    Ok, im asking as it seems just as odd as
    https://forum.qt.io/topic/98726/qtextedit-make-text-bold
    which is also mac.

    Could you also try with
    http://doc.qt.io/qt-5/qtwidgets-richtext-textedit-example.html
    and use Verdana and see if that sample can make it bold ?

      Hi,
      i'm creating a PDF with QPrinter and QPainter..

          qreal top=15, left=10, right=10, bottom=15;
          QPrinter printer(QPrinter::HighResolution);
          printer.setOrientation(QPrinter::Portrait);
          printer.setOutputFormat(QPrinter::PdfFormat);
          printer.setPaperSize(QPrinter::A4);
          printer.setPageMargins(left, top, right, bottom, QPrinter::Millimeter);
          Oggi = QDate::currentDate();
          QString DtOggi = Oggi.toString("dd-MM-yyyy");
          ui->lineEdit_DtRNC->setText(DtOggi);
          QString NomeFile = "RNC " + ui->comboBox_Fornitore->currentText() + " del " + DtOggi;
          QString fileName = QFileDialog::getSaveFileName(nullptr,"file", NomeFile, "pdf (*.pdf)");
          printer.setOutputFileName(fileName);
          QPainter painter;
          painter.begin(&printer);
          QPen paintpen (Qt::black);
          painter.setPen(paintpen);
          painter.setFont(QFont("Verdana", 20, QFont::ExtraBold));
          painter.drawText(2000, 50, "BOLD TEXT");                                //BOLD TEXT
          painter.setFont(QFont("Verdana", 12, QFont::Normal));
          painter.drawText(2000, 250, "NORMAL TEXT");                      // NORMAL TEXT
      

      but when i open the PDF file all the text was normal.. Bold was not applied

      Anyone know why??
      Thanks in advance.

      Hmm, is it simple coincidence that the on-going https://forum.qt.io/topic/98726/qtextedit-make-text-bold seems unresolved and is reporting a similar problem with no-bold, though admittedly in a QTextEdit. Any connection...??

        Yes, same code works on other platforms.
        And if sample dont work either, its an OS/Qt thing. (it seems as no Qt app can make font bold then)
        But yes could also be totally a coincidence but i have no macOS to test on.

          @mrjj Yes, i've tried using Verdana and works correctly

          I've modified my code like this:

          QFont bold("Verdana", 20);
          bold.setBold(true);
          painter.setFont(bold);
          painter.drawText(2000, 50, "BOLD TEXT");
          

          but no bold text..

            Hi
            Tried your code.
            The QPainter was not active. ( logged errors to Creator)
            QPainter::begin(): Returned false
            QPainter::begin(): Returned false
            QPainter::setPen: Painter not active
            QPainter::setFont: Painter not active
            QPainter::setFont: Painter not active
            so font was never set, i think.
            if i do

            ....
                  QPainter painter(&printer); // give it directly
                   //painter.begin(&printer);
                   QPen paintpen (Qt::black);
                   painter.setPen(paintpen);
            ...
            

            i get
            alt text

              @mrjj i've made the changes you told me up but
              nothing changed
              no way to have bold text

              with qdebug i've checked font selection
              this is debug message

              Painter isActive: true
              Painter Font: QFont( "Verdana,20,-1,5,75,0,0,0,0,0" ) //Bold
              Painter Font: QFont( "Verdana,12,-1,5,50,0,0,0,0,0" )
              Painter Font: QFont( "Verdana,10,-1,5,50,0,0,0,0,0" )
              Painter Font: QFont( "Verdana,12,-1,5,75,0,0,0,0,0" ) //Bold
              Painter Font: QFont( "Verdana,11,-1,5,75,0,0,0,0,0" ) //Bold
              Painter Font: QFont( "Verdana,11,-1,5,50,0,0,0,0,0" )
              Painter Font: QFont( "Verdana,11,-1,5,75,0,0,0,0,0" ) //Bold
              Painter Font: QFont( "Verdana,11,-1,5,50,0,0,0,0,0" )

              75 is Bold ( as i've setted by code..)

              but was not applied

              Probably was a bug

                        Sample is like 98% your code. just removed the Date stuff.
                        Even to Image is your code, just to a pixmap.
                        Rest of it, is the same. So something must have went wrong
                        altering the code, or maybe it didnt use new code or something.

                            Good hunting. Now we know it will work so
                            its just to compare sample to actual code and see what could be difference.

                                    Aha, and did you try the
                                    http://doc.qt.io/qt-5/qtwidgets-richtext-textedit-example.html
                                    example on mac too ?
                                    We have other poster that has Bold issue on macOs.
                                    https://forum.qt.io/topic/98726/qtextedit-make-text-bold

                                    so its kinda important to know if RichText sample do not go bold for you either as it then
                                    smells like a Qt thing /Xcode / macOS version thing.

                                        @mrjj Yes, i've tried using Verdana and works correctly

                                        I've modified my code like this:

                                        QFont bold("Verdana", 20);
                                        bold.setBold(true);
                                        painter.setFont(bold);
                                        painter.drawText(2000, 50, "BOLD TEXT");
                                        

                                        but no bold text..

                                          Hi
                                          (only talking macOs)
                                          So Rich Text can do bold but your code does not ?
                                          So unlike other poster - its sort of mixed.
                                          Very odd.
                                          Also if not even my sample with image give Bold text then
                                          something is not workings it should.
                                          I wonder if the font itself could be the issue.
                                          did you try with other fonts in the code ?
