Hi,

how can I get the EditPart of a semantic element? For example a Class or a Port?

Is there a tutorial that explains how to create EditPart programmatically from newly created semantic elements and then show them in the editor?

Thanks in advance, star123

Hello,

Thanks bachra04 for your reply.

Unfortunately, this is not what I am looking for. Sad

But, I'll try to give a good representation for my problem.

What I want to do exactly is when a diagram element is clicked, all its outgoing connections change their color.

I have already done a mouse listener to the XXXeditpart, when the diagram element is pressed I get all its outgoing connections -Elements-.
But the problem is how to get their Diagram element to be able to update their color?????

I've searched all over the internet and I haven't found any tutorial or information concerning my problem. Sad

Any help will be highly appreciated Smile

Thank you in advance Smile

If your EditParts are created with the edit part factory, you can use

org.eclipse.gef.EditPartViewer.getEditPartRegistry()

This is pure GEF. Since you mention "semantic model", I'm not sure
whether you may refer to GMF? In that case, there are two models: a
semantic (or domain) model and the notation (or graphical model). The
latter one is the model of the edit part, while the first one is
associated with the notation model. GMF provides a mechanism for that
matter, just have a look at

org.eclipse.gmf.runtime.diagram.ui.parts.IDiagramGraphicalVi ewer.findEditPartsForElement(String,
Class)

If you cannot use the edit part registry nor GMF's mechanism, you may
want to use a ReverseLookupManager I've written for GEF3D. You'll find
that in the SVN at

https://dev.eclipse.org/svnroot/technology/org.eclipse.gef3d /trunk/org.eclipse.gef3d.ext/src/java/org/eclipse/gef3d/ext/ reverselookup/

Cheers,
Jens
