Qt printing using html and QTextDocument

kuntio · wrote on 24 Jan 2022, 18:06

I fight with printing pdf from QTextDocument object with html format. I generate QString formatted code of html page and it works fine. To test it i make using QFile a html file which have to be printed and it look greats.
But pdf file looks completly different and i don't know why.

Code:

    QString html = getHtmlPrintString(FVToPrint, currentCustomer);
    QTextDocument document;
    document.setHtml(html);

    QFile qHtmlFile("D:\\Qt\\projects\\FVGeneratorV2\\fv\\"+QString::fromStdString(FVToPrint.getFVId()) +".html");
    if(qHtmlFile.open(QIODevice::WriteOnly))
    {
        qHtmlFile.write(html.toUtf8());
        qHtmlFile.close();
    }

    QPrinter printer(QPrinter::PrinterResolution);
    printer.setOutputFormat(QPrinter::PdfFormat);
    printer.setPageSize(QPageSize::A4);
    QString fvname = "D:\\Qt\\projects\\FVGeneratorV2\\fv\\" + QString::fromStdString(FVToPrint.getFVId()) + ".pdf";
    printer.setOutputFileName(fvname);
    printer.setPageMargins(QMarginsF(15, 15, 15, 15));

    document.print(&printer);

Html file code:

<!DOCTYPE html>

<html>



<head>

  <meta http-equiv='Content-Type' content='text/html; charset=utf-8'>

  <style type='text/css'>

    table,

    tr,

    td {

      border: 1px solid black;

      border-collapse: collapse;

    }

    

    td {

      padding: 1%;

    }

    

    html,

    body {

      th: 100%;

      height: 100%;

      margin: 0;

      padding: 0;

Hi and welcome to devnet,

Do you mean that if you have that document printed on paper it works correctly but not as a PDF ?

In any case, don't forget that QTextDocument does not support the full range of HTML capabilities.

kuntio · S SGaist 24 Jan 2022, 19:33

@SGaist I mean i save file with QString html formatted text and when i open it in chrome it look as i want. Now i change div's to table because only table have border and float property in CSS Rich Text, but i still don't look as a html in web browser.

This remark I wrote is really important:

@SGaist said in Qt printing using html and QTextDocument:

In any case, don't forget that QTextDocument does not support the full range of HTML capabilities.

kuntio · S SGaist 24 Jan 2022, 20:29

@SGaist i know it and i think that now i have everything that QTextDocument support, but it still look like width property didn't work correctly. Check it how it looks now because i edit the post. Only clear property is not supporting and i don't know what i should use instead of them. I tried float:none but it didn't work as i want. I edit post check how it looks now

IIRC, there should be no px after border.

kuntio · S SGaist 24 Jan 2022, 20:54

syntax from documentation for border <width>px <border-style> <border-color>
That's mean it should be px after border.
