JColorChooser ignores setEnabled() function call

Name: vi73552 Date: 03/22/99


Create a JColorChooser object and place it on a panel.
Apply the setEnabled(boolean) function on this object.
On setEnabled(false), the object should be grayed out,
and no more color selection possible. setEnabled(true) should
invert this.
In fact, JColorChooser objects ignore the setEnabled(false) call.
Selection of a color is always allowed.

Sample Code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
