Class ControlAdapter

java.lang.Object

org.eclipse.swt.events.ControlAdapter

All Implemented Interfaces:

EventListener, ControlListener, SWTEventListener

public abstract class ControlAdapter
extends Object
implements ControlListener

This adapter class provides default implementations for the methods described by the ControlListener interface.

Classes that wish to deal with ControlEvents can extend this class and override only the methods which they are interested in.

An alternative to this class are the static helper methods ControlListener.controlMovedAdapter(java.util.function.Consumer) and ControlListener.controlResizedAdapter(java.util.function.Consumer), which accept a lambda expression or a method reference that implements the event consumer.
