How to make Fullscreen for QtQuick 2.10 Control Application

[NTMS]

Hi,
I am using import QtQuick 2.10. I need to make fullscreen mode. I try to add
flags: Qt.Window | Qt.FramelessWindowHint
and didn't work for me?

import QtQuick 2.10
import QtQuick.Controls 2.3

ApplicationWindow {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")
    //flags: Qt.Window | Qt.FramelessWindowHint  // This didn't work.


    Text {
        id: mainPage
        text: qsTr("Main Page")
        font.pixelSize: Qt.application.font.pixelSize * 1
    }

    SwipeView {
        id: swipeView
        anchors.fill: parent
        currentIndex: 1 //tabBar.currentIndex

        Page1Form {
        }

        Page2Form {
        }

        Page3Form {

        }
    }

    footer: TabBar {
        id: tabBar
        currentIndex: swipeView.currentIndex

        TabButton {
            text: qsTr("Left Page")
            font.pixelSize: Qt.application.font.pixelSize * 0.7

            MouseArea {
                anchors.fill: parent
                onPressed: {
                    currentIndex: 0
                }
            }
        }

        TabButton {
            text: qsTr("Mid Page")
            font.pixelSize: Qt.application.font.pixelSize * 0.7

            MouseArea {
                anchors.fill: parent
                onPressed: {
                    currentIndex: 1
                }
            }
        }

        TabButton {
            text: qsTr("Right Page")
            font.pixelSize: Qt.application.font.pixelSize * 0.7

            MouseArea {
                anchors.fill: parent
                onPressed: {
                    currentIndex: 2
                }
            }
        }
    }
}

@Devopia53 thank you very much. I forgot to import QtQuick.Window 2.3. Its working now.

Here is the code:

import QtQuick 2.10
import QtQuick.Controls 2.3
import QtQuick.Window 2.3

ApplicationWindow {
visible: true
width: 640
height: 480
title: qsTr("Hello World")
flags: Qt.Window | Qt.FramelessWindowHint
visibility: Window.FullScreen
