public class JDialog
- extends Dialog
- implements WindowConstants, Accessible, RootPaneContainer
The main class for creating a dialog window. You can use this class to create a custom dialog, or invoke the many class methods in
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
conveniance
add and its variants, remove and setLayout have been overridden to forward to the contentPane as necessary. This means you can write:
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
TM
has been added to the java.beans package. Please see
XMLEncoder

HIDE_ON_CLOSE (defined in WindowConstants): Automatically hide the dialog after invoking any registered WindowListener objects.
-
DISPOSE_ON_CLOSE (defined in WindowConstants): Automatically hide and dispose the dialog after invoking any registered WindowListener 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

setTransferHandler
public void setTransferHandler(TransferHandler newHandler)
-
Sets the transferHandler property, which is a mechanism to support transfer of data into this component. Use null if the component does not support data transfer operations.
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.

setDefaultLookAndFeelDecorated
public static void setDefaultLookAndFeelDecorated(boolean defaultLookAndFeelDecorated)
-
Provides a hint as to whether or not newly created 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);
-
-
-
Parameters:
-
defaultLookAndFeelDecorated - A hint as to whether or not current look and feel should provide window decorations
