QList and threads crash

[fred741]

Hi everyone!

I have a QList shared between QRunnable objects. I understand QList isn't thread-safe, but before doing anything with it i lock it using QMutexLocker.
Is it still unsafe to use Qlists in thread with lock mechanism enabled?

Maybe i missed something, so i'm glad for every opinion. :)

As long as you can guarantee that no more than one thread can access the list at the same time you are fine.

I'm using
QMutexLocker locker(&m_mutex);
// m_mutex is the member of the actual object
in the only function which access the list.

I think it should be enough. Do i need take other actions to guarantee safety?

Edit: i've got it. :) Moved the mutex in a scope that every thread see the same, and then applying the lock mechanism. :)
Thanks, for the feedback.
