EMF-Edit - mapping features to table columns [message #1736711]

Looking at http://git.eclipse.org/c/efxclipse/org.eclipse.efxclipse.git/tree/demos/org.eclipse.fx.demo.contacts.app/src/org/eclipse/fx/demo/contacts/views/ContactsTableView.java

which is the line which specifies which feature of the EObject is shown in which TableColumn?

I can see that, for editing, this is in the line

firstNameCellFactory.addCellEditHandler(new EAttributeCellEditHandler(ContactsPackage.eINSTANCE.getContact_FirstName(),
				editingDomain));

But without editing?

The line which maps the feature in the EMF object to the table column is this:

AdapterFactoryTableCellFactory<Object, Object> firstNameCellFactory = new AdapterFactoryTableCellFactory<>(adapterFactory, 0);

It is the index '0' which selects out the feature of the EMF object, and in order to map the index to the feature, AdapterFactoryTableCellFactory delegates to any AdapterFactory supporting ITableItemLabelProvider.

The default AdapterFactory generated by EMF.Edit does not support ITableItemLabelProvider. So in order to display an EMF object in a table, as per the Contacts demo, add support for ITableItemLabelProvider into the AdapterFactory, following http://eclipseo.blogspot.co.uk/2014/11/displaying-your-emf-model-on-tableviewer.html
