It contains components, layout managers, events, event listeners, 30 * and adapters. You can subclass the classes in this package to create your own 31 * customized look and feel. 32 * <p> 33 * These classes are designed to be used while the corresponding 34 * {@code LookAndFeel} class has been installed 35 * (<code>UIManager.setLookAndFeel(new <i>XXX</i>LookAndFeel())</code>). 36 * Using them while a different {@code LookAndFeel} is installed may produce 37 * unexpected results, including exceptions. Additionally, changing the 38 * {@code LookAndFeel} maintained by the {@code UIManager} without updating the 39 * corresponding {@code ComponentUI} of any {@code JComponent}s may also produce 40 * unexpected results, such as the wrong colors showing up, and is generally not 41 * encouraged. 42 * <p> 43 * <strong>Note:</strong> 44 * Most of the Swing API is <em>not</em> thread safe.
