      @Christian-Ehrlicher this is my code

            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.

          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...

                                      startDocStream << QStringLiteral("<!DOCTYPE html>");
                                      QXmlStreamWriter htmlWriter(&qHtmlFile);
                                      htmlWriter.writeStartElement(QStringLiteral("html"));
                                      htmlWriter.writeAttribute(QStringLiteral("xmlns"),QStringLiteral("http://www.w3.org/1999/xhtml"));

                                        @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.
