The listener interface for receiving keyboard focus events on
 a component.
 The class that is interested in processing a focus event
 either implements this interface (and all the methods it
 contains) or extends the abstract 
FocusAdapter class
 (overriding only the methods of interest).
 The listener object created from that class is then registered with a
 component using the component's addFocusListener
 method. When the component gains or loses the keyboard focus,
 the relevant method in the listener object
 is invoked, and the FocusEvent is passed to it.- Since:
