All Implemented Interfaces:: PropertySupport

public class WindowProperty extends Object implements PropertySupport

A sessionState property for Window.

This class defines how the session state for Windows is saved and and restored in terms of a property called sessionState. The Window's bounds Rectangle is saved and restored if the dimensions of the Window's screen have not changed.

WindowProperty is registered for Window.class by default, so this class applies to the AWT Window, Dialog, and Frame class, as well as their Swing counterparts: JWindow, JDialog, and JFrame.
