Does anyone have a quick class to produce a JDialog saying processing or something along that lines, to be displayed and automatically disposed of while a procedure is processing... leave the main JFrame process anyway while the JDialog is being displayed and then be automatically disposed of.

If you want to build it yourself then the SwingWorker class makes it fairly straightforward.

What about the isCancelled()?
Where does that fit in to all of it?

There is a "Cancel" button on the progressMonitor dialog...

if the user presses it, isCancelled() returns true...
