Description
MaxTapXDif indicates maximum distance in y-coordinate between EVT_POINTER_DOWN and EVT_POINTER_UP event. This function is used to set the maximum distance in y-coordinate between EVT_POINTER_DOWN and EVT_POINTER_UP event. This is one of the criteria to be satisfied for single tap detection. This can be used in conjunction with the max tap distance; when either of the criteria is met, it will count as a tap.
