BoundedDragInteractor

java.lang.Object
- diva.canvas.interactor.AbstractInteractor
- - diva.canvas.interactor.DragInteractor
  - - diva.canvas.interactor.BoundedDragInteractor

All Implemented Interfaces:

LayerListener, LayerMotionListener, Interactor, java.util.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.
