# const_iterator Class

class QList::const_iterator

Provides an STL-style const iterator for QList and QStack. More...

## Detailed Description

QList provides both STL-style iterators and Java-style iterators.

Warning: Iterators on implicitly shared containers do not work exactly like STL-iterators. You should avoid copying a container while iterators are active on that container. For more information, read Implicit sharing iterator problem.

Warning: Iterators are invalidated when QList is modified. Consider that all iterators are invalidated by default. Exceptions to this rule are explicitly documented.
