ClockType
This enum contains the different clock types that QElapsedTimer may use.
Definition: qelapsedtimer.h:56
#define QT_END_NAMESPACE
This macro expands to.
Definition: qglobal.h:90
qint64 msecsTo(const QElapsedTimer &other) const
Returns the number of milliseconds between this QElapsedTimer and other.
friend bool Q_CORE_EXPORT operator<(const QElapsedTimer &v1, const QElapsedTimer &v2)
Returns true if v1 was started before v2, false otherwise.
The QElapsedTimer class provides a fast way to calculate elapsed times.
Definition: qelapsedtimer.h:53
static bool isMonotonic()
Returns true if this is a monotonic clock, false otherwise.
qint64 elapsed() const
Returns the number of milliseconds since this QElapsedTimer was last started.

This macro expands to.
Definition: qglobal.h:89
qint64 restart()
Restarts the timer and returns the time elapsed since the previous start.
