protected void play()
{
     getTimeSet().setCurrentMjdIndex(getTimeSet().getCurrentMjdIndex() + 1);
     timeSettings.fireCurrentMjdChange();
     timeSettings.Render();
}try 
{
    forward = new JButton(new ImageIcon(Utils.findResource("images/VCRForward.gif")));
}
catch (java.io.FileNotFoundException e2) 
{ 
   e2.printStackTrace(System.err);
   forward = new JButton();
}
forward.setName("forward");
forward.addActionListener( new ActionListener() {
     public void actionPerformed(ActionEvent evt) {
         play();
}
});
autorun = new Jbutton()
autorun.addActionListener( new ActionListener() {
     public void actionPerformed(ActionEvent evt) {
            timer = new Timer(true);
            TimerTask tt = new TimerTask()
            {
                  public void run()
                  {
                        play();
                  }
            };
            timer.schedule(tt, 0, 3 * 1000);
}
});
这样行不行？

protected TimerThread timerThread=null;autorun.addActionListener( new ActionListener() {
     public void actionPerformed(ActionEvent evt) {
            if(timerThread!=null)
                  return;
            timer = new Timer(true);
            TimerTask tt = new TimerTask()
            {
                  public void run()
                  {
                      timerThread = new TimerThread();
                      timerThread.run();
                  }
            };
            timer.schedule(tt, 0, 3 * 1000);
}
});
stopButton = new Button("stop");
stopButton.addActionListener( new ActionListener() {
     public void actionPerformed(ActionEvent evt) {
            if(timerThread == null)
                  return;
            timerThread.stop();
}
});class TimerThread implements Runnable
{
      Timer timer;
      public TimerThread()
      {
      }
      public void run()
      {
            timer = new Timer(true);
            TimerTask tt = new TimerTask()
            {
                  public void run()
                  {
                        play();
                  }
            };
            timer.schedule(tt, 0, 3 * 1000);
      }
      public void stop()
      {
            timer.cancel();
      }
}

没有刷新视图是指没刷新组件吗？有没有调用repaint()方法，你看看这个吧，我用得好好的呀，：）
