   * when the underlying state change is complete. The signal handler should
   * return <tt>true</tt> to prevent the default handler from running.
   * 
   * Visually, the underlying state is represented by the trough color of
   * the switch, while the Gtk::Switch::property_active() property is represented by the
   * position of the switch.
