Find ConnectionEditPart for corresponding EObject [message #488672]

Dear GMF folks,

I have an EObject that is the model element of the view of an
ConnectionEditPart. How can I determine the EditPart for that EObject in
an active GMF editor?

For any other EditParts than connections this seems pretty simple:

DiagramEditor editor = ...
DiagramEditPart dep = editor.getDiagramEditPart();
EditPart editPart = dep.findEditPart(dep, eObject);

However, for connections this returns null, because a connection edit
part is not contained in any other edit part in the diagram. Although a
connection EP has a parent, this parent does not have this connection EP
as a child. Is this really desired behavior?? Seems a bit odd to me.

Any other way to search for a connection edit part? How could I obtain
all connection edit parts and iterate them manually?

Cheers,
Hauke

Hello Hauke,

See org.eclipse.gef.editparts.AbstractEditPart.registerModel() - any EditPart's
model will be registered there, so you can use:
getViewer().getEditPartRegistry().get(<view>) to access EditPart representing
link view.
