| 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. |
