Remarks

A GoLink is a GoStroke that connects two GoPorts. Make a link by constructing a link, setting both the F:Northwoods.GoWeb.GoStrokeStyle.Bezier%, it takes the GoStroke.Curviness into account to automatically give the link a curve.

When the link is Orthogonal, it is common to set the style to RoundedLine. Then the GoStroke.Curviness property controls the size of the corners in the link.

Whenever either port is moved (normally because the port's parent node moved), CalculateStroke is called again. By default this will calculate all of the stroke points again. However, if you set the AdjustingStyle property, CalculateStroke will take the old path into account in calculating the new path.

Example

Typical programmatic usage might be something like:

GoBasicNode node1 = new GoBasicNode();
node1.LabelSpot = GoObject.Middle;
node1.Text = "basic node 1";
node1.Shape.BrushColor = Color.LightGreen;
node1.Location = new PointF(75, 50);
goView1.Document.Add(node1);
            
GoBasicNode node2 = new GoBasicNode();
node2.LabelSpot = GoObject.Middle;
node2.Text = "basic node 2";
node2.Shape.BrushColor = Color.LightYellow;
node2.Location = new PointF(200, 50);
goView1.Document.Add(node2);
            
GoLink link = new GoLink();
link.ToArrow = true;
link.FromPort = node1.Port;
link.ToPort = node2.Port;
goView1.Document.Add(link);
