Hello,
it is possible to compute the exact width of a string using QFontMetrics.width(QString) but surprisingly it is nt possible to get its height as well since only QFontMetrics.height() is available, which returns some maximum height of a string using a given font. Is it possible to compute the real height of a given string, ie some QFontMetrics.height(QString) functionality?
why would u need that..QFontMetrics.height() would return the same thing as QFontMetrics.height(QString) would, if there was any...
In your opinion, is the height of any string the same? For instance is the height of "oo" the same as the height of "lp"?Quote:

Just try to answer to mu previous question and you should be able to understand that you are wrong.Quote:

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.Quote:

Height is basically for the whole string, so its logical for it to be same.
However, font metrics dont consist of just height, there are also ascent and descent.(QFontMetrics::ascent,QFontMetrics::descent).
Have a look at them too.
Also there was som example related to fonts on Qt Labs.. Font Anatomy. I think on SVN, under graphics directory. Have a look at it too, it might help :)
