Displaying a list of views

Answer 1

If you can require Leopard, take a look at NSCollectionView. The API is a little weird but it's pretty powerful once you get the hang of it.

Answer 2

You could also use NSTableView and create a custom subclass of NSCell to render the content.

Answer 3

I've been told that I can use NSMatrix to achieve this.

You can't. NSMatrix uses cells, not views.
