To find out if someone only "tap to click" you could use

func pressureChange(with event: NSEvent) 

在NSView上的NSViewController中.

in your NSViewController on NSView.

如果仅轻按"某人，则不会触发该功能.如果单击，您将获得压力变化的压力水平.

If someone only "tap" the function will not be triggered. In case of a click you will get the pressure level on pressure change.

        super.pressureChange(with: event)
        print("pressure \(event.pressure)")
    }
