Class JDialog
- All Implemented Interfaces:
- ImageObserver,- MenuContainer,- Serializable,- Accessible,- RootPaneContainer,- WindowConstants
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.

Method Details- 
dialogInitprotected void dialogInit()Called by the constructors to init theJDialogproperly.
- 
createRootPaneCalled by the constructor methods to create the defaultrootPane.- Returns:
- a new JRootPane
 
- 
processWindowEventHandles window events depending on the state of thedefaultCloseOperationproperty.- Overrides:
- processWindowEventin class- Window
- Parameters:
- e- the window event
- See Also:
 
- 
setDefaultCloseOperation@BeanProperty(preferred=true, enumerationValues={"WindowConstants.DO_NOTHING_ON_CLOSE","WindowConstants.HIDE_ON_CLOSE","WindowConstants.DISPOSE_ON_CLOSE"}, description="The dialog's default close operation.") public void setDefaultCloseOperation(int operation) Sets the operation that will happen by default when the user initiates a "close" on this dialog. You must specify one of the following choices:
 - DO_NOTHING_ON_CLOSE(defined in- WindowConstants): Don't do anything; require the program to handle the operation in the- windowClosingmethod of a registered- WindowListenerobject.
- HIDE_ON_CLOSE(defined in- WindowConstants): Automatically hide the dialog after invoking any registered- WindowListenerobjects.
- DISPOSE_ON_CLOSE(defined in- WindowConstants): Automatically hide and dispose the dialog after invoking any registered- WindowListenerobjects.
 The value is set to HIDE_ON_CLOSEby default. Changes to the value of this property cause the firing of a property change event, with property name "defaultCloseOperation".Note: When the last displayable window within the Java virtual machine (VM) is disposed of, the VM may terminate. See AWT Threading Issues for more information. - Parameters:
