changing the color of JProgressBar

[Aryeh M. Friedman]

I have a JProgressBar that I want to be green if the underlaying
process has no errors and red if it does. I can't seem to find a way
of setting the color of the bar in the raw JProgressBar class... ideas?

Try JProgressBar.setForeground(Color c)

Try JProgressBar.setForeground(Color c)

No effect

I think you'll find the colour is controlled by the prevailing PLAF.
