Class MouseTrackAdapter

java.lang.Object
org.eclipse.swt.events.MouseTrackAdapter
All Implemented Interfaces:
EventListener, MouseTrackListener
Direct Known Subclasses:
AnnotationBarHoverManager.Closer
public abstract class MouseTrackAdapter extends Object implements MouseTrackListener
This adapter class provides default implementations for the methods described by the MouseTrackListener interface.

Classes that wish to deal with MouseEvents which occur as the mouse pointer passes (or hovers) over controls can extend this class and override only the methods which they are interested in.

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