# systemTabletID

The index of the tablet device connected to the system.

## Declaration

```swift
var systemTabletID: Int { get }
```

## Discussion

Discussion If multiple tablets are connected to the system, the system-tablet ID is incremented for each subsequent one. If there is only one tablet device, its system-tablet ID is zero. This property is valid for mouse events with the subtype NSTabletProximityEventSubtype or NSTabletProximity events.
