    Did you check the returned id from addApplicationFont ?

      @SGaist More or less, what I did to test that the font is working is this:

      int id = QFontDatabase::addApplicationFont( "/usr/share/fonts/truetype/Open_Sans/OpenSans-Regular.ttf");
      QString family = QFontDatabase::applicationFontFamilies(id).at(0);
      QFont monospace(family);
      qApp->setFont(monospace);
      

      But it doesn't work.... No idea what can be happening

          @SGaist I'm trying to show the value of the "id" variable through QDebug and the Application output but it's not showing.

            Use the debugger then or a dummy widget.

              @SGaist Ok, I wasn't pressing the "Debug" button haha, anyways I've found that the "id" value is 0.

                        @mrjj Yes, What I did was

                        QFontDatabase::addApplicationFont("/usr/share/fonts/truetype/Open_Sans/OpenSans-Regular.ttf");
                        

                        and then select "Open Sans" on the QtDesigner
