Getting Mapped Model [message #89935]

I am trying to write my own "tool" with GMF that affects elements in my
EMF model. I have created a Generic Tool, and set the class to a
subclass of a GEF tool. Now this works well, and I get the proper GEF
requests, etc...

Now when I button is pressed I need to get the EMF model element mapped
to that editpart. The edit part is correct, but getModel() returns a
NodeImpl (an GMF class) not the EMF model element I have mapped to this
edit part. Is there a way to get the EMF model element that was mapped
to a particular edit part? There must be a way since GMF is doing it
all over the place.

cheers,
ian

Hi Ian,
maybe this is what you are looking for?
/**
* Gets the semantic element associated to this editpart's view.
* @return the semantic element or <code>null</code> if the semantic
element was
* <code>null</code> or unresolvable
*/
public EObject resolveSemanticElement();

its from the IGraphicalEditPart Interface in
oeg.runtime.diagram.ui.editparts

cheers,

Thanks so much!

I also found getElement on the node model.

((View)getTargetEditPart().getModel()).getElement())

Not sure what the difference is. The one you found seems to do a few
more checks.

Cheers,
Ian
