Hi,

I need to retrieve the EMF resource from the diagram currently being edited. I got an earlier tip to do this via calling resolveSemanticElement on one of the edit parts generated by GMF and then call eResource on the returned EObject:

final Resource resource = yourEditPart.resolveSemanticElement().eResource;

But I'm quite new to GMF (as in, I have only used its high level functions, and have never got this deep into directly working with java code), and I don't quite know how to do this (as in, how do I get the desired editpart).

The code will be invoked from a wizard created using Epsilon Wizard Language.

Any tips on how to do this would be appreciated (using the presented approach or any other way to do it), but please specify full source code.

Cheers,
Endre

Hi Andre,

an easy way to retrieve the editingdomain from the currently active
diagram (be sure, it is active) could be as follows:

IWorkbenchPage page =
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage();
(IDiagramWorkbenchPart) diagramPart = (IDiagramWorkbenchPart)
page.getActiveEditor();
IDiagramEditDomain domain = diagramPart.getDiagramEditDomain();

From the IDiagramWorkbenchPart you can also retrieve the
DiagramEditPart and its contained children.

Make sure to add proper instanceof and null checks, if you cannot assure
he correctness of the cast to the IDiagramWorkbenchPart.

HTH,
Thomas

Hi Thomas,

Thanks for the tip, the following:

IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
IDiagramWorkbenchPart diagramPart = (IDiagramWorkbenchPart)page.getActiveEditor();
ModelEditPart editPart = (ModelEditPart) diagramPart.getDiagramEditPart();

did solve my problem.

Cheers,
Endre
