QML FontLoader: Cannot load font

[CodeBroker]

Hello

I can't for the life of me, get the FontLoader to work. I have tried following the documentation, but it still doesn't work.
I am making an app for Android.

The .ttf is in the same folder as the project files (./Lato-Regular.ttf).
FontLoader is a component of Window (root). Button is a component of a Grid, that is a component of Window.

I have also tried adding the .ttf to a .qrc file, but I get the same error, even when using "qrc:/x"

FontLoader {
            id: customfont
            source: "Lato-Regular.ttf"
    }

Button {
            id: requestItemButton
            width: 250
            height: 150
            antialiasing: true
            Material.roundedScale: Material.NotRounded

            contentItem: Text {

                text: "Request Items"
                font: customfont.font
                color: "#CE0F69"
                //#800080
                //"#920092"
                //font.pixelSize: 20
                antialiasing: true
                horizontalAlignment: Text.AlignHCenter
                verticalAlignment: Text.AlignVCenter
            }
        }

Hi and welcome to devnet,

Your executable is not in the same folder as your sources so using a relative path won't work.
As for using qrc: did you create a proper Qt resource to make use of it ?

@SGaist Hello and thanks :). I used Qt Creator to create a resource file, and added the font file to it via the GUI. i.e "qrc:/Fonts/myfont.ttf"

@CodeBroker
Could you show your actual FontLoader code when using a resource, please?

FontLoader {
            id: customfont
            source: ":/Lato-Regular.ttf"
    }

@CodeBroker
So (not my area, never used resources) clearly :/... is not the way to do it. qrc:/... looks better. You use qrc:/Lato-Regular.ttf here, but earlier you said you were going to use/it has been added as qrc:/Fonts/..., so perhaps you need that here? What is the actual path to the embedded font in the resources? From C++ code you can use QFile::exists("...") to check whether a resource file exists. I'm not sure whether that expects :/... or qrc:/... syntax.

@JonB I have tried multiple paths, none of them work. I use qrc:/ when using icons, and that works fine; but I have added them in the cmakelists.txt. I find no resources that tells me to put any font path in cmakelists.txt, and neither do I know how to add them.

[JonB]

@CodeBroker
That I don't know, as I don't use resources or cmake. But if cmakelists.txt does include something for icon resources but nothing for font resources that does not sound right, maybe the runtime failures are because the font is not actually embedded.

@JonB That's what I suspect, but if that were the case, I would expect to find a lot more people sharing my issue, as the documentation doesn't mention it.
