Hi there,

Is it possible to change the routing style (either from Sirius design file or programatically or changing the source code) of edges? Right now we have straight, manhattan and tree, I want the edges to bend and have curvy corners. Are all these possible, please?

Cheers,
Will

Hi William,

You can adjust the smoothness value of the routing style once the edge is created - from the appearance view or programmatically: org.eclipse.gmf.runtime.notation.RoutingStyle.setSmoothness(Smoothness) - but this property cannot be specified from the odesign file

Regards,

Florian

Hi Florian,

Many thanks for your response. Could you be more specific and point me to the point where an edge is created?

Cheers,
Will

Hi William,

Sirius relies on the GMF metamodel. The Edge routing style is held by the GMF model serialized in the aird file. You can modify the Edge routing style by retrieving the RoutingStyle of the Edge and edit the smoothness value. The way Sirius creates the GMF Edge is not intended to be extended. The GMF Edges are instantiated in this method: org.eclipse.sirius.diagram.ui.internal.refresh.diagram.DDiagramCanonicalSynchronizer.createConnections(Collection<SiriusLinkDescriptor>, Map<EObject, View>, Diagram).
I can suggest you two way to modify the smoothness of an Edge at the creation time:
* Provide your own org.eclipse.emf.transaction.ResourceSetListener (since Sirius executes all model changes in transactional commands) and implement the Edge modification in a command that will be returned by org.eclipse.emf.transaction.ResourceSetListener.transactionAboutToCommit(ResourceSetChangeEvent).
* Register a new org.eclipse.sirius.business.api.session.ModelChangeTrigger. You can take a look in the ecoreTools project - org.eclipse.emf.ecoretools.design.service.AutosizeTrigger for instance - to have an example of modelChangeTrigger and the way it is provided.

Regards,

Florian

Hi Florian,

I have been at this for several days and still no progress. I planned to go with ModelChangeTrigger, which can be added to SessionEventBroker. However, I have problems with how to get the SessionEventBroker and how this can be integrated in a plug-in that registers a ModelChangeTrigger when I fire up an Eclipse instance.

Any suggestions are much appreciated.

Cheers,
William

Hi,

Sorry, the problem is solved. My apologies if my last post confused you.

Thank you very much.

Cheers,
