An event being sent when a top level window is maximized.
Notice that it is not sent when the window is restored to its original size after it had been maximized, only a normal SizeEvent is generated in this case.
Currently this event is only generated in wxMSW, wxGTK, OSX/Cocoa and OS2 ports so portable programs should only rely on receiving wxEVT_SIZE and not necessarily this event when the window is maximized.
Handlers bound for the following event types will receive a MaximizeEvent parameter.
