You need to connect a handler that returns TRUE to delete_event; (TRUE
== I handled it) gtk_widget_hide_on_delete() is a "precanned" handler
that may be useful for this purpose.

Mentioned in:

 http://developer.gnome.org/doc/GGAD/cha-gtk.html

I can't think of where it woudl be in the GTK+ docs, if anywhere.
