Last change on this file since 12168 was 11809, checked in by landauf, 7 years ago

added work around for a bug in cegui 0.8 (the cegui lua scripts expect a "Font*" pointer to call getTextExtent(), but cegui 0.8 only returns "const Font*")

82    @class GUIManager
83    @brief
84        Provides a simple interface to CEGUI with tolua methods and console commands. It also acts as a key and mouse handler.
85
86        The GUIManager is a singleton and can be called anywhere when access on the GUI is needed.
87
88        Since the GUI needs user input, the GUIManager implements the functions needed to act as a key and/or mouse handler.
89        Those input events are then injected into CEGUI in Lua.
