JXButton (SwingLabs JavaDoc)

A Painter enabled subclass of JButton. This class supports setting the foreground and background painters of the button separately. By default, JXButton creates and installs two Painters; one for the foreground, and one for the background. These default Painters delegate to the installed UI delegate.

For example, if you wanted to blur just the text on the button, and let everything else be handled by the UI delegate for your look and feel, then you could:

If either the foreground painter or the background painter is set, then super.paintComponent() is not called. By setting both the foreground and background painters to null, you get exactly the same painting behavior as JButton. By contrast, the Painters installed by default will delegate to the UI delegate, thus achieving the same look as a typical JButton, but at the cost of some additional painting overhead.
