WebThis is by far the most commonly used container class. It stores a list of values of a given type (T) that can be accessed by index. Internally, the QList is implemented using an array, ensuring that index-based access is very fast.Items can be added at either end of the list using QList::append () and QList::prepend (), or they can be inserted ...
