How to set the QML property MapPolyline Path

Question

I have an object MapPolylinein my QtQuick project. I need to change the path property from a C ++ file, but I don't know how to do this.

My qml - File:

MapPolyline {
    id: mapline
    objectName: "MapLine"
    line.width: 5
    line.color: "green"
    path:
    {[
        { latitude: 47.219791, longitude: 9.546032 },
        { latitude: 47.219657, longitude: 9.542508 },
        { latitude: 47.2194446, longitude: 9.5437876 }
    ]}
}

And now I want to change the contents of the path property from a C ++ file.

Thanks for the help!
