public class TestBar
extends javax.swing.JPanel

This class is used to form the test bars that TestPattern uses. TestBar displays a gradient from one end of the bar to another.

You might find it interesting that instances of this class are fully-functional containers, meaning that you can place other components on top of the gradient background. This can be handy for building that gradient background setup program you've always wanted...

API Stability: Alpha.
