font weights don't seem to change

[mzimmers]

Hi all -

This code:

  Column {
      Text {
        font.family: 'roboto'
        font.pixelSize: 24
        font.weight: Font.Normal
        text: "this is an example of roboto with Font.Normal."
      }
      Text {
        font.family: 'roboto'
        font.pixelSize: 24
        font.weight: Font.Medium
        text: "this is an example of roboto with Font.Medium."
      }
      Text {
        font.family: 'roboto'
        font.pixelSize: 24
        font.weight: Font.DemiBold
        text: "this is an example of roboto with Font.DemiBold."
      }
      Text {
        font.family: 'roboto'
        font.pixelSize: 24
        font.weight: Font.Bold
        text: "this is an example of roboto with Font.Bold."
      }
}

Produces this:

Only two weights seem to be visible. Any ideas what's going wrong?

Thanks...

5.14.2, BTW.

@mzimmers Is this something the font has to explicitly support?

@fcarney said in font weights don't seem to change:

@mzimmers Is this something the font has to explicitly support?

Not sure I understand the question -- if the font doesn't support the weighting, how else would it be implemented?

[fcarney]

Seems to be relevant to available fonts and what they support. No idea how this is determined.

Column {
        id: fontcolumn

        anchors.right: parent.right

        //property string fontFam: 'roboto'
        property string fontFam: "Helvetica"

        Text {
            font.family: parent.fontFam
            font.pixelSize: 24
            font.weight: Font.Normal
            text: "this is an example of roboto with Font.Normal."
        }
        Text {
            font.family: parent.fontFam
            font.pixelSize: 24
            font.weight: Font.Medium
            text: "this is an example of roboto with Font.Medium."
        }
        Text {
            font.family: parent.fontFam
            font.pixelSize: 24
            font.weight: Font.DemiBold
            text: "this is an example of roboto with Font.DemiBold."
        }
        Text {
            font.family: parent.fontFam
            font.pixelSize: 24
            font.weight: Font.Bold
            text: "this is an example of roboto with Font.Bold."
        }
    }

    ListView {
        anchors.top: fontcolumn.bottom
        anchors.bottom: parent.bottom
        anchors.right: parent.right

        width: 200

        model: Qt.fontFamilies()

        delegate: Item {
            height: 40;
            width: ListView.view.width
            Text {
                text: modelData;
                MouseArea {
                    anchors.fill: parent
                    onClicked: {
                        fontcolumn.fontFam = modelData
                    }
                }
            }
        }
    }

You will need to re-anchor these Items to see this correctly. It gives you a list of available fonts and selects them when you click on the font name in the list.

@fcarney interesting...on my system, none of the available fonts produced more than 2 distinct weights; some only showed 1. Is this consistent with your findings?

[fcarney]

@mzimmers I think I saw one with 3 diff values. The rest were 2.

[mzimmers]

So, this is an area I know little about; who is to "blame" for the lack of more weight options?

[fcarney]

I suspect if you provided ttf font it might work better. No idea if the system fonts are ttf. Also, adding fonts in Windows is a pain as you have to install them I suppose you could hide a font in a qrc resource. But Windows does weird things with fonts I don't completely understand.

[mzimmers]

I'm running on Linux (actually WSL)...that might be part of the problem, though you said it wasn't working for you, either.

So, do I infer correctly that there's a process for manually adding fonts to Qt?
