Class BoundedDragInteractor
java.lang.Object
diva.canvas.interactor.AbstractInteractor
diva.canvas.interactor.DragInteractor
diva.canvas.interactor.BoundedDragInteractor
- All Implemented Interfaces:
- LayerListener, LayerMotionListener, Interactor, EventListener
public class BoundedDragInteractor
- extends DragInteractor
An interactor that drags its target only within a given
rectangular region. An instance of this class sets itself up so
that the dragged figures or items always remain within the given
region. To do so, it creates an instance of BoundsConstraint that
it attaches to itself, and overrides the setup() method to
initialize the constraint according to the size of the target.
This interactor is intended more as an example of how to
produce a customized drag-interactor than anything else.
