I want to be able to disable selection on certain elements in the Ecore Editor dynamically.

How can I do that?

You could listen to selection changes and unselect things you don't want to be selected. But I doubt users would find that intuitive behavior; I've need seen a tree that doesn't allow certain things to be selected...

Hi Ed,

Thanks for your answer.

But is it not possible at all to disable a TreeItem in the TreeViewer?

There is only "setGrayed" method available on any TreeItem?

But not "disable" or something similiar?
