Issue with Qt thread affinity and moveToThread

Question

I\'m trying to use threads in Qt to delegate some work to a thread, but I can\'t get it to work. I have a class inheriting QMainWindow that have a member object that launch

Answer 1

I think the problem is with the initialization of m_poller, which according to the error message seems to be assigned to a different (third) thread from the one that is executing your code snippet.

Also, if this code is executed multiple times, it may work the first time but then fail on subsequent times as m_poller no longer belongs to the executing thread, but rather m_pollThread.
