              java.awt.Dialog
                  javax.swing.JDialog

All Implemented Interfaces:

Accessible, ImageObserver, MenuContainer, RootPaneContainer, Serializable, WindowConstants

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. From the older java.awt.Window object you would normally do something like this:

       dialog.add(child);
 

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.

See Also:

setContentPane(java.awt.Container), RootPaneContainer.getContentPane()

setContentPane

public void setContentPane(Container contentPane)

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

Since:

1.4

See Also:

LookAndFeel.getSupportsWindowDecorations()

isDefaultLookAndFeelDecorated

public static boolean isDefaultLookAndFeelDecorated()

Returns true if newly created JDialogs should have their Window decorations provided by the current look and feel. This is only a hint, as certain look and feels may not support this feature.

Returns:

true if look and feel should provide Window decorations.

Since:

1.4

paramString

protected String paramString()

Returns a string representation of this JDialog. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null.

Overrides:

paramString in class Dialog

Returns:

a string representation of this JDialog.

getAccessibleContext

public AccessibleContext getAccessibleContext()

Gets the AccessibleContext associated with this JDialog. For JDialogs, the AccessibleContext takes the form of an AccessibleJDialog. A new AccessibleJDialog instance is created if necessary.

Specified by:

getAccessibleContext in interface Accessible

Overrides:

getAccessibleContext in class Dialog

Returns:

an AccessibleJDialog that serves as the AccessibleContext of this JDialog
