Declaration
var pointingDeviceID: Int { get }Discussion
This index is significant for multimode (or Dual Tracking) tablets that support multiple concurrent pointing devices; the index is incremented for each pointing device that comes into proximity. Otherwise, zero is always returned. This property is valid for mouse events with subtype NSTabletProximityEventSubtype or an event of type NSTabletProximity.
