Oh, I've just incorrectly expressed what I meant. I've seen these demos and talked about flowcharting demo ("Diagram Scene"). All others have nothing (almost nothing - there are some interesting ideas I've found useful for me) to do with flowcharting and CADs - there are demos on working with pictures, animation and other such things. 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.
Hmm... isn't it obvious? The scaling is done using a matrix, so it's not hard to calculate that given negative values this will make the coordinates "flipped" around the respective axis.
It's obvious for you and - after some time of thinking - for me. But it should be stated in docs. It's not so difficult to describe and without it I can not treat docs to be complete - too many different "small" aspects are supposed to be obvious and thus are not described. It's bad. IMHO.
Really? What's this then?
Mmm, somehow I've missed this though I've searched for this info in Assistant. May be because I haven't used physicalDpi methods and haven't paid enough attention to their description.
And after reading this I do not see what the following means: "the corresponding QPaintEngine must handle the resolution mapping". 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.
It's all there, you just didn't look good enough Did you open Assistant and type in "Graphics View" (or even "Graphics View example") in the search tab? I guess you didn't... You could have also chosen "Qt examples" from the main documentation page and then click on "Graphics View" category.
Yes, surely, I've read it and seen these demos and examples. I've already told that I'm playing with Graphics View for about two months, but I could easily miss something and even more easily could misunderstand some points - English is not my native language and there are no any translations of Graphics View docs into Russian (and there are no Russian books on this technology) .
