All Implemented Interfaces:

public class JDialog
extends Dialog
implements WindowConstants, Accessible, RootPaneContainer

The main class for creating a dialog window. You can use this class to create a custom dialog, or invoke the many class methods in JOptionPane to create a variety of standard dialogs. For information about creating dialogs, see The Java Tutorial section How to Make Dialogs.

The JDialog component contains a JRootPane as its only child. The contentPane should be the parent of any children of the JDialog. As a convenience add and its variants, remove and setLayout have been overridden to forward to the contentPane as necessary. This means you can write:

       dialog.add(child);
 

Please see the JRootPane documentation for a complete description of the contentPane, glassPane, and layeredPane components.

In a multi-screen environment, you can create a JDialog on a different screen device than its owner. See Frame for more information.

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 JavaBeans^TM has been added to the java.beans package. Please see XMLEncoder.
