Hi Alex,
I have some problems with displaying edges. I have difficulties to reproduce things outside my application. But I am trying to add arrows. So when I do: (RTLine new color: Color red) + (RTSimpleArrowHead new color: Color red), the text that follow the + brake my visualization: the arrow is wrongly placed. If I remove the + (RTSimpleArrowHead new color: Color red), it works fine.
When I tried to reproduce it, I created an example that does not work, I do not understand why:
=== b := RTGraphBuilder new. shape := RTShapeBuilder new. shape shape: (RTEllipse new color: Color gray; size: 40).
el := (RTElement on: 1). el + shape. b view add: el.
el2 := (RTElement on: 2). el2 + shape. b view add: el2.
l := RTEdge from: el to: el2. b view add: l.
RTCellLayout on: b view elements. b build. b open ===
