QFontMetrics.height()

[Caius Aérobus]

no point arguing about it , i believe i m right here , if you were right, Qt would have included such a function..

but Qt developpers might not thinking about specific cases, such as when all characters are in CAPS, and in this case no one goes below the baseline, which leads to a wrong measure. So since they have developped a way to evaluate string width, it was probably not that difficult to provide a similar functionaliy for height.
