    Description

      I import different types of the font "Helvetica Neue":

      // load fonts from resources
int fontId0 = QFontDatabase::addApplicationFont(":/font/HelveticaNeue-Regular.ttf");	
int fontId1 = QFontDatabase::addApplicationFont(":/font/HelveticaNeue-CondensedBlack.ttf");	
int fontId2 = QFontDatabase::addApplicationFont(":/font/HelveticaNeue-Light.ttf");	
int fontId3 = QFontDatabase::addApplicationFont(":/font/HelveticaNeue-Thin.ttf");	
int fontId4 = QFontDatabase::addApplicationFont(":/font/HelveticaNeue-UltraLight.ttf");

      In order to use e.g. "Helvetica Neue UltraLight" under macOS I have to set the font.styleName property to "UltraLight":

      font.styleName: "UltraLight"

      The same code doesn't work on Windows 10. 

      To use the same font on Windows 10 the font.weight property must be set to "Font.ExtraLight" (this in return is not working on macOS):

      font.weight: Font.ExtraLight
