Append a QVector in a QList

I want to append a QVector in a QList but the QVector does not append. The size does not change. I try this with:

y.value(i).append(var);

Variable y is declared as QList<QVector<double>> y;.

QList::value() returns a copy of the element at the given index, not a reference, so modifying it has no effect. Try operator[] instead.
