Is there a way to listen to visible table items of an SWT Table?
So that when the number of items changes a listener is informed.
(A solution with JFace table viewer would also help.)

Regards,
Kai

Thanks, Tom. But I guess I was a bit imprecise with my question, my fault.
I am looking for a way to listen what items are at all inside the table. So when items are added or removed a listener is informed.

Regards,
Kai

There's none but might I suggest to use an IObservableList
(WritableList) as your viewer input, a ObservableListContentProvider
add/remove your domain objects there on the WritableList (instead of
calling the viewer pendents) => You can then register a listener on the
WritableList and get informed.
