How to start gesture programming in qt

I think you need to implement OpenCV.
With OpenCV is possible to obtain forms from images or webcam. It is not easy to use.

Can you look at PincArea and MultiPointTouchArea in QML ?

hi dhrendra but i cant get u what u r saying...

Do you want to write your own gesture or use the existing one provided by Qt like Pinch etc. First look at the Pinch and Pan gestures give by the Qt. You can look at MultiPointTouchPoints and PinchArea items given by QML. Also
QPanGesture, QPinchGesture, QSwipeGesture, QTapAndHoldGesture, and QTapGesture as given by Qt.If you want to write your own guesture look at QGuesture and QGuestureRecognizer classes. You need to subclass from QGuestureRecgonizer and write how do you want recognize the events as guestures.
Hope this helps.

If your plan is start do the project using Qt, you need to learn Qt and/or QML. Based on this you will be able to move forward with your gesture work. There is no jump start. You need to learn Qt.
