Question

I have a start and stop button. I was told that I must use a SwingWorker. The code that I have now works fine. I start it and I stop it. But what if i want to start it again..? I am reading that the doinBackground method will only be executed once. Is there a way to fire it off again..??

Right now I cannot create a new instance of that Swing Worker because in my Swing Worker I have a while loop that says while(isSet) which is set to True when I click on the Start Button and set to False when I click on the stop button.

Is there a way around this..??

Thanks

The SwingWorker API doc answers your question:

SwingWorker is only designed to be
executed once. Executing a SwingWorker
more than once will not result in
invoking the doInBackground method
twice.

You’ll need to create a new SwingWorker instance each time your start button is pressed.
