public static interface FieldEvents.FocusNotifier
The interface for adding and removing FocusEvent
listeners.
By implementing this interface a class explicitly announces that it will
generate a FocusEvent
when it receives keyboard focus.
Note: The general Java convention is not to explicitly declare that a
class generates events, but to directly define the
addListener
and removeListener
methods. That
way the caller of these methods has no real way of finding out if the
class really will send the events, or if it just defines the methods to
be able to implement an interface.
