Diagram Coordinates [message #1702473]

Hi!

I would like to know how can I get the coordinates for each diagram element. I suppose they are stored in the representation file (.aird), but I was wondering what is the best approach to retrieve and process this information. Of course, by doing this I still want to be able to associate the coordinates with the semantic element from the model.

Kind regards

Hello,

You have the helper
org.eclipse.sirius.diagram.ui.internal.refresh.GMFHelper that provides
services you are looking for. Note that this is used with GMF diagram
element. If in your context you have Sirius diagram elements, you will
need to use
org.eclipse.sirius.diagram.ui.business.api.view.SiriusGMFHelper.getGMFNode(DDiagramElement)
first.

Regards,
Steve

Hello,

Thank you for the quick response.

I went for the Sirius Javadoc, but having some problems in generating it properly and still have to get used to it.
Meanwhile, as far as I can see, in order to retrieve the DDiagramElements in the first place, I imagine I should somehow load the .aird file, get the DView, then the DRepresentation (as DDiagram) and then invoke getOwnedDiagramElements, right?

Cheers

Hello,

That really depends on the context of the process that need to get the
coordinates. For exemple, if it is a java service that is called at the
execution of a Sirius tool, you already have the DDiagramElement as a
variable. Can you describe what you are doing that requires having
diagram elements coordinates?

Regards,
Steve

Hi.

Thank you for your help.

Well, I would like to translate my model into another modeling language. Lets say I want to compile it to another graphical language describing the same system. I know I have the semantic information in one place and the graphical one in the .aird.
What do you think would be the easiest way to translate my model but still carrying around these coordinates?

I am still new to this world so thank you for your patience.

Kind regards.
