Have a look a QString doc.

Are these ok?

int toInt ( bool * ok = 0, int base = 10 ) const
std::string toStdString () const

Will my answer be faster to read then the function documentation?
I mean really, no disrespect, but what do you expect with such questions?

Do they work? If so, yes, otherwise, No :)
