I'm not sure what kind of example is necessary.  How about if you ask
specific questions about the arguments of that function which you
don't understand clearly how to use?

No, it returns the size of _text_ when displayed in a window.

I didn't mean text-width, I meant the use of string-width: it should
be replaced by a call to window-text-pixel-size.
