project fonts not being used

[mzimmers]

Hi all -

I'm trying to use some custom fonts for my UI. Here are the fonts in project view:

and my code for enabling a couple of them:

    FontLoader {
        id: rubikSemiBold
        source: "qrc:/fonts/Rubik/static/Rubik-SemiBold.ttf"
        onStatusChanged: if (rubikSemiBold.status == FontLoader.Ready) console.log('Loaded')
    }
    FontLoader {
        id: rubikItalic
        source: "qrc:/fonts/Rubik/static/Rubik-Italic.ttf"
    }
...
    NavSymbol {
        id: homeIcon
        iconFile: "qrc:/icons/Home.png"
        labelText: "Home"
        fontFam: rubikItalic.name
    }
...
// my Navsymbol.qml file
RowLayout {
    id: navSymbol
    property string iconFile: "qrc:/icons/blank.png"
    property string labelText: "to be replaced"
    property string fontFam: "unknown"
    
      Image {
        source: navSymbol.iconFile
    }
    Label {
        text: navSymbol.labelText
        font {
            family: fontFam
            pixelSize: navSymbol.fontSize
        }
    }

I'm not getting a runtime error, but the fonts aren't being used. Can someone see what I'm doing wrong?

Thanks...

are the font files added to your qml.qrc file?

@Markkyboy I don't have a qml.qrc file. The file the fonts are in is "resources.qrc:"

<RCC>
    <qresource prefix="/">
        <file>fonts/Rubik/static/Rubik-Black.ttf</file>
        <file>fonts/Rubik/static/Rubik-BlackItalic.ttf</file>
        <file>fonts/Rubik/static/Rubik-Bold.ttf</file>
        <file>fonts/Rubik/static/Rubik-BoldItalic.ttf</file>
        <file>fonts/Rubik/static/Rubik-ExtraBold.ttf</file>
        <file>fonts/Rubik/static/Rubik-ExtraBoldItalic.ttf</file>
        <file>fonts/Rubik/static/Rubik-Italic.ttf</file>
        <file>fonts/Rubik/static/Rubik-Light.ttf</file>
        <file>fonts/Rubik/static/Rubik-LightItalic.ttf</file>
        <file>fonts/Rubik/static/Rubik-Medium.ttf</file>
        <file>fonts/Rubik/static/Rubik-MediumItalic.ttf</file>
        <file>fonts/Rubik/static/Rubik-Regular.ttf</file>
        <file>fonts/Rubik/static/Rubik-SemiBold.ttf</file>
        <file>fonts/Rubik/static/Rubik-SemiBoldItalic.ttf</file>
    </qresource>
</RCC>

which is in CMakeLists.txt:

   qt_add_executable(
   appnga_demo
   main.cpp
   icons.qrc
   resources.qrc
   ...

The FontLoader seems to be finding the fonts (I tried substituting a nonsense name, and got an error, but I get no error with the "good" names). Somehow, they're just not being used.
