Detailed Description

Builds a ConnectionWidget.

Attributes

color: The color of the edge
AttributeStroke (modified for the edge)
sourceShape: AnchorShape for the source side
targetShape: AnchorShape for the target side
pointShape: PointShape for the control points
pointRound: Number used in ConnectionWidget#setControlPointCutDistance(int)
router: Router used by the edge, by default the free router is used
name: The name for the AnchorKey.
from: The ConcreteObject for the AnchorKey of the source.
to: The ConcreteObject for the AnchorKey of the target.

Contents

The contents are evaluated as AnchorDecorator and added as the children of the edge.

Result

A sub-type of ConnectionWidget or an empty component if the required anchors are not present in the scene.
