Qmap Hasnext. QMap features both STL-style iterators and Java-style iterators. It stores (key, value) pairs and provides fast lookup by key. QMap and QHash provide very similar functionality. Detailed Description QMap<Key, T> is one of Qt's generic container classes. Another solution could be just to get an std::map from QMap::toStdMap () and iterate over it using range-for loop. Detailed Description QMap<Key, T> is one of Qt's generic container classes. The STL-style iterators are more low-level and more cumbersome to use; on the other hand, they are slightly faster and, for developers who already know STL, have the advantage of familiarity. QMapIterator<int,QWidget*> i(map); while (i.hasNext()) i.next(); qDebug()<< i.key()<<": "<< i.value(); The next () function returns the next item in the map and advances the iterator.
Qmap Hasnext. It stores (key, value) pairs and provides fast lookup by key. QMap and QHash provide very similar functionality. The "Hash" containers provide faster lookup by using a hash function instead of a binary search on a sorted set. Definition of QMAP in the Definitions.net dictionary. QMap and QHash provide very similar functionality. Qmap Hasnext.

Unlike STL-style iterators, Java-style iterators point between items rather than directly at items.

Qmap Hasnext. The key type of a QMap must provide operator< (). Use the two-argument insert() overload instead. With QHash, the items are arbitrarily ordered. QMultiMap<Key, T> is one of Qt's generic container classes. You can use these algorithms with any container class that provides STL-style iterators, including Qt's QList, QLinkedList, QVector, QMap, and QHash classes.
