Provides user interface objects that combine two or more look and feels.

  Provides user interface objects that combine two or more look and feels. When a component asks for its UI, this look and feel returns a multiplexing UI that handles all communications with both the default look and feel and one or more auxiliary look and feels. For example, if a user combines an auxiliary audio look and feel with the Motif look and feel, the JButton.getUI method would return an instance of MultiButtonUI, which would handle both a MotifButtonUI and an AudioButtonUI.

For more information, see Using the Multiplexing Look and Feel.

Note: Most of the Swing API is not thread safe. For details, see Threads and Swing, a section in The Java Tutorial.
