    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.

      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 ?

      @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 ?

                                          @TheCipo76
                                          Ok so seems the same as other poster.
                                          Do you also have message in Creator ?
                                          like
                                          Project WARNING: Qt has only been tested with version 10.13 of the platform SDK, you're using 10.14.
