cocoa - NSTableView: detecting a mouse click together with the row and column

I'm trying to detect when a mouse click occurs in an NSTableView, and when it does, to determine the row and column of the cell that was clicked.

So far I've tried to use NSTableViewSelectionDidChangeNotification, but there are two problems:

  1. It only triggers when the selection changes, whereas I want every mouse click, even if it is on the currently selected row.
  2. The clickedRow and clickedColumn properties of NSTableView are both -1 when my delegate is called.

Is there a better (and correct) way of doing this?

There is a simple way.

Tested with Swift 3.0.2 on macOS 10.12.2 and Xcode 8.2.1

Let

tableView.action = #selector(onItemClicked)

Then

@objc private func onItemClicked() {
    print("row (tableView.clickedRow), col (tableView.clickedColumn) clicked")
}
