How to access 3 dimensional array from C++ to QML

flowery

Window {
visible: true
property var items :[[["blue", "green","yellow"],["red","black"]], [["black","grey"],["white","pink"]]]
property var subItems:[]
MouseArea {
anchors.fill: parent
onClicked: {
Qt.quit();
}
}

Row{
    spacing:2
    Repeater{
        id: mainArr
        model: items

        Item{
            width: 200
             height: 150

            Column{
                spacing : 2
              //  anchors.horizontalCenter: parent.horizontalCenter
                height: parent.height
                Repeater{
                    model:items[index]
                    Rectangle{
                        width: 200
                        height: 50
                        color: "blue"

                    Row{
                        anchors.horizontalCenter: parent.horizontalCenter
                        //width: 50 ; height: 50; //color: modelData
                        Text{ text: modelData[0]}
                        Text{ text: modelData[1]}
                        Text{ text: modelData[2]}
                    }
                    }
                }
            }
        }
    }
}

This is the sample Qml program , whereas I want to read this items array from QT C++.I tried with QList<QList<QVariant>>> datatype ,stored the values and returned in data() function as QVariant::fromValue(items).But I am not getting the values in qml instead just printing the datatype.
