    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...

                          @ManiRon This is how a HTML document should look like:

                          <html>
                            <head>
                             HEADER IF NEEDED 
                            </head>
                            <body>
                              YOUR CONTENT HERE
                            </body>
                          </html>

                            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);

                              @ManiRon This is how a HTML document should look like:

                              <html>
                                <head>
                                 HEADER IF NEEDED 
                                </head>
                                <body>
                                  YOUR CONTENT HERE
                                </body>
                              </html>

                              @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.

                                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(); //style

                                    Did you try to compare the HTML you generated with QTextBrowser and the one you are generating now ?
