java.awt.dnd.DropTarget

psdi.webclient.applet.wfcanvas.diagram.dnd.WorkflowDropTarget

All Implemented Interfaces:

java.awt.dnd.DropTargetListener, java.io.Serializable, java.util.EventListener

public class WorkflowDropTarget
extends java.awt.dnd.DropTarget

This class implements autoscrolling for the version of the drag and drop that doesn't use the native handlers. The reason is that unlike the native code , the muse event is not reported as the component scrolls under it thus the mouse location has to be updated in the timer code
