    I have been creating the HTML file using the QTextbrowser , But now i want to create it with out using the QTextbrowser. How can this be done , will there be any samples available?

    I used some thing like this:

    QFile qHtmlFile("File Path");
    QTextDocument qData1(&qHtmlFile);
    qData1.SetHtml(QString);

      QTextBrowser is using a QTextDocument internally which is responsible for the html in/output

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

                  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...
