推荐答案

你可以使用hasExpired（）函数只在指定数量的毫秒已过期。



请参阅QT文档了解更多详情：

http://qt-project.org/doc/qt-4.8/qelapsedtimer.html#hasExpired [ ^ ]



在那里您可以找到以下示例：

You can use the hasExpired() function to start your processing only after a specified amount of milliseconds has been expired.

Please refer to the QT documentation for more details:
http://qt-project.org/doc/qt-4.8/qelapsedtimer.html#hasExpired[^]

There you will find the following example:

void executeOperationsForTime(int ms)
{
    QElapsedTimer timer;
    timer.start();

    while (!timer.hasExpired(ms))
        slowOperation1();
}
