What works is to connect the signal to

        gint foo (GtkObject *object)
        {
           gtk_signal_emit_stop_by_name (object, "button_press_event");
           return FALSE;
        }

but this looks quite ugly.
 
You can also also do this:

        gtk_signal_connect_after (GTK_OBJECT (entry), "button_press_event",
                                  GTK_SIGNAL_FUNC (gtk_false), NULL);

to let the event be handled by the entry *and* go to the window.

BTW, I looked into gtkentry.c and found that gtk_entry_button_press
always returns FALSE, which in my program causes the (grand)-parent
widget to be focussed when I click on the entry. I tried

        gtk_signal_connect_after (GTK_OBJECT (entry), "button_press_event",
                                  GTK_SIGNAL_FUNC (gtk_true), NULL);

and it works. I'm using a quite outdated version of Gtk+ (1.2.1), is
this a bug, or intended, or already fixed, or what else ...?
