    e879.  
    Retrieving the Color Chooser Panels in a JColorChooser Dialog</h3>

There are three chooser panels in the default <code>JColorChooser</code>
dialog. Although each is implemented by a class in the
<code>javax.swing.colorchooser</code> package, these classes are not public.
This example demonstrates how to identify these panels by class name.


<pre>
    JColorChooser chooser = new JColorChooser();
    
    // Retrieve the swatch chooser
    findPanel(chooser, "javax.swing.colorchooser.DefaultSwatchChooserPanel");
    
    // Retrieve the HSB chooser
    findPanel(chooser, "javax.swing.colorchooser.DefaultHSBChooserPanel");
    
    // Retrieve the RGB chooser
    findPanel(chooser, "javax.swing.colorchooser.DefaultRGBChooserPanel");
    
    // Returns the panel instance with the specified name.
    // Returns null if not found.
    public AbstractColorChooserPanel findPanel(JColorChooser chooser, String name) {
        AbstractColorChooserPanel[] panels = chooser.getChooserPanels();
    
        for (int i=0; i&lt;panels.length; i++) {
            String clsName = panels[i].getClass().getName();
    
            if (clsName.equals(name)) {
                return panels[i];
            }
        }
        return null;
    }
