Class FXBendPolicy

java.lang.Object

org.eclipse.gef4.mvc.policies.AbstractPolicy<javafx.scene.Node>

org.eclipse.gef4.mvc.fx.policies.FXBendPolicy

All Implemented Interfaces:

IAdaptable.Bound<IVisualPart<javafx.scene.Node,? extends javafx.scene.Node>>, ITransactional, IPolicy<javafx.scene.Node>

public class FXBendPolicy
extends AbstractPolicy<javafx.scene.Node>
implements ITransactional

The FXBendPolicy can be used to manipulate the points constituting an FXConnection, i.e. its start point, way points, and end point. When moving a point the policy takes care of:

• Removing overlaid neighbor points.
• Re-adding temporarily removed neighbor points.
• Reconnecting points to the IVisualPart under mouse when applicable.
