RCP how to make TreeViewer non editable [message #1783803]

Hi all!

I am a university student making my last university project in EMF, so I am new to this technology. I am developing different RCP tools based on different metamodels. In one of the tools I need to make the properties view editable while the TreeViewer must keep read-only. I find the way to make all the resource non-editable doing this in the handleActivate method of the Editor:

Resource res = editingDomain.getResourceSet().getResource().get(0);
editingDomain.getResourceToReadOnlyMap().put(res, true);

But I am unable to make just the TreeViewer non editable.

Any help??

Thanks a lot!

Is this for an exercise? I don't see the practical goal. How is this actually useful?

In the end, the model is modified by commands created by the editing domain, mostly delegating to the item providers for creation. Some commands are used by the properties view and some are used by the tree structure, but in the end, the same command might be used in both places, so selectively disabling a command used to modify the tree structure verses a command used to modify properties in the properties view isn't entirely trivial; it depends on your model and on which properties you support. Likely command that modify containment/container features are used for the tree structure; those that modify attributes and cross references are used in the properties view, so perhaps that will suffice.
