4Subject: [PATCH 5/5] pointers: detect a change of pointer-device used and set
5 "touchscreen-pointer" as found in xfconf
6MIME-Version: 1.0
7Content-Type: text/plain; charset=UTF-8
8Content-Transfer-Encoding: 8bit
9
10To detect pointer device in use the DevicePresence-, DeviceMotionNotify- and
11DeviceButtonPress-events are handled. Tests showed that by repopenning and
12closing the pointer devices (e.g when another setting was modified), the events
13stopped working. Therefore all pointer devices are opened only once and managed
14in a hash table.
