Oh, now I understand: It fixes the issue that the styleName was prefilled with the stylename of the default font and fromString might not reset it. IMO that's a feature though and is the expected behaviour. For instance, if we change the default window title to be bold, users with "windowTitle=Comic Sans" will also have a bold title. qtbase's src/gui/text/qfont.cpp says: setFamily(l[0].toString()); if (count > 1 && l[1].toDouble() > 0.0) setPointSizeF(l[1].toDouble()); if (count == 9) { setStyleHint((StyleHint) l[2].toInt()); setWeight(qMax(qMin(99, l[3].toInt()), 0)); setItalic(l[4].toInt()); setUnderline(l[5].toInt()); setStrikeOut(l[6].toInt()); setFixedPitch(l[7].toInt()); } else if (count >= 10) { if (l[2].toInt() > 0) setPixelSize(l[2].toInt()); setStyleHint((StyleHint) l[3].toInt()); setWeight(qMax(qMin(99, l[4].toInt()), 0)); setStyle((QFont::Style)l[5].toInt()); setUnderline(l[6].toInt()); setStrikeOut(l[7].toInt()); setFixedPitch(l[8].toInt()); if (count == 11) d->request.styleName = l[10].toString(); else d->request.styleName.clear(); } So just specifying exactly 10 parameters as part of the config key should have the exact same effect.
