 Unless I'm missing something, this would require adding a field to each
wxEvtHandler (and hence each wxWindow) indicating whether it should be
deleted with the window it is associated with. I don't think it's a good
trade-off.

 The solution I use when I need to push-and-forget an event handler is to
catch window destruction event in this handler and do "delete this" from
it. I think it would be nice to have a base class implementing this in a
reusable manner so that you could get this functionality by just deriving
from this wxAutoDeletedEventHandler class.
