    Hi I think it maybe be related to the rc file somehow.
    I added a qrc to a project and then directly added the ttf file.
    and then in mainwindow constructor

    int loadedFontID = QFontDatabase::addApplicationFont ( ":/Triforce.ttf" );
    QFont Triforce("Triforce", 24, QFont::Normal);
    ui->label->setFont(Triforce);
    

    and it just worked. ?! So I think you are really close to nailing it :)

    That doesn't work either....
    where did you put the ttf file? In the same folder as the cpp files?

      Been wondering, are you using linux? windows? osx? If linux you need to have fontconfig installed (according to documentation)

      I'm sort of running out of suggestions, hopefully someone senior appears as like you I've recently started on this journey with C++/Qt .

      I guess my last suggestion would be instead of calling addapplicationfont call

       QFile file(":/Triforce.ttf"); // the one that returned true
      qDebug () << QFontDatabase::addApplicationFontFromData(file.readAll());
      
      

      As for the implications of loading it like thatI wouldn't know. Best of luck.

        I'm using Windows 10...
        Calling addApplicationFontFromData gives me this in the application output:
        QIODevice::read (QFile, ":\Triforce.ttf"): device not open
        QFSFileEngine::open: No file name specified
        -1

          Yes ttf in same folder as cpp files. Then right clicked qrc and "add existing file" .

              Could you try this mini test ?
              https://www.dropbox.com/s/h75uamsxonvvczx/myhappyfont.zip?dl=0

              Works here on win 7.

                  Hehe I buy your guts theory.. :)

                  Ok, so my best bet is something with the rc file.

                  could you try with the one from the test ?
                  remember to put .ttf in same folder

                  Just let Creator compile it.

                    Exactly what mrjj says, QtCreator handles resources just fine there's no need to compile it manually. You can add your qrc to your .pro file and avoid all those headaches. Moreover, you can edit/add files and prefixes as you see fit through QtCreator.

                    I tested the app since I got curious. http://i.imgur.com/mhtj26i.png

                    One thing to keep in mind. If you add text under Rich Text, QT will respect the HTML generated and it will ignore any attempts to manipulate it. Remove the HTML in the label if there's any, else it will never render with the selected font.

                      @David.G I did everything qrc related with the Qt Creator...
                      The only thing I compiled myself was the rcc file since that was mentioned in the wiki. Seeing as how mrjj's app works fine without it I've deleted the rcc though.

                      @mrjj I tried it with your qrc as well (even though I knew that they were exactly the same) and I still get the same error

                      Update: heh....I got it to work...seems to be a bad idea to do the font stuff before the setupUi line....seems obvious enough once you see it. I've already tried it in my VM and yes, it really works now! Thanks for all your help!!
