Hi qt developers && users,

Does Qt5 support multiple touch devices for X Window?

For example, 9 projected capacitive touch screen devices experienced as
a super big touch screen, shown as below link:

When I touched the FIRST screen, X Window rendered the mouse in the
FIRST monitor, but touched the second or others, X Window still rendered
it in the FIRST monitor, X Window fail to transform the coordinate matrix.

I sent an email to xorg-devel
http://lists.x.org/archives/xorg-devel/2013-October/038263.html and a
nice people named Peter gave me some advice about XSetWacom

But I prefer to use read /dev/input/eventX file descriptor based on
Linux Multi-Touch Protocol B
And handled multiply touch devices simultaneously, when got
ABS_MT_POSITION_X and ABS_MT_POSITION_Y, transformed the corrdinate
based on the touch device (Monitor) logical position

Is there a common way provided by Qt5? Please someone give me some
advice, thanks a lot!

Best Regards,
