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 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 JavaBeansTM
has been added to the java.beans
package. Please see XMLEncoder
.

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 windowClosing
method of a registered WindowListener
object.
HIDE_ON_CLOSE

):
Automatically hide the dialog after

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".

Provides a hint as to whether or not newly created JDialog
s
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 JDialog
s will have their
Window decorations provided by the current LookAndFeel
.
Otherwise, newly created JDialog
s 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);
Params: - defaultLookAndFeelDecorated – A hint as to whether or not current
look and feel should provide window decorations
