e880. Retrieving the Color Chooser Panels in a JColorChooser DialogThere are three chooser panels in the defaultJColorChooser
dialog. Although each is implemented by a class in the
javax.swing.colorchooser package, these classes are not public.
This example demonstrates how to identify these panels by class name.
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<panels.length; i++) { String clsName = panels[i].getClass().getName(); if (clsName.equals(name)) { return panels[i]; } } return null; }
