- All Implemented Interfaces:
- DragTracker, RequestConstants, Tool
- public class ConnectionDragCreationTool
- extends AbstractConnectionCreationTool
- implements DragTracker
A connection creation tool that implements DragTracker. Using this tool, connections
are created by clicking on the source edit part, dragging the mouse to the target edit
part and releasing the mouse. A NodeEditPart
might return this
drag tracker if the mouse is located over an appropriate anchor.
