	 * Warning: Serialized objects of this class will not be
	 * compatible with future Swing releases. The current serialization support
	 * is appropriate for short term storage or RMI between applications running
	 * the same version of Swing. As of 1.4, support for long term storage of
	 * all JavaBeans^TM has been added to
	 * the java.beans package. Please see
