Hi Ricardo,
thanks for the hints and offer of help. My mockup could would be this:
| view elements e1 e2 |
view := RTView new.
elements := ((RTEllipse new size: 30; color: Color white))
elementsOn: #(one two).
view addAll: elements.
elements @ RTDraggable.
RTCircleLayout new initialRadius: 70; on: elements.
e1 := RTEdge from: elements first to: elements second.
e1 + (RTLine new color: Color black) + (RTArrow new color: Color black) @ (RTLabelled new
text: '12'; view: view).
view add: e1.
e2 := RTEdge from: elements second to: elements first.
e2 + (RTLine new color: Color black) + (RTArrow new color: Color black) @ (RTLabelled new
text: '21'; view: view).
view add: e2.
view open

Hi Johan,
For your first question, you could change the attachPoint of the Lines, which will
automatically change the arrow to appear on the border.
As for the "arched lines", there is a class called RTDirectedLine which does
just that.
If you could provide a mockup code on what are you trying to do, I could help you
further.
Regards,
Ricardo

Hi all,
I have the following situation: a node named ‘one’ and a node named ‘two’, I want to draw
an arrow ‘onetwo' from one to two, and ‘twoone' from two to one. Nodes are
ellipses with size 30, and a label. Arrows are an edge + line + arrow + label construct.
So I get the image like below, which raises two2 questions.
<arrows.tiff>
First question: how can I make the arrows go to the border of the ellipse, instead of the
center?
Second question: as a human I would draw each of the two arrows with a curve: one curving
up and one curving down so that they (and their labels) do not overlap. Can I do something
like this in Roassal? Because now readability is far from optimal.
