Direct Known Subclasses:

JHarmonicColorWheel

public class JColorWheel
extends javax.swing.JPanel

The JColorWheel displays a wheel made of two components of a ColorSpace.

The user can click at the wheel to pick a color.

The JColorWheel should be used together with a color slider for the remaining color component(s) of the color system.
