Meta-diagramming [message #1783132]

Howdiheyho,

Can I use DDiagram as a node target in diagrams? I would like to create diagrams that outline the structure of the diagrams in my 'real' model, so that diagrams are nodes in the 'meta-diagram'. The nodes would just display the name of the targeted diagram for example.

What would be the pro way to do this?
Thanks,
Felix

Hi Felix,

> Can I use DDiagram as a node target in diagrams?

The first answer would be yes since the Sirius meta-model is not different from others but in that case, the semantic resource will be the *.aird resource. So I think you will meet some problems with that.
I don't have similar use case in mind. If it does not work, a solution could be to maintain an additional model with references toward the real DReprenstationDescriptor.

Regards,

Florian

Maybe I could use the "Note" tool, annotating the notes that represent diagram references and then format/style these annotated notes differently. I have no clue if that would work, I know too little about GMF

Florian, I am reading through a lot of sirius/gmf/gef code and I found something that could maybe help: Looking at org.eclipse.sirius.diagram.ui.internal.edit.policies.OpenDiagramEditPolicy.OpenDiagramCommand, I can see that Sirius somewhere uses the HintedDiagramLinkStyle in the open diagram command. So I wonder if there is already some support for my usecase. What I haven't found out yet is how I can trigger that command, and how to create a node that actually HAS such a HintedDiagramLinkStyle. I will try to look at sirius test suite and examples, maybe I can find something there?

Hi Felix,

Sorry for the late answer,
We considered the possibility to use the GMF note to make possible to navigate toward representations but we did not go further. The only way today to navigate toward other representations is defining navigation tool in the *.odesign.
The navigation menu use org.eclipse.sirius.ui.tools.internal.editor.MenuHelper.buildOpenRepresentationActions(IMenuManager, IInterpreter, RepresentationNavigationDescription, DRepresentationElement, Session, AdapterFactory) to create the open representation action.
org.eclipse.sirius.diagram.ui.internal.edit.policies.OpenDiagramEditPolicy looks like an old GMF generated code.
