Hi Javier,
I have only got a Diagram d. I have not got an EditPart Object. So I
can't use your code template. And for a diagram object I have not found
a way to get to the viewer.
Thanks,
Walter

Hi Walter,
I found a way around this. It works, but I think it's not the best
programming style.
I put some code into the class ....diagram.part.XxxDiagramEditor:
/**
* @generated NOT
*/
private static XxxDiagramEditor instance;
/**
* @generated NOT
*/
public XxxDiagramEditor() {
super(true);
instance = this;
}
/**
* @generated NOT
*/
public static XxxDiagramEditor getInstance() {
return instance;
}
This works, because the constructor is only called once at the opening
of the diagram.
Now I can get the EditPartRegistry from everywhere in the code like this:
DiagramGraphicalViewer dgv = (DiagramGraphicalViewer)
XxxDiagramEditor.getInstance().getDiagramGraphicalViewer();
Map<?, ?> editPartRegistry = dgv.getEditPartRegistry();
If anyone finds a better method, I would appreciate to hear about.
Best wishes
Julia
