actualy, if you connect it like this:

gtk_signal_connect_object(GTK_OBJECT(button),
			  "clicked",
			  GTK_SIGNAL_FUNC(gtk_widget_destroy),
			  GTK_OBJECT(window));
gtk_signal_connect(GTK_OBJECT(window),
		   "destroy",
		   GTK_SIGNAL_FUNC(gtk_main_quit),
		   NULL);

the application exits also if you destroy the window through the
window manager, because this just breaks the main loop in main().
so main should look something like this:


int
main    (int    argc,
         char   *argv[])
{
	... some initialization stuff
	
	/* gtk's main loop
	*/
	gtk_main();
	
	
        /* exit program (optional call to gtk_exit() )
        */
        /* gtk_exit(0); */
        
        
        /* exit point if gtk_exit() has not been called,
         * suppress compiler warnings otherwise
        */
        return 0;
}
