void QVector::pop_front () This function is provided for STL compatibility. It is equivalent to erase(begin()). void QVector::prepend ( const T &value) Insertsvalueat the beginning of the vector. Example: QVector<QString> vector; vector.prepend("one"); vector.prepend("two"); vector....

Maximum number of elements. Complexity Constant. Notes This value typically reflects the theoretical limit on the size of the container, at moststd::numeric_limits<difference_type>::max(). At runtime, the size of the container may be limited to a value smaller thanmax_size()by the amount ...
