Loading

void AsyncTestTask::startAsyncTask() {
    _timer.start();
    QThread::sleep(2);
        _timer.stop();
        emit finished(id());
}

代码阻塞在AsyncTaskQueue::finishTask 函数。可能是QMutexLocker造成的阻塞。

AsyncTestTask::timeout() 内的_timer.stop(); emit finished(id());却可以正常执行。不会阻塞进程。

感觉很奇怪，不太好理解。
不知道作者还来不来看不看这里了，如果方便请帮忙解答一下。谢谢！
