There're no examples on working with fonts in Graphics View. And when I said there is only one example I talked about charting/CAD/scientific examples.
Everything in QPainter and family regarding fonts applies to GV as well. And besides that fonts are not treated specially in any way, they are just shapes that are rendered to the canvas.

It's obvious for you and - after some time of thinking - for me. But it should be stated in docs.
I don't agree, you can't state everything in the docs, it's simply not possible. You have to assume some level of knowledge of the reader and some level of curiosity and ability of finding information in outside sources.

Does it mean "there is no any handling of resolution mapping and the user must provide his/her own one" or "there is default handling of resolution mapping and in some non-standard cases user can override it" or something else? May be there is an answer in the deep of the docs, but I think it should be here in the same paragraph.
Please read about QPaintDevice and QPaintEngine and everything should become clear.
