No you can't. Use either:

std::vector<QPointF> points;
/*...*/
points.resize(nb);

or

QVector<QPointF> points;
/*...*/
points.resize(nb);

or

QVarLengthArray<QPointF, initial_size> points;
/*...*/
points.resize(nb);

or

QPointF* points = 0;
/*...*/
points = new QPointF[nb];
/*...*/
delete[] points;

or

/* Google "C++ dynamic arrays" */

Hope this helps.
