I first thought that replacing the foreach loop would probably not affect the performance much, but when iterating the keys of a QMap, rather than, e.g., the elements of a QVector, it saves the creation of the temporary list returned by itemStates.keys() (I guess that this was also the explanation that Thiago gave - maybe it was in a private discussion, Mark? I could not see any comment from Thiago here).
