[wxhaskell-users] closing frames and dialogs

[Wolfgang J. <4f4...@ac...>]

Hello,

I want some code to be executed everytime a certain frame or dialog is clos=
ed,=20
either programmatically via close or by the user using the method of the=20
respective windowing system (like pressing Alt+F4).  How do I achieve this?

In addition, I=E2=80=99d like to know what happens with the wxHaskell/wxWid=
gets=20
objects of a frame/dialog (the frame/dialog object and all respective widge=
t=20
objects) when the frame/dialog is closed.  Are they destroyed automatically=
? =20
What happens if they are accessed after the frame/dialog has been closed?

Best wishes,
Wolfgang
