All Implemented Interfaces:
java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible

public class JColorWheel
extends javax.swing.JPanel

The JColorWheel displays a hue/saturation wheel of the HSB color model. The user can click at the wheel to pick a color on the JColorWheel. The JColorWheel should be used together with a HSB brightness color slider.
