详细描述

QwtSystemClock provides high resolution clock time functions.

Precision and time intervals are multiples of milliseconds (ms).

( QwtSystemClock is deprecated as QElapsedTimer offers the same precision )

成员函数说明

elapsed()

double QwtSystemClock::elapsed

(

)

const

Get elapsed time in multiples of milliseconds

返回

)

const

Check if the elapsed timer is valid

返回

true if the timer is valid, false otherwise

restart()

double QwtSystemClock::restart

(

)

Restart the elapsed timer

返回
