How does a Qt desktop application on Mac OS receive and respond to multi-touch guestures
-
For example, how can i select a word in QTextEdit by clicking the trackpad with three fingers ? Should I use cocoa API?
-
anybody help！

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.

bad news! task is urgent, but i am not familiar with cocoa and object-c!
