QFontMetrics would give you the size of the title, assuming that you
know the font that is used (which on X11 is not really possible). And
then you still don't know how big the various buttons are (system menu,
minimize, maximize, close etc), so the using QFontMetrics to calculate
the size of the title bar contents give you an educated guess, at best.

I don't say it's useless in general, but I think it's not useful enough
to make its way into a library with general-purpose solutions. I'll
bring it up with our Qt Solutions team though.
