maybe I should use font.pointSize instead of font.pixelSize ??
thanks for help

Better to use the pointSize. Also you can calculate 46/800 only once and use it everywhere. It may little bit performance impact with propertybindings every time.

thank you for reply
I try to use pointSize, but found in log
@
QFont::setPointSizeF: Point size <= 0 (0.000000), must be greater than 0

switching to pointSize do not help, the same problem
