Yes, exactly like that.
And i want to find a convenient approach how to achieve that. Means ,
that from one side we having
a container (list, inspector, panel, window etc) and from other side,
we having a model which is a collection of items.
And i want to find a way, how an object, which you want to represent
in a container, could pick a most appropriate form
of its representation, BUT depending on a nature of container.

I am not convinced myself that such way is feasible either. You tell :)
Usually, in most cases, a container dictating how its items should be
displayed and behave.
And usually, a model knows more than a little about items it contains
(for instance a class methods pane contains only methods, not
arbitrary objects).
