QEventLoopLocker 操作特定對象，如 QCoreApplication 實例， QEventLoop 實例或 QThread 實例。
例如，這使采用事件循環運行一批作業，並在完成最後作業後退齣相應事件循環成為可能。這的施行是通過保持 QEventLoopLocker 由各作業實例。
變體操作 QCoreApplication 使它在關閉最後 GUI 窗口之後異步完成運行作業成為可能。例如：這對運行把數據上傳到網絡的作業是很有用的。

[noexcept]
QEventLoopLocker::
QEventLoopLocker
()
創建事件鎖定器操作 QCoreApplication .
The application will attempt to quit when there are no more QEventLoopLockers operating on it, as long as
QCoreApplication::isQuitLockEnabled
() 是
true
.
Note that attempting a quit may not necessarily result in the application quitting, if there for example are open windows, or the QEvent::Quit 事件被忽略。
另請參閱 QCoreApplication::quit () 和 QCoreApplication::isQuitLockEnabled ().
[explicit noexcept]
QEventLoopLocker::
QEventLoopLocker
(
QEventLoop
*
loop
)
創建事件鎖定器操作 loop .
這尤其 QEventLoop 將離開，當沒有更多 QEventLoopLockers 操作它時。
另請參閱 QEventLoop::quit ().
[explicit noexcept]
QEventLoopLocker::
QEventLoopLocker
(
QThread
*
thread
)
創建事件鎖定器操作 thread .
這尤其 QThread 將離開，當沒有更多 QEventLoopLockers 操作它時。
另請參閱 QThread::quit ().
[noexcept, since 6.7]
QEventLoopLocker::
QEventLoopLocker
(
QEventLoopLocker
&&
other
)
Move-constructs an event-loop locker from other . other will have a no-op destructor, while responsibility for preventing the QEventLoop / QThread / QCoreApplication from quitting is transferred to the new object.
該函數在 Qt 6.7 引入。
[noexcept]
QEventLoopLocker::
~QEventLoopLocker
()
銷毀此事件循環鎖定器對象
[noexcept, since 6.7]
void
QEventLoopLocker::
swap
(
QEventLoopLocker
&
other
)
Swaps the object and the state of this QEventLoopLocker with other 。此操作很快且從不失敗。
該函數在 Qt 6.7 引入。
[noexcept, since 6.7]
QEventLoopLocker
&QEventLoopLocker::
operator=
(
QEventLoopLocker
&&
other
)
Move-assigns this event-loop locker from other . other will have a no-op destructor, while responsibility for preventing the QEventLoop / QThread / QCoreApplication from quitting is transferred to this object.
該函數在 Qt 6.7 引入。
[noexcept, since 6.7]
void
swap
(
QEventLoopLocker
&
lhs
,
QEventLoopLocker
&
rhs
)
Swaps the object and the state of lhs with rhs 。此操作很快且從不失敗。
