              QTextDocument qData1(&qHtmlFile);
        qData1.setHtml(qRep);
                qData1.toHtml();

          How should the code above create a file when there is no QFile involved at all? Please be a little bit more careful and think by yourself before posting some useless stuff.

            @Christian-Ehrlicher
            I thought you would understand as i have mentioned the QFile in my first post itself so i thought its fine to just give the main part , is it fine now ?

            QFile qHtmlFile("FilePath");
            QTextDocument qData1(&qHtmlFile);
            qData1.setHtml(qRep);
            qData1.toHtml();

              Please read the docs - I gave you the links so you even don't have to search. This can't work at all...

                    Hi,

                    Use of QFile:

                    • Create QFile variable
                    • Call open
                    • Check that open was successful
                    • Call write
                    • Close file

                    Done

                        @ManiRon Can you please show the code you're using now? And the content of the file you're generating (the text, not pictures)?

                            @ManiRon This is not valid HTML.
                            And by "code" I mean your C++ code to generate the HTML file...

                                        Since you are hard coding stuff anyway, you can use QXmlStreamWriter directly on the QFile device to generate html:

                                        QFile qHtmlFile("myFile.html");
                                        if(qHtmlFile.open(QIODevice::WriteOnly){
                                        QTextStream startDocStream(&qHtmlFile);
                                        startDocStream << QStringLiteral("<!DOCTYPE html>");
                                        QXmlStreamWriter htmlWriter(&qHtmlFile);
                                        htmlWriter.writeStartElement(QStringLiteral("html"));
                                        htmlWriter.writeAttribute(QStringLiteral("xmlns"),QStringLiteral("http://www.w3.org/1999/xhtml"));
                                        htmlWriter.writeAttribute(QStringLiteral("lang"),QStringLiteral("en"));
                                        htmlWriter.writeAttribute(QStringLiteral("xml"),QStringLiteral("lang"),QStringLiteral("en"));
                                        htmlWriter.writeStartElement(QStringLiteral("head"));
                                        htmlWriter.writeStartElement(QStringLiteral("meta"));
                                        htmlWriter.writeAttribute(QStringLiteral("http-equiv"),QStringLiteral("Content-Type"));
                                        htmlWriter.writeAttribute(QStringLiteral("content"),QStringLiteral("text/html; charset=utf-8"));
                                        htmlWriter.writeEndElement(); //meta
                                        htmlWriter.writeStartElement(QStringLiteral("title"));
                                        htmlWriter.writeCharacters(QStringLiteral("Test Page"));
                                        htmlWriter.writeEndElement(); //title
                                        htmlWriter.writeStartElement(QStringLiteral("style"));
                                        htmlWriter.writeCharacters(QStringLiteral("h1, h2, h3, h4 { color: rgb(83,129,53) } h1 { text-align: center; }"));

                                        htmlWriter.writeStartElement(QStringLiteral("body"));
                                        htmlWriter.writeStartElement(QStringLiteral("h1"));
                                        htmlWriter.writeCharacters(QStringLiteral("Test Page"));
                                        htmlWriter.writeEndElement(); //h1
                                        htmlWriter.writeStartElement(QStringLiteral("h2"));
                                        htmlWriter.writeCharacters(QStringLiteral("Lorem"));
                                        htmlWriter.writeEndElement(); //h2

                                          @jsulm I have not defined the html tag but still it was generating the html file correctly but when i removed the QTextbrowser , still it was generating correctly but the internal borders of the table is only the major missing.
