@JavaBean(defaultProperty="JMenuBar", description="A toplevel window for creating dialog boxes.") 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
