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 ... WebThis is guaranteed by Associative container requirements in the C++ standard. E.g. see 23.2.4/10 in C++11: The fundamental property of iterators of associative containers is that they iterate through the containers in the non-descending order of keys where non-descending is defined by the comparison that was used to construct them. thoya thoya
