public class MultiLookAndFeel extends LookAndFeel
A multiplexing look and feel that allows more than one UI to be associated with a component at the same time. The primary look and feel is called the default look and feel, and the other look and feels are called auxiliary.
For further information, see Using the Multiplexing Look and Feel.
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 JavaBeansTM has been added to the
java.beans
package. Please seeXMLEncoder
