public class JDesktopPane
extends JLayeredPane
implements Accessible
A container used to create a multiple-document interface or a virtual desktop. You create JInternalFrame objects and add them to the JDesktopPane. JDesktopPane extends JLayeredPane to manage the potentially overlapping internal frames. It also maintains a reference to an instance of DesktopManager that is set by the UI class for the current Look and Feel (L&F).

This class is normally used as the parent of JInternalFrames to provide a pluggable DesktopManager object to the JInternalFrames. The installUI of the L&F specific implementation is responsible for setting the desktopManager variable appropriately. When the parent of a JInternalFrame is a JDesktopPane, it should delegate most of its behavior to the desktopManager (closing, resizing, etc).

For the keyboard keys used by this component in the standard Look and Feel (L&F) renditions, see the JDesktopPane key assignments.

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.
