In C++ there is a convention that ugly things should look ugly in code. Removing element from the middle or beginning of contiguous container is ugly thing. If you need such operation in your code, you should consider using linked list instead, which allows to remove element with one method call (std::list::remove or std::list::remove_if) -- Regards, Konstantin _______________________________________________ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
