[Qt-qml] Why can't I stylesheet a font?

[Jason H]

Actually I like Gregory's better still. While I'd likely put the "style sheet" 
stuff in a separate file, your implementation implies that I'd have to have a 
file for every item of every style. HTML CSS's files can be one per site, and 
that's a huge feature.

And the fact that I can specify font and color (which isn't a part of font!?)  
at the same time is really handy.


Still, good to know...

Something also like that, but that you can do in QML today, is:

MyText.qml
Text{
    font.face: "Arial"
    font.pointSize: 20
    color: "red"
}
main.qml

MyText{
    text: "Hello"
}

This approach has the advantage of being linked to the type. This means that 
you only use the properties relevant for that type. Also the precedence is 
clear, so if you want to set a different color but keep the other properties, 
that's easy and should be unambiguous.

The downside of this approach is that you need an extra file, but presumably if 
these properties are worthwhile separating out you may want to use them in 
multiple files anyways.
