Thanks for your reply. But this article didn't answer on my questions.

I read sources a little and found that PointerToMembeerFunction is just  
for documentation, and real work is done with QtPrivate::FunctionPointer.

As is clear from name of namespace QtPrivate, this is not good idea to use  
it in my code. And better to not provide such functionality. Am I right?
