Class JDialog

Implemented Interfaces:
Accessible, ImageObserver, MenuContainer, RootPaneContainer, Serializable, WindowConstants
Known Direct Subclasses:
PrinterDialog
public class JDialog
extends Dialog
implements Accessible, WindowConstants, RootPaneContainer
A dialog window. This is an extension of Dialog that provides support for the Swing architecture. Most importantly it contains a JRootPane as it's only top-level child, that manages the content pane, the menu and a glass pane. Also, unlike java.awt.Dialogs, JDialogs support the Swing Pluggable Look & Feel architecture.
