source: code/branches/resource/src/core/GUIManager.h @ 3348

Last change on this file since 3348 was 3346, checked in by rgrieder, 15 years ago

Moved GraphicsManager and GUIManager to the core. Almost no actual code changes though, just moving (here was that Map-hack I had to move to GSGraphics).

52    @class GUIManager
53    @brief
54        Provides a simple interface to CEGUI with tolua methods and console commands. It also acts as a key and mouse handler.
55
56        The GUIManager is a singleton and can be called anywhere when access on the GUI is needed.
57        Creation of the GUIManager is therefore not possible and the cunstructor is private.
58
59        Since the GUI needs user input, the GUIManager implements the functions needed to act as a key and/or mouse handler.
60        Those input events are then injected into CEGUI in Lua.
