How to return the keys of a map in a vector

[Lykurg]

Just as a side node: With toVector() you won't save so much, because it also expands to a loop. It's only a little bit more sophisticated:

Q_OUTOFLINE_TEMPLATE QVector<T> QList<T>::toVector() const
{
    QVector<T> result(size());
    for (int i = 0; i < size(); ++i)
        result[i] = at(i);
    return result;
}

Q_OUTOFLINE_TEMPLATE QVector<T> QList<T>::toVector() const
{
    QVector<T> result(size());
    for (int i = 0; i < size(); ++i)
        result[i] = at(i);
    return result;
}
