Class MouseTrackAdapter
java.lang.Object
org.eclipse.swt.events.MouseTrackAdapter
- All Implemented Interfaces:
EventListener
,MouseTrackListener
,SWTEventListener
- Direct Known Subclasses:
AnnotationBarHoverManager.Closer
This adapter class provides default implementations for the
methods described by the
MouseTrackListener
interface.
Classes that wish to deal with MouseEvent
s 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.
