Interface WindowListener
- All Superinterfaces:
EventListener
- All Known Implementing Classes:
AWTEventMulticaster
,BasicToolBarUI.FrameListener
,JMenu.WinListener
,WindowAdapter
The listener interface for receiving window events.
The class that is interested in processing a window event
either implements this interface (and all the methods it
contains) or extends the abstract
WindowAdapter
class
(overriding only the methods of interest).
The listener object created from that class is then registered with a
Window using the window's addWindowListener
method. When the window's status changes by virtue of being opened,
closed, activated or deactivated, iconified or deiconified,
the relevant method in the listener object is invoked, and the
WindowEvent
is passed to it.- Since:
