CATEVENTDISPATCHER

Name


      CatEventDispatcher

Purpose



      The purpose of this utility routine is to intercept the event
      callbacks from widgets and pass the "event" on to an object
      EventHandler method. The EventHandler method must be written
      with one positional parameter: the event structure that comes
      from the widget. Note that the "name" of the object is added
      as a field in every event structure.
