public abstract class WindowAdapter extends Object implements WindowListener, WindowStateListener, WindowFocusListener
Extend this class to create a WindowEvent listener
and override the methods for the events of interest. (If you implement the
WindowListener interface, you have to define all of
the methods in it. This abstract class defines null methods for them
all, so you can only have to define methods for events you care about.)
Create a listener object using the extended class and then register it 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.
