Re: [triquetrum-dev] Ptolemy implementation for relation reconnecting away from a vertex

Thank you, it's done now in Triquetrum as well.

Vergil works like this:
If the dragging is from port to port, then you should create a new relation.
If the dragging is from port to relation or vice versa, then you
should use the existing relation.

Dear ptolemy hackers,
I'm almost there to implement Ptolemy II's "vertex" relation concept (a.k.a. the black diamond) in Triquetrum's editor.
There's one last remaining issue (as far as I know now) : when reconnecting a link away from a vertex, I still need to figure out how/where to decide whether to assign a new relation to the link or not.
E.g. starting from :
<hijccdcj.png>
there is 1 relation linking Const via the Vertex to the Display actor.
After reconnecting to the Display2 actor, the result in Vergil is a new relation2 :
<icgbdibh.png>
In the current Triquetrum status, the result is still the single, but graphically disconnected, relation that now somehow links Const to both Display actors.
I.e. the reconnect action does not create a new relation2.
Could you point me to where to look in Ptolemy's code to figure out all the possible reconnection cases and how to decide when creating a new relation is required?
thanks!
