Hello,
I am trying to work out how to get an NSTreeController
to display only certain objects. As far as I can see,
mmalc's FilteringArrayController at
http://homepage.mac.com/mmalc/CocoaExamples/controllers.html
does exactly what I want to do except that
FilteringArrayController is a subclass of
NSArrayController and I would need to subclass
NSTreeController.
However, FilteringArrayController overrides
NSArrayController's -arrangeObjects: method - and
NSTreeController has no such method to override.
Does anybody know how to do something similar for
NSTreeController? The docs mention overriding
insertObject:atArrangedObjectIndexPath: but it says
this for NSArrayController too.
Many thanks for any hints,
Keith
