## Discussion

This property contains an array of three <doc://com.apple.documentation/documentation/Foundation/NSNumber> objects. Each object encapsulates a `short` value that vendors may return for various reasons; see the vendor documentation for details.This method is valid for mouse events with subtype [`NSTabletPointEventSubtype`](/documentation/AppKit/NSTabletPointEventSubtype) and for [`NSTabletPoint`](/documentation/AppKit/NSTabletPoint) events.
