i would've sworn this was in the gtk+ faq, but it's apparently not.

when then window manager attempts to destroy a window, it sends the 
"delete-event" to the window.

GtkWindow's default handler for delete-event is to destroy the window.  
if you connect your own handler to delete event, you can decide whether 
to let the default handler run.

   $window->signal_connect (delete_event => sub {
       my ($self) = @_;  # also an event, but we don't need it
       # do something interesting, like ask the user if he really
       # wants to exit, etc.
       if ($really_want_to_close) {
           # allow default handler to run, which will destroy
           # the window.
           return FALSE;
       } else {
           # inhibit default handler and keep window alive
           return TRUE;
       }
   });
