Detailed Description
Timer events are sent at regular intervals to objects that have started one or more timers. Each timer has a unique identifier. A timer is started with QObject::startTimer().
The QChronoTimer class provides a high-level programming interface that uses signals instead of events.
The event handler QObject::timerEvent() receives timer events.
See also QChronoTimer, QObject::timerEvent(), QObject::startTimer(), and QObject::killTimer().
Member Function Documentation
[explicit, since 6.8] QTimerEvent::QTimerEvent(Qt::TimerId timerId)
Constructs a timer event object with the timer identifier set to timerId.
This function was introduced in Qt 6.8.
[explicit] QTimerEvent::QTimerEvent(int timerId)
Constructs a timer event object with the timer identifier set to timerId.
[protected delete] QTimerEvent::QTimerEvent(QTimerEvent &&)
Move-constructs an instance of QTimerEvent. This function is deleted.
[since 6.8] Qt::TimerId QTimerEvent::id() const
Returns the Qt::TimerId of the timer associated with this event, which is the same identifier returned by QObject::startTimer() cast to Qt::TimerId.
This function was introduced in Qt 6.8.
[noexcept, since 6.9] bool QTimerEvent::matches(const QBasicTimer &timer) const
Returns true if this timer event and timer have the same ID, otherwise returns false.
This function was introduced in Qt 6.9.
int QTimerEvent::timerId() const
Returns the unique timer identifier, which is the same identifier as returned from QObject::startTimer().
[protected delete] QTimerEvent &QTimerEvent::operator=(QTimerEvent &&)
Move-assigns other to this QTimerEvent instance. This function is deleted.
[noexcept protected default] QTimerEvent &QTimerEvent::operator=(const QTimerEvent &other)
Copy-assigns other to this QTimerEvent instance.
