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 conveniance add and its variants, remove and setLayout have been overridden to forward to the contentPane as necessary. This means you can write:
From the older java.awt.Window object you would normally do something like this:
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.
Using JDialog the proper semantic is:
dialog.getContentPane().add(child);
The same principle holds true for setting layout managers, removing components, listing children, etc. All these methods should normally be sent to the contentPane instead of to the JDialog. 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.
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.
For the keyboard keys used by this component in the standard Look and Feel (L&F) renditions, see the
JDialog key assignments
.
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
.

By default, children may not be added directly to this component, they must be added to its contentPane instead. For example:
thisComponent.getContentPane().add(child)
An attempt to add to directly to this component will cause an runtime exception to be thrown if rootPaneCheckingEnabled is true. Subclasses can disable this behavior.

setLayout
public void setLayout(LayoutManager manager)
-
Sets the LayoutManager. Overridden to conditionally forward the call to the contentPane. Refer to
RootPaneContainer
for more information.
By default the layout of this component may not be set, the layout of its contentPane should be set instead. For example:
thisComponent.getContentPane().setLayout(new GridLayout(1, 2))
An attempt to set the layout of this component will cause an runtime exception to be thrown if rootPaneCheckingEnabled is true. Subclasses can disable this behavior.

Parameters:

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
