       subclass based on the type of the Lire::Config::Value $value. The onvaluechanged is an

   value()
       Returns the Lire::Config::Value object which is edited by this view.

   onValueChanded( $code )
       Changes the event handler connected to the 'onvaluechanged' event.  This event is trigger
       whenever the Lire::Config::Value associated to this widget is modified.

   refresh_view()
       This method can be called to update the view to reflect modifications to the underlying
       Lire::COnfig::Value.
