      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..
