At first I have to apologize: That sound really arrogant, saying 'try
googling ...'. I was a little fast shouting with this answer.
Didn't mean it that way.
When I started with my extra event handlers, some month ago, i first
thought of calling 'delete this' the way you described. Wondering if
this is legal I started googling and found many answers.
Yes thats totally legal, but used the wrong way will lead to serious
problems. Following a discussion at comp.lang.c++.moderated with about
50 entries was too much to read for me so i decided to write this
manager object to be on the sure side.
Agreed, all of this is philosophical and offtopic here.

Programming wx for about 5 years and never read about wxEVT_DESTROY.
If I have heard about this before, all the discussion and many hours
of brain work weren't necessary.
Call me stupid, but where do I find anything about this event in the
manual?
