WebView with QQuickWidget and QQuikView

Hi,

I am trying to view an html file(google maps) with WebView on QQuickWidget. The html loads without an error(console log says that) ;but nothing is shown on QQuickWidget, just a white screen..

When I replace QQuickWidget with QQuickView everything works fine. But since there are some issues with QQuickView on mobile platforms, I dont want to use it.

I have attached a minimal runnable code.

Any idea?

Thanks in advance..

Code looks like that:

Code:

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
 
#ifdef WITH_QUICKWIDGET
    view = new QQuickWidget();
    ui->verticalLayout->addWidget(view);
#else
    view = new QQuickView();
    QWidget* container = QWidget::createWindowContainer(view);
    ui->verticalLayout->addWidget(container);
#endif
    view->setSource(QUrl::fromLocalFile(QLatin1String(":/web/weblink.qml")));
    mapApiKey = QString::fromLatin1("AIzaSyAOeIxkqfAs9HQrz_PY7QPz7ZzKiML7hDE");
    m_webDir = QDir::homePath()+QString::fromLatin1("/") ;
    loadHtml();
}
 
MainWindow::~MainWindow()
{
    delete ui;
}
 
void MainWindow::loadHtml()
{
 
    QString htmlData = loadFileData(QString::fromLatin1(":/web/map.html"));
    htmlData.replace(QLatin1String("$$API_KEY"),mapApiKey);
    htmlData.replace(QLatin1String("$$PORT"),QLatin1String("1000"));
    htmlData.replace(QLatin1String("$$WEB_DIR"),QUrl::fromLocalFile(m_webDir).toString());
 
    QString htmlfname = QString::fromLatin1("map_%1.html").arg(QDateTime::currentMSecsSinceEpoch());
    htmlData.replace(QLatin1String("$$MAP_HTML"),htmlfname);
 
    m_filePath = saveFile( htmlData, htmlfname);
 
    if(!QFileInfo::exists(m_webDir + QString::fromLatin1("jquery.min.js")))
        QFile::copy(QLatin1String(":/web/jquery.min.js") , m_webDir+QLatin1String("jquery.min.js"));
 
    if(!QFileInfo::exists(m_webDir + QString::fromLatin1("label.js")))
        QFile::copy(QLatin1String(":/web/label.js") , m_webDir+QLatin1String("label.js"));
 
    QObject *object = view->rootObject();
    QQmlProperty::write(object, QString::fromLatin1("url"), QUrl::fromLocalFile(m_filePath).toString());
}
 
QString MainWindow::loadFileData(QString path)
{
    QString data;
    QFile readfile(path);
    if(readfile.open(QIODevice::ReadOnly)){
        QTextStream txt(&readfile);
        data = txt.readAll();
        readfile.close();
    }
    return data;
}
 
QString MainWindow::saveFile(QString htmldata, QString fname)
{
    QString mpath= m_webDir+fname;
    QFile writefile(mpath);
    if(writefile.open(QIODevice::WriteOnly)){
        QTextStream txt(&writefile);
        txt << htmldata;
        writefile.close();
    }
    return mpath;
}
