      For example, how can i select a word in QTextEdit by clicking the trackpad with three fingers ? Should I use cocoa API?

          If you really just want the touch points on the trackpad you have to use MAC OS API. That's something Qt doesn't support (yet?) ...

          For touchscreens there is a "QTouchEvent":http://qt-project.org/doc/qt-5.0/qtgui/qtouchevent.html#touchPoints class available which provides you with the needed information.
