A few ideas (in case you have not tried them already): If the functions is called several times in a row with same info (same font, maybe even same string!) you could cache data. Instead of building a QString, you could call yourself width(QChar) on each character, unless there is some kerning going on. Do you know whether a lot of calls are for a single character? In this case it would be worth specializing this case. I'm sure you thought about that already, but it never hurts to propose. What do you think is hurting qt more than xforms? The unicode conversion? JMarc
