Cancelling an actionListener...?

[greenonions79]

Hello all,

I'm kind of new to Java and having problem using actionListeners...

In the application I'm develping when a user clicks on the startButton, it fires an actionListener which which displays a countdown on screen and updates it every second. My problem is that if the user clicks on the startButton for a second time it fires another actionlistener - so that there are two countdowns displayed on screen. I would prefer it if the first countdown could be cancelled and only the new one displayed. Is there a way to do this?

This is an extract from my code

if (source == game.startButton){
     Date startTime = new Date();
     ActionListener timeListen = new TimeLogic(startTime);
     Timer stopWatch = new Timer(1000, timeListen);

Thanks a lot

if (source == game.startButton){
   if not Active then {  // Active is a boolean declared
                         // at the class level
      Active = true;
      Date startTime = new Date();
      ActionListener timeListen = new TimeLogic(startTime);
      Timer stopWatch = new Timer(1000, timeListen);
   } else {
      // 1) Stop the current countdown here
      // 2) restart the countdown
      // I suggest putting the code which is identical
      // for both branches of the if statement in a 
      // separate procedure.
   }

So in short every time the startButton is pressed you check to see if a count down is running, if it is cancel it and start again. Easy. ----------------------------------------
