MFC中定时器OnTimer函数 在每个此时间间隔后触发定时处理程序,实现周期性的自动操作。例如,我们可以在数据采集系统中,为定时器设置定时采集时间间隔为1个小时,那么每隔1个小时系统就会采集一次数据,这样就可以在无人操作的情况下准确...使用定时器的对话框类,在属性窗口选择消息,在下面的消息函数中选中WM_TIMER,后面...

Once scheduled on a run loop, the timer fires at the specified interval until it is invalidated. A nonrepeating timer invalidates itself immediately after it fires. However, for a repeating timer, you must invalidate the timer object yourself by calling itsinvalidate()method. Calling this method...

RunLoop可以说是每个线程都有的一个对象,是用来接受事件和分配任务的loop。永远不要手动创建一个runloop,它是跟随着每个线程的。一个RunLoop接收两种source的事件:input source和timer source。同时必须知道的是,input source,runloop是异步交付的,而timer source是同步交付的。每个runloop都有一个RunLoop Modes,代表它以...

1.获取到一个expiry已经过期的链表,首次向下执行时`ranAtLeastOneList`为false,则将其置为true,然后执行`listOnTimeout()`这个方法;2.然后继续取堆顶的链表,如果也过期了,再次执行时,会先执行`runNextTicks()`,再执行`listOnTimeout()`。 我们按照逻辑顺序,先来看看listOnTimeout( )这个方法,它有近100行...
