計時器事件按定期間隔被發送給已啓動一個或多個計時器的對象。每個計時器擁有唯一標識符。啓動計時器采用 QObject::startTimer ().
The QChronoTimer class provides a high-level programming interface that uses signals instead of events.
事件處理程序 QObject::timerEvent () 接收計時器事件。
另請參閱 QChronoTimer , QObject::timerEvent (), QObject::startTimer (),和 QObject::killTimer ().
[explicit, since 6.8]
QTimerEvent::
QTimerEvent
(
Qt::TimerId
timerId
)
構造計時器事件對象,采用將計時器標識符設為 timerId .
該函數在 Qt 6.8 引入。
[explicit]
QTimerEvent::
QTimerEvent
(
int
timerId
)
構造計時器事件對象,采用將計時器標識符設為 timerId .
[since 6.8]
Qt::TimerId
QTimerEvent::
id
() const
返迴 Qt::TimerId of the timer associated with this event, which is the same identifier returned by QObject::startTimer () cast to Qt::TimerId .
該函數在 Qt 6.8 引入。
[noexcept, since 6.9]
bool
QTimerEvent::
匹配
(const
QBasicTimer
&
timer
) const
返迴
true
if this timer event and
timer
have the same ID, otherwise returns
false
.
該函數在 Qt 6.9 引入。
返迴唯一計時器標識符,其是相同標識符作為返迴來自 QObject::startTimer ().
