public interface FocusListener
- extends org.eclipse.swt.internal.SWTEventListener
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.
