I didn't understand exactly. Do you mean that you *don't* handle the
delete event and still keep a pointer to the widget? And then the widget
is hidden for you and you can re-show it later?

If that's the case, well -- you got what you asked for: undefined
behaviour ;-)

If you don't handle the delete event, the widget gets marked for
destroy. Later it gets the destroy event (at this point the widget is no
longer quite functional: think of it as a last cleanup thing). Then it
goes away. Nobody guarantees you that all those things happen
immediately.

But then maybe I didn't understand your post correctly.
