Maybe for the simple cases...

There's no good way to do this because the model determines when things are removed. For example, let's say the library you're using creates a model that is mapped onto a database column. If something in the database is removed, the model updates it's state as well. At that point, the model doesn't know what was there anymore so there's no way for you to know either.

That being said, if you can rely on the JList's model returning elements that you can interpret, you can keep your own model and listen to ListDataEvents like you have been doing. Update your local model as you see fit.
