javax.swing
class JDesktopPane

java.lang.Object extended by java.awt.Component extended by java.awt.Container extended by javax.swing.JComponent extended by javax.swing.JLayeredPane extended by javax.swing.JDesktopPane
All Implemented Interfaces:
MenuContainer, ImageObserver, Serializable, Accessible, TransferHandler.HasGetTransferHandler
Most common way to construct:

JDesktopPane desktop = new JDesktopPane();

Based on 70 examples 

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). Note that JDesktopPane does not support borders.

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 further documentation and examples see How to Use Internal Frames, a section in The Java Tutorial.

Warning: Swing is not thread safe. For more information see Swing's Threading Policy.

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 {@link java.beans.XMLEncoder}.

Parameters:
dragMode - the style of drag to use for items in the Desktop

setSelectedFrame

public void setSelectedFrame(JInternalFrame f)
Sets the currently active JInternalFrame in this JDesktopPane. This method is used to bridge the package gap between JDesktopPane and the platform implementation code and should not be called directly. To visually select the frame the client must call JInternalFrame.setSelected(true) to activate the frame.

Parameters:
f - the internal frame that's currently selected

setUI

public void setUI(DesktopPaneUI ui)
Sets the L&F object that renders this component.

Parameters:
ui - the DesktopPaneUI L&F object
