public class FXBendOnSegmentHandleDragPolicy
extends AbstractFXOnDragPolicy

The FXBendOnSegmentHandleDragPolicy is an AbstractFXOnDragPolicy 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 FXCircleSegmentHandlePart.

This callback method is invoked when the mouse is moved while a button is pressed.

Specified by:

drag in class AbstractFXOnDragPolicy

Parameters:

e - The original MouseEvent.

delta - The mouse offset since AbstractFXOnDragPolicy.press(MouseEvent) (in pixel).

getBendPolicy

protected FXBendPolicy getBendPolicy(IVisualPart<javafx.scene.Node,? extends javafx.scene.Node> targetPart)

Returns the FXBendPolicy that is installed on the given IVisualPart.

Parameters:

targetPart - The IVisualPart of which the installed FXBendPolicy is returned.

Returns:

The FXBendPolicy that is installed on the given IVisualPart.

getHost

public FXCircleSegmentHandlePart getHost()

Description copied from interface: IPolicy

Returns the host of this IPolicy, i.e. the IVisualPart this IPolicy is attached to.
