Set borders in a "Rectangle" shape

Hi,

Is possible set only some borders (border-top, border-bottom, border-right or border-left) in a “Rectangle” shape? like css

Regards,

I’m afraid we don’t offer that, but you could use two concentric Rectangle shapes, one with a different margin than the other, since you can put a different margin on each side.

What kind of shape are you trying to make, exactly?

Or you could just define your own named figure(s) for the borders that you want:

  go.Shape.defineFigureGenerator("TopLeftCorner", function(shape, w, h) {
    return new go.Geometry()
        .add(new go.PathFigure(0, h, false)
             .add(new go.PathSegment(go.PathSegment.Line, 0, 0))
             .add(new go.PathSegment(go.PathSegment.Line, w, 0)));
  });

For an example use, here’s a modified node template taken from samples/minimal.html:

    // define a simple Node template
    myDiagram.nodeTemplate =
      $(go.Node, "Auto",  // the Shape will go around the TextBlock
        $(go.Shape, "TopLeftCorner",
          { strokeWidth: 2 },
          // Shape.stroke is bound to Node.data.color
          new go.Binding("stroke", "color")),
        $(go.TextBlock,
          { margin: 3 },  // some room around the text
          // TextBlock.text is bound to Node.data.key
          new go.Binding("text", "key"))
      );

Which produces:

that is great :sunglasses:

thank u!

still don’t understand how w,h works ?
how to draw rectangle form it ?

The figure generator needs to return a Geometry that has a size given by the width and height arguments. https://gojs.net/latest/api/symbols/Geometry.html

The Shape determines the stroke and fill as well as the size that is passed to the figure generator.
