5.3.1 Pointer event handling for indirect touch devices
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Indirect touch devices are expected to generate pointer events. In contrast with
direct touch devices, as stated below, the server will not generate pointer
events on behalf of indirect touch devices. Further, pointer events from
indirect touch devices are delivered independently of touch events.
DependentTouch and SemiMultitouch devices may generate pointer events by mapping
one touch sequence to the pointer. In these cases, events for both the pointer
and its associated touch sequence will have the PointerEmulated flag set.
Indirect touch devices are expected to generate pointer events and no
pointer emulation is performed. However, the pointer event may be generate
in the driver by mapping one touch sequence to the pointer. In these cases,
events for both the pointer and its associated touch sequence will have the
PointerEmulated flag set.
When the cursor of an attached master pointer of an indirect device leaves the
window of a touch grab or selection, or when a client activates a pointer grab
