 /*!
    \class QGesture
    \since 4.6

    \brief The QGesture class represents a gesture, containing all
    properties that describe a gesture.

    QGesture objects are delivered to widgets and
    \l{QGraphicsObject}{QGraphicsObject}s with a QGestureEvent.

    The class has a list of properties that can be queried by the user to get
    some gesture-specific arguments (i.e. an scale factor of the Pinch
    gesture).

    When creating custom gesture recognizers, they might add new dynamic
    properties to the QGesture object, or custom gesture recognizer developers
    might subclass the QGesture class (or any of classes that derive from it)
    to provide additional information.

    \sa QGestureEvent, QGestureRecognizer
