Hi everyone,

1. Is there a possibillty to customize the appearance of edges, so that they are automatically smooth?

I know in the diagram view, I can set the Smoothness of edges to None, Normal, Less or More. Can I change the default value from None to Normal in my odesign File?

2. Is there a way to disable the workability of an edge? I don't want, that someone can move the bend-points.


3. If I want to have 2 edges for a bidirectional connection, do I have to define 2 edges in my odesign File and how can I bind these edges together so when I click on one of them that both edges are selected, like in this picture:
index.php/fa/25011/0/
This is also the edge I asked in my second question.

Regards,
Frank

This appearance parameter cannot be customized using in the odesign
file. A possible solution would be adding your own
org.eclipse.sirius.business.api.session.ModelChangeTrigger in the
org.eclipse.sirius.business.api.session.SessionEventBroker. If a new GMF
edge is created, the ModelChangeTrigger will be notified and that let
the opportunity to change its appearance. The SessionEventBroker can be
retrieved from the Sirius session
(org.eclipse.sirius.business.api.session.Session). You will find various
examples in the Sirius source code. The sessionEvenBroker is registered
as a pre-commit listener, that means the ModelChangeTrigger will be
notified in pre-commit of the EMF transaction.

There is nothing in Sirius to do this easily. It's possible deactivate
the corresponding editPart
(org.eclipse.sirius.diagram.ui.edit.api.part.AbstractDiagramEdgeEditPart.deactivate()).
The edge will remain visible but the end-user will not be able to modify
it at all (that also means the edge appearance).

That will also ask to provide your own mechanism, probably a custom
edgeEditPart etc.
