Display menu on NSTableView if a row is selected

I have a menu on the outlet of an NSTableView. It will show the menu when I right click on the Table View, but I don't want to show the menu if there is no row selected. How can I stop the menu from showing when I right click and there is no row selected?

I have tried the:

validateMenuItem

but it never gets called

I have tried NSMenuDelegate and its

func menuWillOpen(_ menu: NSMenu) { }

and

func menuNeedsUpdate(_ menu: NSMenu) { }

but none of them return anything that I can set to DONT show menu IF...

The suggested duplicate asks to prevent displaying the contextual menu when clicking on a specific cell. This question is about preventing the menu to show when no ROW is selected.

Solution

  • It was pretty easy:

    Implement

    NSMenuDelegate

    and add this method:

    func menuWillOpen(_ menu: NSMenu) {
        if myTableView.selectedRow < 0 {
            menu.cancelTrackingWithoutAnimation()
        }
    }
