WindowsPopupWindow

      - javax.swing.JWindow

public class WindowsPopupWindow extends JWindow

A class which tags a window with a particular semantic usage, either tooltip, menu, sub-menu, popup-menu, or comobobox-popup. This is used as a temporary solution for getting native AWT support for transition effects in Windows 98 and Windows 2000. The native code will interpret the windowType property and automatically implement appropriate animation when the window is shown/hidden.

Note that support for transition effects may be supported with a different mechanism in the future and so this class is package-private and targeted for Swing implementation use only.

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. A future release of Swing will provide support for long term persistence.
