( |
|
) |
[inline, virtual] |
Shut down the application. All non-gadget objects should be deleted in an override of this function, and all hardware should be shut down, etc. This base method will shut down the SDL system, so it must be called as the last function if overridden in an SDL application.

) |
[inline, virtual] |
Initialise the application. All initial GUI creation, hardware setup, etc, should be done in an override of this method. The base method should be called as the first instruction in the overridden function. This method must call enableDrawing() and draw() at some point or nothing will be visible.
virtual bool WoopsiUI::Woopsi::swapGadgetDepth |
