获取在Qt的时间 [英] Get elapsed time in Qt

问题描述

我在Qt中寻找等效的 GetTickCount（）

I'm looking for the equivalent in Qt to GetTickCount()

测量一段代码运行所花费的时间：

Something that will allow me to measure the time it takes for a segment of code to run as in:

uint start = GetTickCount();
// do something..
uint timeItTook = GetTickCount() - start;

有什么建议吗？

推荐答案

QTime ？根据您的平台，它应该有1毫秒的精度。代码看起来像这样：

How about QTime? Depending on your platform it should have 1 millisecond accuracy. Code would look something like this:

QTime myTimer;
myTimer.start();
// do something..
int nMilliseconds = myTimer.elapsed();
