How to add a progress bar?

Question

I have been trying to understand how to add a progress bar, I can create one within the GUI I am implementing and get it to appear but even after checking through http://doc

Answer 1

See my answer on another SO question which includes an example of a JProgressBar which gets updated by using a SwingWorker. The SwingWorker is used to execute a long running task in the background (in case of the example it is just a regular Thread.sleep) and report on progress at certain intervals.

I would also strongly suggest to take a look at the Swing concurrency tutorial for more background info on why you should use a SwingWorker when performing long-running tasks which interfere with the UI.

A similar example as the one I posted is available in the Swing tutorial about JProgressBars, which it also worth looking at
