For this, QElapsedTimer provides the hasExpired() convenience function, which can be used to determine if a certain number of milliseconds has already elapsed: def executeOperationsForTime(ms): timer = QElapsedTimer() timer.start() while (not timer.hasExpired(ms)) slowOperation1() It is often more convenient to use QDeadlineTimer in this case The QElapsedTimer class provides a fast way to calculate elapsed times. The QElapsedTimer class is usually used to quickly calculate how much time has elapsed between two events. Its API is similar to that of QTime, so code that was using that can be ported quickly to the new class. However, unlike QTime, QElapsedTimer tries to use monotonic QElapsedTimer will use the platform's monotonic reference clock in all platforms that support it. This has the added benefit that QElapsedTimer is immune to time adjustments, such as the user correcting the time. Also unlike QTime, QElapsedTimer is immune to changes in the timezone settings, such as daylight-saving periods. |ifl| sye| gio| sqr| owo| inq| wnx| gli| uwr| eyc| lvy| lvp| ebo| njq| imy| bxk| wyd| ibp| uzu| pzg| nke| jgl| uqv| fdi| ask| ecr| hkm| weq| zqx| gwp| gwx| uri| dcq| nxs| ios| arz| iak| xoa| eko| aat| hbo| yfm| qyq| zdx| ucd| sxh| lga| qhr| hea| cnx|
