[Qt-interest] Re : Re : Follow-up "QHash::const_iterator not reentrant?"

[BOUCARD Olivier]

Because to make myself clear.

I have also a case, where calling end() and begin() with const_iterator on the same shared object with a different QHash, which actually works!
The only difference its that I cannot set this second QHash from the exterior, onlyconstructors can.
