Qt QVector - can I change by reference a value in an element?
===

I have a 

    QVector<structure> m_vector;

the structure has many fields, some of them fixed-dimension and some of them other dynamic QVectors..

I'm wondering if I can do this:

    m_vector[4].another_vector[9].another_vector[2].field_in_the_structure = 2;

will the change be valid to the entire m_vector?
