    Description

      In my QML application I use external font. The font contains several styles, each style in a separate file. All the files are in a resource.

       

      QList<QString> fonts = { "Montserrat-Black.otf", "Montserrat-BlackItalic.otf", "Montserrat-Bold.otf", "Montserrat-BoldItalic.otf", "Montserrat-Medium.otf", "Montserrat-MediumItalic.otf", "Montserrat-Regular.otf", "Montserrat-Italic.otf", "Montserrat-Light.otf", "Montserrat-LightItalic.otf", "Montserrat-Thin.otf", "Montserrat-ThinItalic.otf" };  

foreach(const QString &font, fonts) { 
    if(QFontDatabase::addApplicationFont(":/fonts/" + font) == -1) 
        qDebug() << "Error loading font: " + font; 
}

      Font usage:

      Button { 
    text: qsTr("Sign In") 
    font.weight: Font.Medium
    font.family: "Montserrat" 
}
Button { 
    text: qsTr("Sign In")
    font.pixelSize: 18
    font.weight: Font.Normal
    font.family: "Montserrat" 
 }

       

       

      The result:

      QML just ignores Font.Medium and display it as Font.Normal.

      That how it looks in Sketch:

      All the fonts are installed in Windows.

      If I try to change the font weight in Designer, only Normal and Bold make sense. All other weights are displayed as Normal.

       The Montserrat font could be found [here|http://example.com]
