Need your opinion on resource of QTextDocument

[CharlieG]

Hello,

I want use resource and addResource of QTextDocument to load a html model and stylesheet.

Here, my currently code :

    QTextDocument *tdContent = new QTextDocument(this);
    tdContent->setPageSize(contentSize);


    QFile styleFile(m_modelStyle);
    QString style;
    if (styleFile.open(QFile::ReadOnly | QFile::Text))
    {
        QTextStream in(&styleFile);
        style = in.readAll();
    }

    QFile model(m_model);
    if (model.open(QFile::ReadOnly | QFile::Text))
    {
/// what is the best way for you ? Use QTextStream or directly use resource of QTextDocument ?
        /*
        QTextStream in(&model);
        m_totalHtml = in.readAll();
        */
        m_totalHtml = tdContent->resource(QTextDocument::HtmlResource, QUrl(m_model)).toString();


        tdContent->addResource(QTextDocument::StyleSheetResource, QUrl( "style.css" ), style);
        for (const auto i : m_dataModel)
        {
            QStringList tuple = i.toStringList();
            m_totalHtml.replace("$"+tuple[0]+"$", tuple[1]);
        }
    }
    else {
        addContent();

    }

    tdContent->setHtml(m_totalHtml);
    //tdContent->addResource(QTextDocument::HtmlResource, QUrl(m_model), m_totalHtml);

If I comment tdContent->setHtml(m_totalHtml);and I uncomment the last line, it doesn't work.
Do I make a mistake using addResource ?

Thank you for help.

Charlie.
