The technique for using a Swing timer is discussed in the Java Tutorial in
the Swing chapter. A complete example, ProgressBarDemo.java, is provided and
discussed in this topic. Links to discussions and examples of
general-purpose timers also appear on that same page.

  /**
   * Start periodic timer to unhighlight cells.

  void startTimer()
     {
     final ActionListener refresher = new ActionListener()
        {
        public void actionPerformed( ActionEvent evt )
           {
          ...
              }
           }
        };
     periodic =  new Timer( Config.FADE_UPDATE_FREQUENCY, refresher
);
