A low-level event that indicates that a window has changed its status. This low-level event is generated by a Window object when it is opened, closed, activated, deactivated, iconified, or deiconified, or when focus is transfered into or out of the Window.
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.
An unspecified behavior will be caused if the id parameter
of any particular WindowEvent instance is not
in the range from WINDOW_FIRST to WINDOW_LAST.
