|

All :class:`WlPointer` events before a :func:`WlPointer.frame()` event
|

compositor will send an optional :func:`WlPointer.axis_source()` event,

two :func:`WlPointer.axis()` events (horizontal and vertical) and

finally a :func:`WlPointer.frame()` event. The client may use this

information to calculate a diagonal vector for scrolling.
|
||
|
|
|
||
|
|
When multiple :func:`WlPointer.axis()` events occur within the same
|
||
|
|
frame, the motion vector is the combined motion of all events. When a
|
||
|
|
:func:`WlPointer.axis()` and a :func:`WlPointer.axis_stop()` event
|
||
|
|
occur within the same frame, this indicates that axis movement in one
|
||
|
|
axis has stopped but continues in the other axis. When multiple
|
||
|
|
:func:`WlPointer.axis_stop()` events occur within the same frame, this
|
||
|
|
indicates that these axes stopped in the same instance.
|
||
|
|
|
||
|
|
A :func:`WlPointer.frame()` event is sent for every logical event
|
||
|
|
group, even if the group only contains a single :class:`WlPointer`
|
||
|
|
event. Specifically, a client may get a sequence: motion, frame,
|
||
|
|
button, frame, axis, frame, axis_stop, frame.
|
||
|
|
|
||
|
|
The :func:`WlPointer.enter()` and :func:`WlPointer.leave()` events are
|
||
|
|
logical events generated by the compositor and not the hardware. These
|
||
|
|
events are also grouped by a :func:`WlPointer.frame()`. When a pointer
|
||
|
|
moves from one surface to another, a compositor should group the
|
||
|
|
:func:`WlPointer.leave()` event within the same
|
||
|
|
:func:`WlPointer.frame()`. However, a client must not rely on
|
||
|
|
:func:`WlPointer.leave()` and :func:`WlPointer.enter()` being in the
|
||
|
|
same :func:`WlPointer.frame()`. Compositor-specific policies may

For a :func:`WlPointer.axis()` event, the

movement direction of the entity causing the :func:`WlPointer.axis()`

this causes a :func:`WlPointer.axis()` vertical_scroll down event,

the physical direction is 'identical' - if a user's fingers on a

|
|
touchpad move down and this causes a :func:`WlPointer.axis()`

|
|
vertical_scroll up scroll up event ('natural scrolling'), the
|

|
physical direction is 'inverted'.
|
||
|
|
|

|
|
A client may use this information to adjust scroll motion of

|
components. Specifically, enabling natural scrolling causes the content
|

|
|
to change direction compared to traditional scrolling. Some widgets
|
||

|
like volume control sliders should usually match the physical direction
|

regardless of whether natural scrolling is active. This event enables
