QML WebEngineView: how to prohibit user interactions?

VTiTux

Hello,
I would like to show a web page to my application, but my user shall not modify anything.
For mouse events, I stack an invisible item that caught all events, but for the keyboard, I cannot disable the focus of my WebEngineView:

import QtQuick 2.0
import QtQuick.Window 2.0
import QtWebEngine 1.3

Window {
    width: 1024
    height: 750
    visible: true


    Item{
        anchors.fill: parent
        focus: false
        Keys.enabled: false

        Keys.onPressed: {
            console.log("key locked")
            event.accepted = true
        }

        WebEngineView{
            anchors.fill: parent
            url: "https://forum.qt.io"
            z: 0
            focus: false
            Keys.enabled: false

            Item{
                id: lockScreen1
                anchors.fill: parent
                z: 1
                enabled: true
                visible: true
                focus: true
                Keys.enabled: true

                Keys.onPressed: {
                    console.log("key locked")
                    event.accepted = true
                }
            }
        }

        Item{
            id: lockScreen2
            anchors.fill: parent
            z: 1
            enabled: true
            visible: true
            focus: true
            Keys.enabled: true

            Keys.onPressed: {
                console.log("key locked")
                event.accepted = true
            }

            MouseArea{
                anchors.fill: parent
                onWheel: {}
            }
            MultiPointTouchArea{
                anchors.fill: parent
            }
            PinchArea{
                anchors.fill: parent
            }
        }

    }
}

How to do that?

I added

            onFocusChanged: {
                    lockScreen2.forceActiveFocus()
            }

into my WebEngineView.
This works, except for the first 'tab' pressed, which scroll my view to top.

Another idea?
