Thank you for replying but none of these answers are usefull:

to JPN : the Trolltech doc for qSort() only treat single variable QList. Operators are presented for performing special sortings.

to yunpeng880 : my problem is not how to store structured datas in a QList class, but how to sort a field from a structured data once it has been stored in a QList.

In any case, thanks for your replies.
