Beginner problems with QML and glyphs

? Offline

Hi,

I'm new to QT. At the moment I'm playing around for testing with qml and i encountered a strange problem:
I started to use the material fonts as icons.

For this i added the Font in cpp:
QFontDatabase::addApplicationFont(":/Ressources/MaterialSymbolsOutlined.ttf");

then i try to use it in QML:
ToolButton {
font.family: "MaterialSymbolsOutlined"
font.pixelSize: 24
text: "\ue900"
}

here i get a totaly wrong icon displayed, while "\ue8ff" as example works just well.

Do you have got any idea what i'm doing wrong here?

Thanks

I would recommend using icons as .svg instead of iconfonts
Buttons support icon themes : https://doc.qt.io/qt-6/qtquickcontrols-icons.html .
Write an icon.theme file pointing to a folder with your icons then you could do the following in your code:

ToolButton {
    icon.name: "zoom_out"
}

Thank you,
I will take look at it.
