14  * A class which tags a window with a particular semantic usage,
15  * either tooltip, menu, sub-menu, popup-menu, or comobobox-popup.
16  * This is used as a temporary solution for getting native AWT support
17  * for transition effects in Windows 98 and Windows 2000. The native
18  * code will interpret the windowType property and automatically
19  * implement appropriate animation when the window is shown/hidden.
20  * <p>
21  * Note that support for transition effects may be supported with a
22  * different mechanism in the future and so this class is
23  * package-private and targeted for Swing implementation use only.
24  * <p>
25  * <strong>Warning:</strong>
26  * Serialized objects of this class will not be compatible with
27  * future Swing releases. The current serialization support is appropriate
28  * for short term storage or RMI between applications running the same
29  * version of Swing. A future release of Swing will provide support for
30  * long term persistence.
