I haven't looked at this code (and thus am not entirely sure what you are commenting on), but just a quick comment - QSet is a hash-based container.  i.e., it provides amortized constant look up (and cannot be ordered).  I assume the purpose of using such a container is for efficient look up, in which case the Qt implementation would generally perform better than its STL counterpart, which I believe is tree-based.
