[Qt-interest] Multi Gesture

[Wathek LOUED]

Sean,

Yes but the problem is that since that QGestureRecognizer doesn't free the
QGesture and it uses always the same QGesture it only resets it I cannot
have two (or more) same gestures at the same time.

Let's say that the gesture is a Tap and Hold so it needs about 700ms without
moving to recognize the gesture. So first touched Point the
GestureRecognizer setted the QGesture parameters (Position, Timer, etc). At
400ms a second Touched Point arrived, the GestureRecognizer cannot do
anything since it's busy with the first one. You see ?
