Currently, the "wlr_event_pointer_axis" event stores low-resolution values in its "delta_discrete" field. Low-resolution values are always multiples of one, i.e., 1 for one wheel detent, 2 for two wheel detents, etc. In order to simplify internal handling of events, always transform in the backend from the low-resolution value into the high-resolution value. The transformation is performed by multiplying by 120. The 120 magic number is used by the kernel and it is exposed to clients in the "WLR_POINTER_AXIS_DISCRETE_STEP" constant. |
