Note: copying this to the eclipse.platform newsgroup.

I think you can use an ArrayContentProvider to do what you want; it
should handle any array or Collection as input.

Hope this helps,

The viewer won't update themselves when the underlying list changes
(because Java-List don't inform about changes). To make this possible

a) ArrayContentProvider:
List l = ...
viewer.setContentProvider(new ArrayContentProvider());
viewer.setInput(l);

....
l.add(new ...)
viewer.refresh();

b) Databinding with ObservableListContentProvider

IObservableList l = ...
viewer.setContentProvider(new ObservableListContentProvider());
viewer.setInput(l);

l.add(new ...);

If you refresh manually don't forget to use listviewer.refresh(true) to update labels as well.
