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...
QObject::killTimer: Timers cannot be stopped from another thread QObject::startTimer: Timers can only be used with threads started with QThread 由于某种原因,我在pycharm中运行测试程序时没有得到这些消息,但这表明计时器没有从正确的main thread调用。我知道PyQT5中有一些内置方法可以为计时器添加快捷方式。
今更ですが、QThread::startedシグナルの存在意義を理解できた気がします。 Worker::Worker(QObject*parent):QObject(nullptr),_thread(newQThread(parent)),_timer(nullptr){_timer=newQTimer(this);connect(_timer,&QTimer::timeout,this,&Worker::onTimeout);_timer->setSingleShot(true);moveToThread(...
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 ...
Depending on the selected mode of operation, the counter is cleared, incremented, or decremented at each timer clock (clkTn). The clock clkTn can be generated from an external or internal clock source, as selected by the Clock Select bits in the Timer/Counter Control Register B (TC...

Operating systems do great work, but sometimes they need a little bit of help to know when to switch from one task to another. Thankfully, hardware is there to help! Today we are going to take a look at how operating systems schedule reminders for themse
To start an event loop from a non-GUI thread, useQThread::exec(). Qt uses the timer'sthread affinityto determine which thread will emit thetimeout() signal. Because of this, you must start and stop the timer in its thread; it is not possible to start a timer from another thread. ...
