While using QtCreator, it gave me a handy tooltip:

QVector<int> v;
v.remove( -> tooltip [2 of 2| void remove(int i, int *n*)]

However the documentation says: "void remove(int i, int count)". (Due to the brevity of i and n, I wanted to make sure I was putting the right values in the right places)
I had expected the tooltip to be [2 of 2| void remove(int i, int *count*)]

I posted this to the QtC mailing list and was advised to post about it here. Not sure if there is an automated way to check that the API names match the documentation names. FWIW, I prefer count because that is more specific than n.

It's a small detail, but rather important, I think.
