For some reason, when I opened a JDialog inside an ActionListener (called
from a menu item), thecomponents inside the dialog didn't get painted until
ActionListener existed. I had JProgressBar inside, that's why it was
important to have it displayed. I overrode the paint function and see
if it ever get call. None.
Any fixes to this problem?
Thanks,

It seems to me, that you want to access the JProgressBar from the code outside
of the AWT event thread, if that is the case, you may have to use SwingWorker,
SwingUtililies.invokeLater(), or Open JDialog from a non_AWT Event thread.

Thanks. I guess that I will try both SwingWorker and invokeLater ()
and see which one is easier.
