<description summary="protocol for relative pointer motion events">
|
|
This protocol specifies a set of interfaces used for making clients able to
|
|
receive relative pointer events not obstructed by barriers (such as the
|
|
monitor edge or other pointer barriers).
|
|
|
|
To start receiving relative pointer events, a client must first bind the
|
|
global interface "wp_relative_pointer_manager" which, if a compositor
|
|
supports relative pointer motion events, is exposed by the registry. After
|
|
having created the relative pointer manager proxy object, the client uses
|
|
it to create the actual relative pointer object using the
|
|
"get_relative_pointer" request given a wl_pointer. The relative pointer
|
|
motion events will then, when applicable, be transmitted via the proxy of
|
|
the newly created relative pointer object. See the documentation of the
|
|
relative pointer interface for more details.
|
|
|
|
Warning! The protocol described in this file is experimental and backward
|
|
incompatible changes may be made. Backward compatible changes may be added
|
|
together with the corresponding interface version bump. Backward
|
|
incompatible changes are done by bumping the version number in the protocol
|
|
and interface names and resetting the interface version. Once the protocol
|
|
is to be declared stable, the 'z' prefix and the version number in the
|
|
protocol and interface names are removed and the interface version number is
|
|
reset.

A wp_relative_pointer object is an extension to the wl_pointer interface
|
|
used for emitting relative pointer events. It shares the same focus as
|
|
wl_pointer objects of the same seat and will only emit events when it has
|
|
focus.

<event name="relative_motion">
|
|
<description summary="relative pointer motion">
|
|
Relative x/y pointer motion from the pointer of the seat associated with
|
|
this object.
|
|
|
|
A relative motion is in the same dimension as regular wl_pointer motion
|
|
events, except they do not represent an absolute position. For example,
|
|
moving a pointer from (x, y) to (x', y') would have the equivalent
|
|
relative motion (x' - x, y' - y). If a pointer motion caused the
|
|
absolute pointer position to be clipped by for example the edge of the
|
|
monitor, the relative motion is unaffected by the clipping and will
|
|
represent the unclipped motion.
|
|
|
|
This event also contains non-accelerated motion deltas. The
|
|
non-accelerated delta is, when applicable, the regular pointer motion
|
|
delta as it was before having applied motion acceleration and other
|
|
transformations such as normalization.
|
|
|
|
Note that the non-accelerated delta does not represent 'raw' events as
|
|
they were read from some device. Pointer motion acceleration is device-
|
|
and configuration-specific and non-accelerated deltas and accelerated
|
|
deltas may have the same value on some devices.
|
|
|
|
Relative motions are not coupled to wl_pointer.motion events, and can be
|
|
sent in combination with such events, but also independently. There may
|
|
also be scenarios where wl_pointer.motion is sent, but there is no
|
|
relative motion. The order of an absolute and relative motion event
|
|
originating from the same physical motion is not guaranteed.
|
|
|
|
If the client needs button events or focus state, it can receive them
|
|
from a wl_pointer object of the same seat that the wp_relative_pointer
|
|
object is associated with.
