        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.

                                  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.
