• QMutex“A mutex must be unlocked in the same thread that locked it”解决(在run里创建对象是不二法宝)


    多线程时出现如下警告信息:

    A mutex must be unlocked in the same thread that locked it;

    原因可能有二:

    1.创建QMutex不在当前线程;

    2.QWaitCondition::wait 调用前没有调用QMutex::lock;

     

    解决方法:

    1.在run函数中创建QMutex;

     

    ...

    m_pMutex = new QMutex();

    ...

     

    2.wait前调用lock:

     

    QMutexLocker locker(m_pMutex);

     m_waitCond.wait(m_pMutex);
