Question

I have 2 datas which type is QMap:

1.QMap novel; QString tempChapter; QString tempStory;

2.QMap combo; int tempInd; QString tempChap;

Answer 1

Basically, you will have to think of a format to store your data in yourself. I would suggest to read something about serialization. Read this for some general information about serialization in C++.

Answer 2

All of the basic collections in qt are supported by QDataStream check for support in the QMap docs, as you are only storing other basic qt types and ints you should be ok
