Issue with QVBoxLayout while adding a QWebEngineView and QQuickView

[ejos]

I am trying to create e-reader with pages displayed by QWebEngineView and toolbar written in QML and displayed using QQuickView.

Main.cpp

include <QVBoxLayout>
#include <QDesktopWidget>
#include <toolbar.h>
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QDesktopWidget dw;
    WebEngineView *weView = new WebEngineView();
    weView->setGeometry(0,55,dw.width(),(dw.height()));
    QQuickView view;
    view.setSource(QUrl("qrc:/ReaderToolBar.qml"));
    view.setGeometry(0,0,dw.width(),50);
    view.setMinimumHeight(50);
    view.setMaximumHeight(50);
    QVBoxLayout *lay = new QVBoxLayout();
    lay->addWidget(QWidget::createWindowContainer(&view));
    lay->addWidget(weView);
    QWidget *wid = new QWidget();
    wid->setLayout(lay);
    wid->resize(dw.width(),dw.height());
    wid->show();
    return app.exec();
}

WebEngineView.qml

#include "WebEngineView.h"
WebEngineView::WebEngineView()
{
this->setUrl(QUrl("http://www.google.co.in"));
}

ReaderToolBar.qml

import QtQuick 2.0

Rectangle {
    id: tbrect
    width: 1200
    height: 50
    color: "transparent"
    visible: true

    MouseArea {
        anchors.fill: parent
        hoverEnabled: true
    }

    function showicons()
    {     
        libicon.visible = true
        tocicon.visible = true
   }
Image {
        id: libicon
        x: 30
        smooth: true
        height: 36
        width: 36
        anchors.bottom: parent.bottom
        anchors.bottomMargin: 8
        source: "qrc:/images/library.png"
        visible: true

        MouseArea {
            id: libiconma
            anchors.fill: parent
            onClicked: {
                //rw.showlibrary()
            }
        }
    }

    Image {
        id: tocicon
        x: 90
        smooth: true
        height: 50
        width: 50
        anchors.bottom: parent.bottom
        //anchors.bottomMargin: 2
        source: "qrc:/images/toc.png"
        visible: true

        MouseArea {
            anchors.fill: parent
            onClicked: {
                //rw.showtocinwebview();         
            }
        }
Component.onCompleted: showicons()
}

Here the WebEngineView alone is displayed and the tool bar is not getting displayed.
Let me know what I am missing so that tool bar is superimposed on the webenginview
