There is a simple printf idiom which replaces all of this, e.g.:

litem->settext(0,QString().sprintf("%*d", digits, x);

So that you don't need to build up the format string dynamically.

If you want to do this in Qt style, Qt provides a QTextOStream:

Which acts like a C++ ostream, with the usual (and quite different from
printf) formatting operators.
