public class JDialog extends Dialog implements WindowConstants, Accessible, RootPaneContainer
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, the add, remove, and setLayout methods of this class are overridden, so that they delegate calls to the corresponding methods of the ContentPane. For example, you can add a child component to a dialog as follows:
dialog.add(child);And the child will be added to the contentPane. The
contentPane is always non-null. Attempting to set it to null generates an exception. The default contentPane has a BorderLayout manager set on it. Refer to RootPaneContainer for details on adding, removing and setting the LayoutManager of a JDialog. 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™ has been added to the java.beans package. Please see XMLEncoder.

If the system property suppressSwingDropSupport is false (the default) and the current drop target on this component is either null or not a user-set drop target, this method will change the drop target as follows: If newHandler is null it will clear the drop target. If not null it will install a new DropTarget.
Note: When used with JDialog, TransferHandler only provides data import capability, as the data export related methods are currently typed to JComponent.
Please see How to Use Drag and Drop and Data Transfer, a section in The Java Tutorial, for more information.

JDialogs should have their Window decorations (such as borders, widgets to close the window, title...) provided by the current look and feel. If defaultLookAndFeelDecorated is true, the current LookAndFeel supports providing window decorations, and the current window manager supports undecorated windows, then newly created JDialogs will have their Window decorations provided by the current LookAndFeel. Otherwise, newly created JDialogs will have their Window decorations provided by the current window manager. You can get the same effect on a single JDialog by doing the following:
JDialog dialog = new JDialog(); dialog.setUndecorated(true); dialog.getRootPane().setWindowDecorationStyle(JRootPane.PLAIN_DIALOG);
