WebJan 5, 2014 · QVector<double> * vect = new QVector<double>; vect->resize(100); void QVector::resize(int size) Sets the size of the vector to size. If size is greater than the current size, elements are added to the end; the new elements are initialized with a default-constructed value. If size is less than the current size, elements are removed from the end.

WebThe Container Classes. Qt provides the following sequential containers: QList, QStack, and QQueue. For most applications, QList is the best type to use. It provides very fast appends. If you really need a linked-list, use std::list. QStack and QQueue are convenience classes that provide LIFO and FIFO semantics.

WebSep 30, 2020 · QVector and QList are unified. Previously, Qt featured very different implementations for these two containers: QVector being a natural and straightforward array-like container and QList being rather special in its implementation to nicely accommodate types defined and used by Qt itself.
