I'm attempting to generate a PDF file from `QTextDocument`, which is working just fine. The issue comes when I want to use a custom font for just a specific `<p></p>` object. I tried using the standard means of `QFontDatabase::addApplicationFont()` which successfully gets the font loaded into the application, but for some reason it writes all of the `QString` based variables that are added to `messageBody` in this font instead of that specified by `QTextFocument.setDefaultFont()`, or even a manually via `style={font-family:}`.

Am I doing this wrong, or overlooking something here, or is this some kind of bug?



Qt Code: 
  1. int main(int argc, char *argv[])
  2.     {
  3.        QApplication a(argc,argv);
  4.  
  5.        // With this added, all hell breaks loose
  6.        QFontDatabase::addApplicationFont(":/Barcode.ttf");
  7.  
  8.        QString messageBody;
  9.        QString serialNumber = "ABC123";
  10.        messageBody += "<p style='font-size: large;'><b>Serial Number:</b> " + serialNumber + "</p>";
  11.        messageBody += "<p style='font-size: large; font-family=\"Console\"'><b>Serial Number:</b> " + serialNumber + "</p>";
  12.  
  13.  
  14.        QTextDocument document;
  15.        document.setHtml(messageBody);
  16.  
  17.        QFont myfont("Console", 8, QFont::Normal);
  18.        document.setDefaultFont(myfont);
  19.  
  20.        QPrinter printer(QPrinter::PrinterResolution);
  21.        printer.setOutputFormat(QPrinter::PdfFormat);
  22.        printer.setOutputFileName("test.pdf");
  23.  
  24.        document.print(&printer);
  25.  
  26.         return 0;
  27.     }
To copy to clipboard, switch view to plain text mode 


In either case I would get the output PDF like so:

I can't wrap my head around why/how it would differentiate the base QString (messageBody) from those that are concatenated into it (serialNumber)?
