Your question is really not very clear. But if I understand you correctly, you want to know how to access properties like the count of the children of the real objects in your model object corresponding to the selection in the NSTreeController to which the NSOutlineView is bound. All you need to know for this is that the objects managed by the NSTreeController are wrappers of class NSTreeNode. From there the answers should be obvious from the documentation of this class.
