QDirIterator could be rewritten either as an input or a forward Standard Library iterator. It wouldn't be a bad idea because its implementation is broken: while you're trying to get the information about the current item, it's stat()ing the next. It's also hard to guess which element you're getting and whether you're accidentally skipping the first entry, or missing the last one. All of which are caused by the fact that it *is* a Java-style iterator. -- Thiago Macieira - thiago.macieira (AT) intel.com Cloud Software Architect - Intel DCAI Cloud Engineering
