    Default Multi-touch sensing in Qt

    Hi All,
    I am working on Embedded Linux platform with TI-Sitara porcessor.
    I want to use gesture sensing using Qt for zoom-in, zoom-out, flick etc.
    Where i can found the relevant documentation.
    Currently i have Qt 5.2 installed on windows PC, what study/basics i can do using this for multi-touch sense?

    Thanks in advance.

    Depends on what kind of UI framework you are planning to use.

    In QtWidgets you can get QTouchEvents through the widget's event() method, in QtQuick there are Flickable, PinchArea and MultiPointTouchArea

    Anda_skoa Thanks for reply,
    I am planning to use Linux OS, till now i was focusing on Qt Creator and UI-Designer of Qt to build the applications.
    Can i use Qt-Quick for Linux based embedded platforms (I want to use flick, pinch-zoom in/out gestures)?
    Please bear with me if i am asking any stupid question, I ma new to Qt.

    Thanks in advance,

    I doubt that is relevant, I am not aware of any platform that only support widgets or qtquick.
    The latter requires OpenGL capable hardware though.

    So you'll need to find out if your hardware has a sufficiently 3D capable GPU and your OS the necessary driver support for that.
