Как в QMK в ListView сделать центрирование по центру?

We recommend hosting TIMEWEB

Stable hosting, on which the social network EVILEG is located. For projects on Django we recommend VDS hosting.

ListView{
id:myList
anchors.horizontalCenter:parent.horizontalCenter
}

Это не помогает.
Ниже мой код

Rectangle{
        //Flickable {
        //contentX: 100
        id: rectangleForListView
        y: parent.height * 0.15
        height: parent.height * 0.7
        anchors.left: parent.left
        //anchors.leftMargin: parent.width * 0.10
        anchors.right: parent.right

        ListView
        {
            id: myListView1
            highlightRangeMode: ListView.StrictlyEnforceRange
            anchors.fill: parent
            anchors.horizontalCenter:parent.horizontalCenter
            orientation : ListView.Horizontal
            snapMode: ListView.NoSnap
            //spacing: myListView1.width * 0.06
            contentX: 100
            contentWidth: 100
            model: page_model

            delegate:
                Item
            {
                id: itemDelegate
                width : myListView1.width < myListView1.height ? myListView1.width * 0.7 : myListView1.height * 1
                height: myListView1.width < myListView1.height ? myListView1.width * 1 : myListView1.height * 0.7
                //height: myListView1.height * 1
                //width: myListView1.width * 0.7
                Rectangle
                {
                    anchors.fill: parent
                    anchors.leftMargin: myListView1.width * 0.06
                    Label
                    {
                        id:site_name
                        anchors.top: parent.top
                        anchors.centerIn: parent
                        text: namesite
                    }

                    Rectangle {
                        id: rec1
                        color: "grey"
                        anchors
                        {
                            top:site_name.bottom
                            left: parent.left
                            right:parent.right
                            bottom:parent.bottom
                        }
                        Label
                        {
                            id:lbl_url
                            anchors.centerIn: parent
                            text: url
                        }
                        Image {
                            anchors.fill: parent
                            id: idImageUrl
                            //source: "qrc:/icons/append.png"
                            source: screen
                            fillMode: Image.Stretch
                        }
                    }


                }
                MouseArea
                {
                    id: ma_click
                    anchors.fill: parent
                    onClicked:
                    {
                        webView.e_v=true
                        webView.e_v=true
                        webView.url_d=url
                        webView.empty_page=false
                       loader.push(webView)
                        //console.log(model.)
                    }
                }


            }

            //            model: ListModel
            //            {
            //                id: myListModel1
            //            }
        }
    }

Если сделать так, то делегаты не смещаются к левому краю

highlightRangeMode: ListView.ApplyRange
