Maybe it's a problem with my system, which is not quite up-to-date. :(

If I add this function,

  gint delete_event_impl(GdkEventAny *){ 
    g_print( "delete event occured\n"); 
    Gtk_Main::instance()->quit(); ;
    return 0;
  }

than, when I close the window via wm, I get these:

delete event occured

** WARNING **: file gtkobject.c: line 1140 (gtk_object_get_data_by_id):
"GTK_IS_OBJECT (object)"

** WARNING **: gtk_signal_disconnect(): could not find handler (1)

If I return 1 or return nothing, then everything's OK. Why ? I'm also
surprised that the g++ doesn't complain when you return nothing, though
the function require an gint to be returned.

OBS: if I don't whant to let the window be deleted at all, then I return
1 and not call Gtk_Main::instance()->quit().

TIA,
