Как в QML сделать растягивающийся интерфейс

qml

Добрый день.
Как в QML сделать растягивающийся интерфейс?
В Qt дизайнере можно регулировать отношение виджитов на экране через соотношение сгрупированных лэйаутов на экране. Хорошо это описанно тут
Но как это можно реализовать в QML?
Вот пример страницы, на которой тринируюсь

import QtQuick 2.4
import QtQuick.Controls 2.4

Item {
    id: page2element
    width: 400
    height: 600
    property alias page2Button0: page2Button0
    property alias page2Button1: page2Button1
    property alias page2Button2: page2Button2
    property alias page2Button3: page2Button3
    property alias page2ButtonMenu: page2ButtonMenu
    property alias page2Label1: page2Label1
    property alias page2Label2: page2Label2



    Button {
        id: page2ButtonMenu
        x: 150
        y: 493
        text: qsTr("МЕНЮ")
        anchors.horizontalCenter: parent.horizontalCenter
        font.pointSize: 18
    }

    Label {
        id: page2labe0
        x: 57
        y: 49
        width: 286
        height: 33
        text: qsTr("Выберете красный цвет")
        anchors.horizontalCenterOffset: 0
        anchors.horizontalCenter: parent.horizontalCenter
        font.family: "Verdana"
        horizontalAlignment: Text.AlignHCenter
        font.pixelSize: 22
        font.weight: Font.Thin
    }

у тебя все элементы имеют точку привязки (х,у), используй соотношение елементов друг к другу

    А как это сделать. Нужно узнавать ширину и высоту дисплея?

        Спасибо. Статью читал. К сожалению этот вариант страницы не запускается в скомпилированной программе. Но по такому принципу сделал нижиприведенный код. Но при этом не получилось достичь масштабируемости. Помогите пожалуйста решить это:

            Кажется я понял, нужно похоже так делать, тогда пропорции сохраняются

            spacing: /*50*/0.1 * page2element.width

              QML достаточно гибок, чтоб достичь желаемого разными способами, достаточно включить фантазию

                Но есть ли возможности в дизайнере это сделать, без лишнего кода?

                  А Ваш код ошибок не выдовал, но программа просто не открывала эту страницу
