Which is the right one to use for Swing components? I have always used
JPanels with a method paint(Graphics g) and then just called that
method using 'repaint()'. But after reading some of the discussions
here I found out that the correct way to go is to use
paintComponent(Graphics g). Why is this? What is the difference
between the two methods? Thanks for any advice.

Yes, you should use paintComponent. calling super.paintComponent and
using setOpaque replaces the old update/paint mechanism.
You can trace the calls or look at the code in source.zip, but when I
did that, I could not understand what the new scheme bought them.
I just use it.
