how to properly pause and resume QThread execution?



  • how to make threads to be in sleep or running state?


  • Moderators

    QSemaphore barrier;
    
    // In thread supposed to sleep:
    barrier.acquire();
    
    // In thread that wakes the sleeping thread:
    barrier.release();
    

    Be careful though, because you're asking for trouble putting a thread to sleep for too long (it won't be able to process events) and also try not to deadlock it. :)
