  27  * Provides user interface objects built according to the Basic look and feel.
  28  * The Basic look and feel provides default behavior used by many look and feel
  29  * packages. 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>

  44  * Most of the Swing API is <em>not</em> thread safe. For details, see
