public interface Listener
Listener
provide a simple
handleEvent()
method that is used internally by SWT to
dispatch events.
After creating an instance of a class that implements this interface it can
be added to a widget using the
addListener(int eventType, Listener handler)
method and
removed using the
removeListener (int eventType, Listener handler)
method. When
the specified event occurs, handleEvent(...)
will be sent to
the instance.
Classes which implement this interface are described within SWT as providing
the untyped listener API. Typically, widgets will also provide a
higher-level typed listener API, that is based on the standard
java.util.EventListener
pattern.
