43 * <code>JColorChooser</code> provides a pane of controls designed to allow
44 * a user to manipulate and select a color.
45 * For information about using color choosers, see
46 * <a
47 href="http://java.sun.com/docs/books/tutorial/uiswing/components/colorchooser.html">How to Use Color Choosers</a>,
48 * a section in <em>The Java Tutorial</em>.
49 *
50 * <p>
51 *
52 * This class provides three levels of API:
53 * <ol>
54 * <li>A static convenience method which shows a modal color-chooser
55 * dialog and returns the color selected by the user.
56 * <li>A static convenience method for creating a color-chooser dialog
57 * where <code>ActionListeners</code> can be specified to be invoked when
58 * the user presses one of the dialog buttons.
59 * <li>The ability to create instances of <code>JColorChooser</code> panes
60 * directly (within any container). <code>PropertyChange</code> listeners
61 * can be added to detect when the current "color" property changes.
62 * </ol>
63 * <p>
64 * <strong>Warning:</strong> Swing is not thread safe. For more
65 * information see <a
66 * href="package-summary.html#threading">Swing's Threading
67 * Policy</a>.
68 * <p>
69 * <strong>Warning:</strong>
70 * Serialized objects of this class will not be compatible with
71 * future Swing releases. The current serialization support is
72 * appropriate for short term storage or RMI between applications running
73 * the same version of Swing. As of 1.4, support for long term storage
74 * of all JavaBeans<sup><font size="-2">TM</font></sup>
75 * has been added to the <code>java.beans</code> package.
76 * Please see {@link java.beans.XMLEncoder}.
