well, objects are great for mutable state encapsulation. a view , a scrollbar, a listview, etc are all highly mutable ( 60 times a second) and you can very well organize all of them in a 2 or 3 level hierarchy of inheriting classes ( a listview is a kind of view).

but, you may probably as well organize them as nested property sets each of which containing the other ( like a listview contains a view part and a list part). Not sure the result will be as elegant, but i'm curious to look at the result.
