public class ViewportLayout extends Object implements LayoutManager, Serializable
JViewport
. ViewportLayout
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. 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 has been added to the java.beans
package. Please see XMLEncoder
