But I still do not know how to create an object like QHash<int,QString>.I checked the file qhash.sip and find that 
 QHash<TYPE1, TYPE2> is implemented as a Python dictionary.So is it possible to convert a dict object into a QHash<TYPE1,TYPE2> object?Because I can not use a dict object with QDataStream's operator "<<" directly.
Thanks a lot.
