    examples: connect gtk_main_quit to "destroy" signal
    
    the default implementation of the delete-event signal
    already calls gtk_widget_destroy and its callbacks should
    return a gboolean differently from gtk_main_quit.
    
    Simpler connect it to GtkWidget "destroy" signal,
    avoiding the risk of a double call to
    gtk_widget_destroy with relative warning.
