Class OrthogonalLinkReshapingTool Extension

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. Extensions can be found in the GoJS kit under the extensions (for loading via script tags),extensionsTS (UMD modules), or extensionsJSM (ES6 modules) folders. See the Extensions intro page for more information.


The OrthogonalLinkReshapingTool class lets a user drag a tool handle along the link segment, which will move the whole segment.

If you want to experiment with this extension, try the Orthogonal Link Reshaping sample.
