Interactive Filing System View?

I'm sure I'm being stupid and there's an easy way to do this, but can anyone share the script for an interactive view of the filing system, like a list view in the Finder on a Mac say, with rotating triangles and, if possible, open/closed folder symbols.

I thought the tree view widget might be the obvious thing to use but I can't see how.

At the moment I'm trying to do this by scripting a list field, but it feels like a lot of work for something that seems to be a common element of many apps.

Any suggestions please?
