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: https://raw.github.com/xiangzhai/myblog/master/MTX11-Note/mtm.jpg 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 http://sourceforge.net/apps/mediawiki/linuxwacom/index.php?title=Dual_and_Multi-Monitor_Set_Up But I prefer to use read /dev/input/eventX file descriptor based on Linux Multi-Touch Protocol B https://www.kernel.org/doc/Documentation/input/multi-touch-protocol.txt 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 https://raw.github.com/xiangzhai/myblog/master/MTX11-Note/MT.conf Is there a common way provided by Qt5? Please someone give me some advice, thanks a lot! Best Regards, Leslie
