AFAIK, a view does not make changes.

If they're both working on the same model, and are listening for changes,
they should stay in synch automatically. Your editor would change the model
and both the editor's editparts and the view's editparts would be notified.
BTW, the view can make changes. In the logic example, you can create new
parts in the outline view, increment/decrement LED values, reparent parts,
reorder parts (change z-order to determine which part paints on top), etc.

has a comment that says: "Abstract base implementation of all workbench
views." Please correct me if I am wrong. I am still learning the framework.
Thanks!

I found the right question:
"How can I make a View (ViewPart) respond to changes (i.e. figure =
selections) in the Editor?"
It would help to know where in the editor's code to do this or what does =
the editor (code) need (i.e. interfaces)
Thank you!

So, the EditorPart should hook a SelectionProvider into the site's =
Selection Service. The ViewPart should listen to the workbench's =
SelectionSErvice by adding a selection listener.
You'll get editor selection, but also other selection's you'll have to =
ignore.
