I have seen several examples of a JProgress bar and file transphers, but I need a JProgressBar to show the time it takes to process something.

Does anyone have an example where the a programming is calculating information and the a JProgressBar is being displayed?

Do I need to use a Thread and how would I do it?
Thanks - Ronnie

Are you looking for a progress bar that is really showing the time left or maybe how long something has taken already?

It would be pretty easy to start a timer and have it call a method which updates your display. Timers run on the event dispatch thread, so updating your GUI would be safe.

Does this help?

I have a program that seems to takes a long time to process/calculate information. In stead of having a blank screen I wanted the user to understand that the program is working.

If you can get something like a file size in you heavy–process method you can use the determinate mode in the JProgressBar.
