I can´t found an explanation of the differences of
/reinterpret_cast/ and /dynamic_cast/, because I can´t found
information about /reinterpret_cast/ in Qt Documentation (5.5.0 Qt
version).
You will probably find that Qt doesn't have much to say about them
because they are part of the C++ language.
http://en.cppreference.com/w/cpp/language/dynamic_cast
http://en.cppreference.com/w/cpp/language/reinterpret_cast
...and, since you're looking at casting, you should probably know
about const_cast and static_cast as well:
http://en.cppreference.com/w/cpp/language/const_cast
http://en.cppreference.com/w/cpp/language/static_cast
Also have a look then at the cast operator that Qt _does_ provide:
qobject_cast: http://doc.qt.io/qt-5/qobject.html#qobject_cast
