Interface MouseWheelHelper

All Known Implementing Classes:
ViewportMouseWheelHelper
public interface MouseWheelHelper
MouseWheelHelpers provide each EditPart to handle mouse-wheel events in their own desired way. By default, when mouse-wheel events are generated that have no stateMask, a default MouseWheelHandler delegates the task to the MouseWheelHelper that is returned by the getAdapter() method of the EditPart in focus.

The most common usage of MouseWheelHelpers involves scrolling of an EditPart's figure. They should be returned in the EditPart's getAdapter() method.
