public interface FocusListener extends EventListener
Classes which implement this interface provide methods that deal with the events that are generated as controls gain and lose focus.

After creating an instance of a class that implements this interface it can be added to a control using the addFocusListener method and removed using the removeFocusListener method. When a control gains or loses focus, the appropriate method will be invoked.
