JDesktopPane (Java 2 Platform SE 5.0) (original) (raw)

javax.swing

Class JDesktopPane

java.lang.Object extended by java.awt.Component java.awt.Container javax.swing.JComponent javax.swing.JLayeredPane javax.swing.JDesktopPane

All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable, Accessible

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 extendsJLayeredPane to manage the potentially overlapping internal frames. It also maintains a reference to an instance ofDesktopManager that is set by the UI class for the current look and feel (L&F). Note that JDesktopPane does not support borders.

This class is normally used as the parent of JInternalFrames to provide a pluggable DesktopManager object to theJInternalFrames. The installUI of the L&F specific implementation is responsible for setting thedesktopManager 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 further documentation and examples seeHow to Use Internal Frames, a section in The Java Tutorial.

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 JavaBeansTM has been added to the java.beans package. Please see XMLEncoder.
