How do I update a column label provider when using ObservableValueEditingSupport? [SOLVED] [message #1755167] Tue, 28 February 2017 16:42

I have a TableViewer where the input is an ObservableList I create with EMFEditProperties.

The TableViewer also has a TableViewerColumn which uses ObservableValueEditingSupport.

This works, I can edit the content in the column and the value gets correctly propagated to my EObjects in my list.

However, currently I use a simple CellLabelProvider which does NOT get updated. Is there a corresponding LabelProvider I can use, or how do I update the LabelProvider by myself?

EDIT: I didn't see the forest for the trees, as so often Embarrassed

It's very simple:

final ObservableListContentProvider cp = new ObservableListContentProvider();
tableViewer.setContentProvider(cp);
final IObservableMap map = EMFProperties.value(MyPackage.eINSTANCE.getFoo_Bar()).observeDetail(cp.getKnownElements());
viewerColumn.setLabelProvider(new ObservableMapCellLabelProvider(map));
