Expand description

axis click event

Discrete step information for scroll and other axes.

This event carries the axis value of the wl_pointer.axis event in discrete steps (e.g. mouse wheel clicks).

This event is deprecated with wl_pointer version 8 - this event is not sent to clients supporting version 8 or later.

This event does not occur on its own, it is coupled with a wl_pointer.axis event that represents this axis value on a continuous scale. The protocol guarantees that each axis_discrete event is always followed by exactly one axis event with the same axis number within the same wl_pointer.frame. Note that the protocol allows for other events to occur between the axis_discrete and its coupled axis event, including other axis_discrete or axis events. A wl_pointer.frame must not contain more than one axis_discrete event per axis type.

This event is optional; continuous scrolling devices like two-finger scrolling on touchpads do not have discrete steps and do not generate this event.

The discrete value carries the directional information. e.g. a value of -2 is two steps towards the negative direction of this axis.

The axis number is identical to the axis number in the associated axis event.

The order of wl_pointer.axis_discrete and wl_pointer.axis_source is not guaranteed.
