Yes, I use it. It's easier than aiming at a little hot-spot.
Stuart Parmenter ask for a ctree mode without any hot-spots. This mode can't
work without the double-click functionality. But it should be easy for you
to stop this event if you don't want it. Simply do something like :


   ctree = gtk_ctree_new_with_titles (2, 0, title);
   gtk_signal_connect (GTK_OBJECT (ctree), "button_press_event",
                       GTK_SIGNAL_FUNC (button_press), NULL);

gint button_press (GtkCTree *ctree, GdkEventButton *event, gpointer data)


  if (event->button == 1 && event->type == GDK_2BUTTON_PRESS)   
     gtk_signal_emit_stop_by_name (GTK_OBJECT (ctree), "button_press_event");

I don't want to make it configurable, because in this case we have to make
all button events configurable. That would only make sense if we had something
like key-bindings for mouse buttons too.
