I am sure the Qt multitouch function works by using the MTF image posted at http://repo.meego.com/MeeGo/builds/1.0.80/1.0.80.14.20100810.1/handset/images/meego-handset-ia32-netbook-mtf/ However, per the Qt source code qt-everywhere-opensource-src-4.7.0-tp/src/gui/kernel/qapplication_x11.cpp, it seems the QApplicationprivate::initializeMultitouch_sys() only recognizes devices /dev/input/eventX which reports absolute coordination values, so my driver (dual touch panel) registers two device nodes, then it can work with the provided Qt multitouch sample apps (e.g. fingerpaint).

Even though Xorg evdev driver isn't yet capable of detecting multitouch-capable devices (at least from my understanding)? If multitouch on Qt does already work, how do we tell Qt about our multitouch device, is there some non-default setting that needs to be configured?
