You mean adding the font name into the CSS code? This seems to be the only way \
indeed. However, watch out for the infinite loop:
setFont calls FontChange calls setStyleSheet calls QStyleSheetStyle::repolish(w) \
calls updateWidgets calls style->polish(w) calls QStyleSheetStyle::setPalette() calls \
w->setFont, GOTO 10. Somehow you'll have to distinguish "setFont done by the user" \
from "setFont done by the style". No idea other than a nasty boolean-based \
re-entrancy protection...
