public class WindowEvent
extends ComponentEvent
A low-level event which indicates that a window has changed its status. This low-level event is generated by a Window object when it is opened, closed, about to close, activated or deactivated, iconified or deconified.

The event is passed to every WindowListener or WindowAdapter object which registered to receive such events using the window's addWindowListener method. (WindowAdapter objects implement the WindowListener interface.) Each such listener object gets this WindowEvent when the event occurs.
