Yes, you are right of course. I could have checked it online, for a lack 
of having the Qt sources at hand.

 I only found it for QLatinString and QByteArray:
 (Where is the declaration for QByteArray?)
 ...
 inlineboolQByteArray::operator==(constQStrings)const
 {returnqStringComparisonHelper(s,constData());}
 ...

 Please can somebody help me?

It's in qstring.cpp:

bool QString::operator==(const QString other) const
{
 if (d-size != other.d-size)
 return false;

 return qMemEquals(d-data, other.d-data, d-size);
}
