Добрый день!

Для этого можно использовать QML тип Flickable, а также типы ScrollBar

Вот пример

main.qml

import QtQuick 2.11
import QtQuick.Window 2.11
import QtQuick.Controls 2.4

Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")

    Flickable {
        width: 200
        height: 200
        clip: true
        contentWidth: clientLoader.width;
        contentHeight: clientLoader.height
        ScrollBar.vertical: ScrollBar { }
        ScrollBar.horizontal: ScrollBar { }

        Loader {
                id: clientLoader
                clip: true
                source: Qt.resolvedUrl("qrc:/MainArea.qml")
            }
    }
}

MainArea.qml

        Rectangle {

        Rectangle {

                }
                GradientStop {
                    position: 1.00
                    color: "transparent"
                }
            }
        }

Спасибо! Работает.
