Progress Dialog in Swing

Question

How can I make a modal JDialog without buttons appear for the duration it takes a Runnable instance to complete and have that instance update a progress bar/message on that dialog?

Clearly spaghetti code might work, but I'm looking for a clean design if one exists.

Answer 1

You might want to look into ProgressMonitor. It automatically pops up a dialog with a progress bar if the operation is taking a long time; see How to Use Progress Monitors.
