The answer to your question was already given (QVector), but I'd like to point
out one discrepancy in your email.
Your subject talks about QList<float>, but the body of your email talks about a
linked list.
QList is not a linked list -- QLinkedList is a linked list and std::list is a
linked list.
QList is technically a pointer array, with a special optimisation to store the
type in the pointer value if it fits and is movable.
