If you want to get clicked row index on menu opening, the answer is NSTableView.clickedRow. Anyway this property is available only in specific moments, and usually just -1.

When is this index to be available? That's in NSMenuDelegate.menuWillOpen method. So you conform the delegate and implement the method on your class, and access the clickedRow property. It's done.

final class FileNavigatorViewController: NSViewController, NSMenuDelegate {
    let ov = NSOutlineView() // Assumed you setup this properly.
    let ctxm = NSMenu()
    override func viewDidLoad() {
        super.viewDidLoad()
        ov.menu = ctxm
        ctxm.delegate = self
    }
    func menuWillOpen(_ menu: NSMenu) {
        print(outlineView.clickedRow)
    }
}

Clicked row index is available until you click an item in the menu. So this also works.

final class FileNavigatorViewController: NSViewController {
    let ov = NSOutlineView() // Assumed you setup this properly.
    let ctxm = NSMenu()
    let item1 = NSMenuItem()
    override func viewDidLoad() {
        super.viewDidLoad()
        ov.menu = ctxm
        ov.addItem(item1)
        ov.target = self
        ov.action = #selector(onClickItem1(_:))
    }
    @objc
    func onClickItem1(_: NSObject?) {
        print(outlineView.clickedRow)
    }
}

I tested this on macOS Sierra (10.12.5).

Starting from OS X 10.11, Apple finally added a method to access clickedRow easily. Just subclass NSTableView and override this method and you'll get the clickedRow as far as I experienced.

func willOpenMenu(menu: NSMenu, withEvent event: NSEvent)

This needs subclassing, but anyway, the cleanest and simplest way to access clickedRow.

Also, there's a pairing method.

func didCloseMenu(menu: NSMenu, withEvent event: NSEvent?)
