public class JScrollPane

extends JComponent

implements ScrollPaneConstants, Accessible

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 Swing1.0 applications. It will not be possible to load serialized Swing1.0 objects with future releases of Swing. The JDK1.2 release of Swing will be the compatibility baseline for the serialized form of Swing objects.

 public Border getViewportBorder()

Returns:

the value of the viewportBorder property.

See Also:

setViewportBorder

 public void setViewportBorder(Border viewportBorder)

Add a border around the viewport. Note that the border isn't set on the viewport directly, JViewport doesn't support the JComponent border property. Similarly setting the JScrollPanes viewport doesn't effect the viewportBorder property.

The default value of this property is computed by the look and feel implementation.

This is a JavaBeans bound property.

getViewportBorder, setViewport

 public JScrollBar createHorizontalScrollBar()
