Use MessageDialog for alerts, and for simple text-only questions.  It's much
easier, and far more consistent with both your own app and the platform.  For
more complicated dialogs it's whatever you like (but use the Dialog base, not
a plain Window).

I usually put together convenient one-liners for my apps (and in a library
common to others) to keep things consistent and compact.


(cut & paste)

  sub confirm {
      my ($parent, $question, $verb, $default) = @_;
      my $dialog = Gtk2::MessageDialog->new ($parent, [], 'question', 'none',
                                             $question);
      $dialog->add_buttons ("Don't $verb" => 'reject',
                            "$verb" => 'accept');
      $dialog->set_default_response ($default || 'reject');
      my $response = $dialog->run;
      $dialog->destroy;
      return 'accept' eq $response;
  }

...

  $main_window->signal_connect (destroy => sub { Gtk2->main_quit });
  $main_window->signal_connect (delete_event => sub {
      my ($win) = @_;
      # return TRUE to inhibit destruction of the window.
      return ! confirm ($win, "Are you sure you want to quit?", "Quit");
  });
