# 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.
