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
-
dialogInit
protected void dialogInit()Called by the constructors to init theJDialog
properly. -
createRootPane
Called by the constructor methods to create the defaultrootPane
.- Returns:
- a new
JRootPane
-
processWindowEvent
Handles window events depending on the state of thedefaultCloseOperation
property.- Overrides:
processWindowEvent
in classWindow
- 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 inWindowConstants
): Don't do anything; require the program to handle the operation in thewindowClosing
method of a registeredWindowListener
object.HIDE_ON_CLOSE
(defined inWindowConstants
): Automatically hide the dialog after invoking any registeredWindowListener
objects.DISPOSE_ON_CLOSE
(defined inWindowConstants
): Automatically hide and dispose the dialog after invoking any registeredWindowListener
objects.
The value is set to
HIDE_ON_CLOSE
by 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:
operation
- the operation which should be performed when the user closes the dialog- Throws:
IllegalArgumentException
- if defaultCloseOperation value isn't one of the above valid values- See Also:
-
getDefaultCloseOperation
public int getDefaultCloseOperation()Returns the operation which occurs when the user initiates a "close" on this dialog.- Returns:

setTransferHandler
@BeanProperty(hidden=true, description="Mechanism for transfer of data into the component") public void setTransferHandler(TransferHandler newHandler) Sets thetransferHandler

if the component does not support data transfer operations.If the system property
suppressSwingDropSupport
isfalse
(the default) and the current drop target on this component is eithernull
or not a user-set drop target, this method will change the drop target as follows: IfnewHandler
isnull
it will clear the drop target. If notnull
it will install a newDropTarget
.Note: When used with
JDialog
,TransferHandler
only provides data import capability, as the data export related methods are currently typed toJComponent
.Please see How to Use Drag and Drop and Data Transfer, a section in The Java Tutorial, for more information.
