A call to UIManager.get() checks all three levels in order and returns the first non-null value for a key, if any. A call to UIManager.put() just affects the user defaults. Note that a call to setLookAndFeel() doesn't affect the user defaults, it just replaces the middle defaults "level". <p> <strong>Warning:</strong> 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. A future release of Swing will provide support for long term persistence.<P><DL><DT><B>See Also: </B><DD><A HREF="../../serialized-form.html#javax.swing.UIManager">Serialized Form</A></DL><HR><P><!--
