Below is the code for "OutlineView" (on your machine in
Developer/Examples/AppKit/OutlineView). It presents an expandable view of
everything on your machine from / (root).
How would I point this app to look at a specific folder (say "Library")
located on the desktop?
I've experimented, but can't figure out how to identify the path as this:
* /Users/k2/Desktop/Library*
as opposed to
* / (root).*
I don't want to see everything on my machine, just what's in the folder.
I appreciate your your help.
