请看一下qt文档中的timers.html
我这里有一份译文
http://www.qiliang.net/qt/timers.html
其中一段文字为
There is practically no upper limit for the interval value (more than one year is possible). The accuracy depends on the underlying operating system. Windows 95/98 has 55 millisecond (18.2 times per second) accuracy; other systems that we have tested (UNIX X11 and Windows NT) can handle 1 millisecond intervals.
事实上,对于间隔值是没有上限的(超过一年也是可能的)。精确性依赖于位于下面的操作系统。Windows 95/98的精确度为55毫秒(每秒18.2次),其它我们已经测试过的操作系统(UNIX X11、Windows NT和OS/2)都可以处理1毫秒的间隔。 |
