Re: Difference between QString::ref and QString::operator[]

Hi,

Mmmh... This looks disturbing. The following code shows s2 is always
shorter than s1 (exactly one character):
#include <QString>
#include <QtDebug>
int main() {
QString s1, s2;
for(int i = 0; i < 5; ++i) {
s1[i] = 'x';
s2.ref(i) = 'x';
qDebug() << s1.size() << "-" << s2.size();
}
}
I would suggest sending a bug report to Trolltech:

Maybe I'm missing something, but in any case this could indeed be
documented.
