Changing the Color Chooser Panels : JColorChooser « Swing « Java Tutorial

  1. Create your own by subclassing the AbstractColorChooserPanel class.
  2. To add a new panel to the existing set, call: public void addChooserPanel(AbstractColorChooserPanel panel)
  3. To remove it: public AbstractColorChooserPanel removeChooserPanel(AbstractColorChooserPanel panel)
  4. To replace the existing set of panels: setChooserPanels(AbstractColorChooserPanel panels[ ])
public abstract class AbstractColorChooserPanel extends JPanel {
  public AbstractColorChooserPanel();
  protected abstract void buildChooser();
  protected Color getColorFromModel();
  public ColorSelectionModel getColorSelectionModel();
  public int getDisplayMnemonicIndex();
  public abstract String getDisplayName();
  public abstract Icon getLargeDisplayIcon();
  public int getMnemonic();
  public abstract Icon getSmallDisplayIcon();
  public void installChooserPanel(JColorChooser);
  public void paint(Graphics);
  public void uninstallChooserPanel(JColorChooser);
  public abstract void updateChooser();
