Hi,
I'm trying to create a Navigator View (preferably using Eclipse CNF) for my RCP application GMF-based (over an EMF model, of course).
My needs are:
- display only my model objects in the tree
- having them represented in a GMF Diagram
- having them bounded with diagram and property sheet
- the input has to be not resource-based (e.g., a file), but instead created via Java code
Based on book "Eclipse Modeling Framework" by Eclipse Series, I've initially created a simple ViewPart and a TreeViewer with the following code:
adapterFactory = new ComposedAdapterFactory(ComposedAdapterFactory.Descriptor.Reg istry.INSTANCE);
adapterFactory.addAdapterFactory(new ResourceItemProviderAdapterFactory());
adapterFactory.addAdapterFactory(new [MyProjectName]ItemProviderAdapterFactory());
adapterFactory.addAdapterFactory(new ReflectiveItemProviderAdapterFactory());
treeViewer.setContentProvider(new AdapterFactoryContentProvider(adapterFactory));
treeViewer.setLabelProvider(new AdapterFactoryLabelProvider(adapterFactory));
and then I've set the TreeViewer input with my EMF model.
This way I can see my (code created) model objects, but they are not linked with PropertySheetPage. Besides, if I open a GMF Diagram filled with my objects, I'm not able to have the tree refreshed if I add some object graphically.
So, i'm lost now.....is this the right way to suite my needs?

I'm not sure how well GMF works without a workspace. In fact, I'm not
sure it does.

Look at the generated EMF editor to see how it hooks to the property
sheet page. E.g., getAdapter.

Maybe you can look at how Ecore Tools solves this problem. The editor
would need to share the same instance objects as are used in the CNF.
