Hi,
I'm transitioning my app from using a NSOutlineView data source to
NSTreeController.
I want to start editing a row programmatically, so I need to call
editColumn:row:withEvent:select:, but then I need the row index. I
can get that with rowForItem:, but as far as the NSOutlineView is
concerned, it deals with NSTreeNodes. So I need a way to get the
NSTreeNode for a given object.
+ treeNodeWithRepresentedObject: doesn't help since it creates a new
node.
This seems like something that should be easy, but I can't figure it
out.
AFAIK, there's no way to do this other than employing somewhat ugly
and inefficient hacks such as iterating through the entire tree
structure looking for the node whose represented object is the object
you're looking for.
In my opinion, NSTreeController is still limited enough that it raises
some questions about whether it really should be used.
