Class BalloonLink

This is an extension and not part of the main GoJS library. Note that the API for this class may change at any time. Extensions can be found in the GoJS kit under the extensions or extensionsTS folders. See the Extensions intro page for more information.

Hierarchy

This custom Link class customizes its 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".

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