I'm trying to use a (subclass of a) TreePresenter that is populated with
FileReferences. I see that the current selection is, reasonably enough, a
TreeNodePresenter, so I'm assuming that to set a selection programatically, I'm
going to have to find the right TreeNodePresenter.
So I've assumed a method allItemsDo: that I'm trying to write on my subclass of
TreePresenter that will iterate through all of the TreeNodes and let me do
stuff, such as looking at their #content to see if this is a node that I'm
interested in.
But I can't! The #roots method of TreePresenter doesn't give me the root
TreeNodePresenters; it gives me the file references that they contain. How do I
iterate over the TreeNodePresenters? Or am I going about this in entirely the
wrong way?
