GoLabeledLink snap to grid

I have been able to snap my extended GoTextNode’s to a 20x20 grid. The links between the nodes should also snap to the grid. The links need to have a label so I have used GoLabeledLink but I cant override CalculateStroke. Any hints?
Best regards

GoLabeledLink has a RealLink… which is the “real GoLink”. Override CreateRealLink in your GoLabeledLink class. See Flowgrammer’s ChartLink for a sample.
