<DT>public class <B>ViewportLayout</B><DT>extends java.lang.Object<DT>implements java.awt.LayoutManager, java.io.Serializable</DL>

<P>
The default layout manager for JViewport.  JViewportLayout defines
 a policy for layout that should be useful for most applications.
 The viewport makes its view the same size as the viewport,
 however it will not make the view smaller than its minimum size.
 As the viewport grows the view is kept bottom justified until
 the entire view is visible, subsequently the view is kept top
 justified.
 <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.
