              a look and feel for a UI object and the look and feel does not
              support that UI. This message can be annoying, especially to auxiliary
              look-and-feel developers who don't want to support a particular
              component.</p>
            <p>Fortunately, you can prevent this error
              message by creating a subclass of the <code>UIDefaults</code>
              class and returning an instance of it from the
	      <code>getDefaults</code> method
