Qt containers or STL containers?

[sparticus_37]

which should i use and why should i use them when building a multithreaded QT app, the QT container classes or those provided by the STL?

Qt Concurrent supports several STL-compatible container and iterator types, but works best with Qt containers that have random-access iterators, such as QList or QVector...

The answer is: depends on many things (like how do you use threads, what modification you do to data...)

Neither STL nor Qt containers are thread-safe. Both STL and Qt containers are reentrant.
