Nope, should be able to access widgets after quitting. What do you mean
"failed"? Can you post the exact error message, and/or a small compilable
program demonstrating the problem?

This is the correct way to do it, gtk_main() is recursive for that reason
(but be careful not to let the user invoke the wrong gtk_main_quit(), such
as the Exit menu item for your application...)

If they aren't in www.gtk.org/rdp or the GTK tutorial or my book
(developer.gnome.org/doc/GGAD) then they are probably undocumented, but I
would expect them to be in one or more of those places.
