best way to delete QVector<QVector3D>

What is the best way to delete

QVector<QVector3D> vertices

QVector<QVector3D> vertices

To copy to clipboard, switch view to plain text mode 

I already cleared it. Now for deleting it, I tried to use qDeleteAll() function, but
it asks for begin and end iterators. I do not know how to iterate through all vectors and call qDeleteAll(). Nor do I know if that is really necessary.
On the other hand, vertices.reserve(0) also does not delete the whole thing. (I don't think so)

what's your idea?
