2Style.h/.cpp to have things like bitmapped buttons, etc...
Background theming
Each GUI screen inherits from the Glob2Screen class, defined in src/Glob2Screen.h and implemented in src/Glob2Screen.cpp. This class reimplement the Screen::paint virtual method so that a custom paint method is implemented.
