OpenJDK 27 · javax.swing.JWindow · APIdia, the JavaDoc alternative

A JWindow is a container that can be displayed anywhere on the user's desktop. It does not have the title bar, window-management buttons, or other trimmings associated with a JFrame, but it is still a "first-class citizen" of the user's desktop, and can exist anywhere on it.

The JWindow component contains a JRootPane as its only child. The contentPane should be the parent of any children of the JWindow. 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 window as follows:

      window.add(child);

And the child will be added to the contentPane. The contentPane will always be non-null. Attempting to set it to null will cause the JWindow to throw an exception. The default contentPane will have a BorderLayout manager set on it. Refer to javax.swing.RootPaneContainer for details on adding, removing and setting the LayoutManager of a JWindow.

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 JWindow on a different screen device. See java.awt.Window 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 java.beans.XMLEncoder.

If not `null` it will install a new `DropTarget`. Note When used with `JWindow`, `TransferHandler` only provides data import capability, as the data export related methods are currently typed to `JComponent`.
