how to get editpart for semantic element or how to select semantic element in diagram [message #77550]

Hi.

I have found many ways to select elements in diagram but all those
methods expect editpart object[s] on input (encapsulated into
IStructuredSelection). I have a list of semantic elements and I would
like to select corresponding editparts in diagram editor, so:
how can I get editpart for semantic element or
or to directly select semantic element in given diagram.

Regards,
Seweryn

Seweryn,

Take a look at the method
IDiagramGraphicalViewer.findEditPartsForElement(String elementIdStr,
Class editPartClass). Search for references to find an example of its
use in the CanonicalConnectionEditPolicy.

Cherie

Thank you very much, it works nice. Only one more question, why you use
Element ID Strings as keys in ElementToEditPartsMap instead of simply
Element object (by identity)?

tips for others:

1. get IDiagramGraphicalViewer:
for example
((IDiagramWorkbenchPart)yourDiagramEditor).getDiagramGraphic alViewer()

2. get all parts for your semantic element:
List editParts = diagramGraphicalViewer.findEditPartsForElement(
EMFCoreUtil.getProxyID(port),
PortEditPart.class
);

List editParts = diagramGraphicalViewer.findEditPartsForElement(
EMFCoreUtil.getProxyID( <model>),
<ModelEditPart>.class
);

Great, but I don't know exactly what <model> do I have and what kind of
<ModelEditPart>.class should I use - I only know that someone has
selected something - any ideas?

thanx

Your solution is ok.
I forgot that when you give parent class as modelEditPart, all
childClass are accepted
