Re: Quick Time Java -CallBacks



this is some old code i found on this mailing list which might do what you want.........
hope it helps......

public void setupCallBacks(Movie mov){
   TaskAllMovies.addMovieAndStart();
   TimeBase tbase = mov.getTimeBase();
   Timer timer = new Timer (1, 2, new MovieTickler(), mov);
   TimeBaseExtremesCallBack callb = new
     TimeBaseExtremesCallBack(tbase, StdQTConstants.triggerAtStop,
timer);
   callb.callMeWhen();
   timer.setActive(true);
}


class TimeBaseExtremesCallBack extends ExtremesCallBack {

   private Timer timer;

public TimeBaseExtremesCallBack(TimeBase b, int flag, Timer t)
throws 
QTException {
     super(b, flag);
     timer = t;
   }

   /** Called when movie ends. */
   public void execute() {
     TaskAllMovies.removeMovie();
     cancelAndCleanup();
     timer.setActive(false);
     ....
     <perform some AWT/Swing code>
     ....
   }
}
