Ken,
Thanks for trying to help me out. I tried to follow your advice, but I must not
have completely understood it.
I changed the relevant method to this:
func outlineView(
_outlineView: NSOutlineView!,
objectValueForTableColumn tableColumn: NSTableColumn!,
byItem item: AnyObject!
) -> AnyObject!
{
let node = getDocumentNodeFrom( item )
return node
}
And in the particular NSTextFieldCell, I made sure “Bind to Table Cell View”
was checked, and I set the model key path to objectValue.title. I’d love to
attach a screenshot of what I’ve done in Xcode, but I haven’t been able to make
a JPEG small enough to get past the mailing list’s 25K limit.
In case it matters, here’s part of the declaration of DocumentNode:
import Foundation
class DocumentNode : NSObject {
var title: String
var content: NSAttributedString
var children: [DocumentNode]
When I run my program, the outline view still shows disclosure triangles but no
titles for the text view cells.
