NSEvent got a float named pressure:


NSEvent


- (float)pressure


Returns a value between 0.0 and 1.0 indicating the pressure applied to the input device (used for appropriate devices). For devices that aren't pressure-sensitive, the value is either 0.0 or 1.0. Raises anNSInternalInconsistencyException if sent to a non-mouse event.
