Examples of diva.canvas.interactor.DragInteractor

diva.canvas.interactor.DragInteractor
An interactor that responds to mouse drag events. It adds the notion of constraints, so that dragging can be limited to certain coordinates or "snapped" to suitable locations, and a "target" array, which contain the figure or figures that are dragged. @version $Id: DragInteractor.java,v 1.14 2005/12/14 04:12:39 cxh Exp $ @author John Reekie
