jdk.awt.event.WindowEvent
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.

*-window-activatedclj
Static Constant.
The window-activated event type. This event is delivered when the Window becomes the active Window. Only a Frame or a Dialog can be the active Window. The native windowing system may denote the active Window or its children with special decorations, such as a highlighted title bar. The active Window is always either the focused Window, or the first Frame or Dialog that is an owner of the focused Window.

*-window-closingclj
Static Constant.
The "window is closing" event. This event is delivered when the user attempts to close the window from the window's system menu. If the program does not explicitly hide or dispose the window while processing this event, the window close operation will be cancelled.

null - java.awt.Window
