This sample demonstrates the use of Activate Events. These are¶

generated when a frame becomes active or inactive. This is typically¶

indicated by a frame's titlebar changing colour, and a widget within¶

the frame gainin focus. An event is also generated when a whole wxRuby¶

app starts or stops being the current focussed desktop application.¶
