    \inmodule QtLocation
    \ingroup QtLocation-routing
    \since 5.6

    \brief The QGeoRoute class represents a route between two points.

    A QGeoRoute object contains high level information about a route, such
    as the length the route, the estimated travel time for the route,
    and enough information to render a basic image of the route on a map.

    The QGeoRoute object also contains a list of QGeoRouteSegment objecs which
    describe subsections of the route in greater detail.

    Routing information is normally requested using
    QGeoRoutingManager::calculateRoute(), which returns a QGeoRouteReply
    instance. If the operation is completed successfully the routing
    information can be accessed with QGeoRouteReply::routes()
