Ok, we will have a look at this.

Hi All,
Yes indeed, I am very interested in this. Well, I already hacked together a way to
display lines of opposite directions, but if this concept could be generalized and
integrated into Roassal (by someone with better knowledge of Roassal then me :)), that
would be very cool.
What I did is I created the class QSLine which has a offset property. This property
simple offsets the line from its attachment point.
In my layout builder (QSVisualizer), I go through all edges and bundle them together as
"bundled edges" by looking at all sources and destinations.
If such a bundle has more than one edge (meaning it has two edges going in opposite
directions to the same two nodes), I offset the lines of these edges in opposite
directions. This has to be done outside of QSLine, since the lines don't and
shouldn't know if they have a "twin".
All of the code can be found in the Quicksilver-UI Package.
Quicksilver can be loaded in the following way:
Gofer new
smalltalkhubUser: 'Quicksilver' project: 'Quicksilver';
package: 'ConfigurationOfQuicksilver';
load.
ConfigurationOfQuicksilver loadDefault.
The code where I bundle the edges together and offset them, can be found in:
QSVisualizer:edgesFor: nodes view: view
QSLine can also be found in the Quicksilver-UI Package. It is a subclass of ROLine.
Cheers,
Dennis

Yes, I think it would be better to display
2->2 lines.
Currently we cannot render 2->2 lines, but it would not be complicated to add a
particular line shape for this.
How do you mean "special shape"? Would it work in this example?:
---
view shape rectangle size: 20.
view nodes: #(1 2 3 4 5).
view shape line color: Color green.
view edgesToAll: #(1 2 3 4 5).
view circleLayout.
---
So every node will have 4 green edges to other node and 1 green edge to itself.
I think we should also consider that in that example we cannot see two lines: one 1->2
and other 2->1. Should we take care of it and instead of two direct lines use, for
example, bezier lines with different configuration?
I agree that ideally we should be able to see two lines 1->2 and 2->1. Currently we
cannot because we do not have the appropriate shapes for this.
I think user should see it.
Yes. There is several way to do this. As Softwarenaut does, is to have an offset.
By the way, scg guys, you never asked for such a thing? Now is a good moment for shouting
:-)

But we could imagine a special shape that draw such edges.

https://www.iam.unibe.ch/mailman/listinfo/moose-dev All other methods in Roassal do not create
2->2 edges. This was only one. I think there is no visualisation support for such
edges.

Hi,
Not really. When we say edgesToAll: we mean to draw edges from all nodes to all computed
nodes. So, 2->2 is part of it, too. For a different behavior we should introduce
another utility method.
Cheers,
Doru

Your right Juraj, we should not have the edge 2->2.
Would you mind to write a couple of tests and fix this problem please?
Cheers,
Alexandre
