All Implemented Interfaces:
org.eclipse.gef.common.adapt.IAdaptable.Bound<org.eclipse.gef.mvc.fx.parts.IVisualPart<? extends javafx.scene.Node>>, org.eclipse.gef.mvc.fx.handlers.IHandler, org.eclipse.gef.mvc.fx.handlers.IOnDragHandler
public class BendFirstAnchorageOnArcHandleDragHandler extends org.eclipse.gef.mvc.fx.handlers.AbstractHandler implements org.eclipse.gef.mvc.fx.handlers.IOnDragHandler
The BendFirstAnchorageOnSegmentHandleDragHandlerEx is an IOnDragHandler that can be installed on the handle parts of an Connection, so that the user is able to manipulate that connection by dragging its handles. This policy expects that a handle is created for each anchor point of the connection (start, way, end), as well as for each middle point of a segment. Moreover, this policy expects that the respective handles are of type CircleSegmentHandlePart.
