void TestThread::timeoutSlot() { m_pTimer->stop(); qDebug() << QString::fromLocal8Bit("当前线程id:") << QThread::currentThread(); } 上面的代码将出现以下错误: QObject::killTimer: Timers cannot be stopped from another thread 综上,子类化线程类的方法可行,但是不太好。 3.正确用法二 无...
System.Threading.Timer: executes a single callback method on a thread pool thread at regular intervals. The callback method is defined when the timer is instantiated and cannot be changed. Like theSystem.Timers.Timerclass, this class is intended for use as a server-based or service component ...
Because this class supports access from different threads, it is conceivable that the Stop method may be called on a thread other than the thread that is used for the Elapsed event. This could potentially result in the Elapsed event firing even after the Stop method has been called. You can...
