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.

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.
