I would like to hook some cleanup code into the window destruction 
activities such that when a wxPanel-derived class is destroyed 
(from whatever cause) the cleanup code is executed. I've tried 
overriding the Destroy() function but that doesn't seem to be 
executed when the parent widget is destroyed. 

Any help with this would be greatly appreciated. If I can't do this,
then 
the cleanup code must be done explicitly by any and all clients of 
my panel and in my environment that is sub-optimal. Thanks!
