示例1: updateAdjustedSize

    const float specifiedSize = fontDescription.specifiedSize();
    if (!fontDescription.hasSizeAdjust() || !specifiedSize)

    // We need to create a temporal Font to get xHeight of a primary font.
    // The aspect value is based on the xHeight of the font for the computed font size,
    // so we need to reset the adjustedSize to computedSize. See FontDescription::effectiveFontSize.
    fontDescription.setAdjustedSize(fontDescription.computedSize());

    Font font(fontDescription);
    font.update(fontSelector);
