I'd like the app run on 10.4. For the purpose, would you tell me the
following things?
1. Is NSTreeController's selectedNodes the same as
NSTreeController's selectedObjects?
2. How do you implement functions for 10.4, instead of using
NSTreeNode class which is introduced on 10.5?
I do especially like to know how to implement codes like
NSTreeNode's parentNode and indexPath.
Having spent a lot of time working with NSTreeController on 10.4 I can
tell you that if you want to use it for anything more than very basic
things, you will find that it is buggy, unreliable and many of the
features are only available in private methods.
Leopard's implementation is a dream in comparison and if you want to
do extensive work with NSTreeController then if possible I highly
recommend targeting Leopard. You will not regret it.
