Thanks for reply. In fact, what I want to know is how QT decide to use the
below gesture recognize if there were more than one gesture recognizer? Say,
if QT uses geis, then also means that we must have grail support inside. But
anyway, it might be only some switch from build-time, and if user decided to
use someone recognizer that means of course they also need all backend
stuffs. Thanks.

With a glance look on them, it's more *like* touchegg is one UI of ginn
because touchegg can use those info/method from ginn to do those things it
is described from that meeting minutes.
And both ginn and touchegg mainly target for those app which doesn't support
MT natively?

Thanks again for your answers.
