It is my understanding that an NSOutlineView is only 'populated' by
using its Delegate Methods.
My manager (a Windows guy with no Cocoa) claims the NSOutlineView
can be directly manipulated as in add root, add child etc.
NSOutlineView does not have any methods for manipulating the tree of
items displayed therein, because conceptually speaking it has no
items. They belong to the datasource, and the outline view asks for
them anew every time it needs to display a region of itself.
NSTreeController does offer some direct manipulation functionality,
and its support for bindings will make it easy to use with
NSOutlineView—that is until you run into one of the many infamous
NSController bugs or limitations. But often you really want to make
your changes to the model rather than the controller, particularly
if your model is already in the same hierarchy you intend to display
in the outline view. In that case your controller object mightn't
need any hierarchy management of its own, rather only serving as a
connection point between the model and view.
