how to create a sample HTML file using QFIle


  • 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

    @ManiRon said in how to create a sample HTML file using QFIle:

    I am unable to generate file

    In which way? This is not very precise...

    QTextDocument::toHtml

    And ahy do you delete your topics?

  • @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...

    @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);
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.writeEndElement(); //style
htmlWriter.writeEndElement(); //head
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
htmlWriter.writeStartElement(QStringLiteral("p"));
htmlWriter.writeCharacters(QStringLiteral("Lorem ipsum dolor sit amet, consectetur adipiscing elit."));
htmlWriter.writeEndElement(); //p
htmlWriter.writeEndElement(); //body
htmlWriter.writeEndElement(); //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.

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