推荐答案

不，您不能中止QRunnable任务.

No, you cannot abort a QRunnable task.

在Qt中弄脏线程的唯一方法是通过QThread::terminate()(不鼓励使用).

The only way to dirty-abort a thread in Qt is through QThread::terminate() (which is discouraged).

QThreadPool在后台使用QThread运行QRunnable任务，但是它没有为开发人员提供调用QThread::terminate()的方法.因此，QRunnable无法中止.

QThreadPool uses QThread behind-the-scenes to run QRunnable tasks, but it doesn't provide a way for developers to call QThread::terminate(). Therefore, QRunnable cannot be aborted.

我建议您重新设计应用程序-请参阅Qa中的多线程技术概述使用线程的所有方式，并选择与您的用例匹配的解决方案.

I recommend redesigning your application -- refer to Multithreading Technologies in Qt to get an overview of all the ways you can use threads, and select a solution that matches your use case.
