Class ExpandAdapter

java.lang.Object

org.eclipse.swt.events.ExpandAdapter

All Implemented Interfaces:

EventListener, ExpandListener, SWTEventListener

public abstract class ExpandAdapter
extends Object
implements ExpandListener

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

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

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