to send relative motion events.</p>

<p>The (unstable) protocol consists of a RelativePointerManager which<br />

creates RelativePointers for a given Pointer. This interface currently<br />

only has one event to report the relative motion. It carries the delta,<br />

the non-accelerated-delta and a timestamp in microsends granularity.</p>

<p>On the server side the implementation is mostly internal. Once a<br />

RelativePointerManagerInterface is created one can send relative motion<br />

events through the SeatInterface. The SeatInterface takes care of<br />

sending it to the responding RelativePointerInterface. The protocol does<br />

not restrict the sending of "normal" and relative motion events. Thus it<br />

can be combined in any way one wants. This allows to have a rather<br />

simple implementation. A user of the SeatInterface can just start to<br />

feed the relative motion events (if the information is available) to the<br />

SeatInterface together with the pointer events.</p>

<p>On client side a new RelativePointerManager and RelativePointer class<br />

are added. The RelativePointerManager creates the RelativePointer for a<br />

given Pointer. The event sent to RelativePointer is transformed in a<br />

normal signal.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>rKWAYLAND KWayland</div></div></div><br /><div><strong>BRANCH</strong><div><div>relative-pointer</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D2978" rel="noreferrer">https://phabricator.kde.org/D2978</a></div></div><br /><div><strong>AFFECTED FILES</strong><div><div>autotests/client/test_wayland_registry.cpp<br />
