Eclipse Rich Ajax Platform
Release 1.2

org.eclipse.swt.widgets
Interface Listener

All Known Implementing Classes:
TypedListener

public interface Listener

Implementers of 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.
