[Qt-interest] ugly QGraphicsTexItem when it is zoomed

[changwon lee]

  Hello

I have struggled to solve it. my conclusion is as follows.
there are two option.
1. avoid to use small pointsize (< 1) by controlling scene coordinate. 
(setUseDesignMetric is not helpful in very small pointsize)
2. use QPainterpath

the extent of my graphicsitem is about 6. and I have to add textItem 
which has pointsize of 0.1~0.8.
in this case when I use QGraphicTextItem and zoom, it looks ugly and in 
edit mode, textcursor is too thick and boundRect is too big.
I abandoned interactive editing of QGraphicsTextItem.
instead I draw text by QPainterPath and to edit text I have used some 
text edit dialog by double-clicking item.

but if I magnify model coordinate by some factor, then maybe 
QGraphicsTextItem can be used because of larger pointsize.
but I want to use model coordinate as it is.

regards
