Class BalloonLink

GoJS® Diagramming Components
version 3.0.5
by Northwoods Software®

This is an extension and not part of the main GoJS library. Note that the API for this class may change at any time. If you intend to use an extension in production, you should copy the code to your own source directory. See the Extensions intro page for more information.

Hierarchy

This custom go.Link class customizes its go.Shape to surround the comment node (the from node). If the Shape is filled, it will obscure the comment itself unless the Link is behind the comment node. Thus the default layer for BalloonLinks is "Background".

The "corner" property controls the radius of the curves at the corners of the rectangular area surrounding the comment node, rather than the curve at corners along the route, which is always straight. The default value is 10.

If you want to experiment with this extension, try the Balloon Links sample.

Constructors

Accessors

  • Gets or sets width of the base of the triangle at the center point of the go.Link.fromNode.

    The default value is 15.

Methods

  • Copies properties to a cloned BalloonLink.

    Parameters

    Returns void

  • Produce a Geometry from the Link's route that draws a "balloon" shape around the go.Link.fromNode and has a triangular shape with the base at the fromNode and the top at the toNode.

    Returns Geometry
