[vtkusers] Java AddObserver and Events!

[Jeff Lee]

  private DelayAction _delayAction = new DelayAction();
  private Timer timer = new Timer(10, _delayAction);
  iren.AddObserver("CreateTimerEvent", this, "StartTimer");

...
  public void StartTimer() {
    if (timer.isRunning())
      timer.stop();
   
    timer.setRepeats(false);

    timer.start();
  }

  private class DelayAction implements ActionListener {
    public void actionPerformed(ActionEvent evt) {

          Lock();
          iren.TimerEvent();
          UnLock();
    }
  }

This was all done inside of vtkCanvas.  Have a look there.
Regards,
Jeff
