Struct qt_core::QTimerEvent
source · #[repr(C)]pub struct QTimerEvent { /* private fields */ }
Expand description
The QTimerEvent class contains parameters that describe a timer event.
C++ class: QTimerEvent
.
The QTimerEvent class contains parameters that describe a timer event.
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 QTimer class provides a high-level programming interface that uses signals instead of events. It also provides single-shot timers.
The event handler QObject::timerEvent() receives timer events.

sourcepub unsafe fn new(timer_id: c_int) -> CppBox<QTimerEvent>
pub unsafe fn new(timer_id: c_int) -> CppBox<QTimerEvent>
Constructs a timer event object with the timer identifier set to timerId.
Calls C++ function: [constructor] void QTimerEvent::QTimerEvent(int timerId)
.
Constructs a timer event object with the timer identifier set to timerId.

other: impl CastInto<Ref<QTimerEvent>>
) -> CppBox<QTimerEvent>
pub unsafe fn new_copy( other: impl CastInto<Ref<QTimerEvent>> ) -> CppBox<QTimerEvent>

sourcepub unsafe fn timer_id(&self) -> c_int
pub unsafe fn timer_id(&self) -> c_int
Returns the unique timer identifier, which is the same identifier as returned from QObject::startTimer().
Calls C++ function: int QTimerEvent::timerId() const
.
Returns the unique timer identifier, which is the same identifier as returned from QObject::startTimer().
Methods from Deref<Target = QEvent>§
sourcepub unsafe fn accept(&self)
pub unsafe fn accept(&self)
Sets the accept flag of the event object, the equivalent of calling setAccepted(true).
Calls C++ function: void QEvent::accept()
.
Sets the accept flag of the event object, the equivalent of calling setAccepted(true).
Setting the accept parameter indicates that the event receiver wants the event. Unwanted events might be propagated to the parent widget.
See also ignore().
sourcepub unsafe fn copy_from(&self, other: impl CastInto<Ref<QEvent>>) -> Ref<QEvent>
pub unsafe fn copy_from(&self, other: impl CastInto<Ref<QEvent>>) -> Ref<QEvent>
Calls C++ function: QEvent& QEvent::operator=(const QEvent& other)
.
sourcepub unsafe fn ignore(&self)
pub unsafe fn ignore(&self)
Clears the accept flag parameter of the event object, the equivalent of calling setAccepted(false).
Calls C++ function: void QEvent::ignore()
.
Clears the accept flag parameter of the event object, the equivalent of calling setAccepted(false).
Clearing the accept parameter indicates that the event receiver does not want the event. Unwanted events might be propagated to the parent widget.
See also accept().
sourcepub unsafe fn is_accepted(&self) -> bool
pub unsafe fn is_accepted(&self) -> bool
the accept flag of the event object
Calls C++ function: bool QEvent::isAccepted() const
.
the accept flag of the event object
Setting the accept parameter indicates that the event receiver wants the event. Unwanted events might be propagated to the parent widget. By default, isAccepted() is set to true, but don't rely on this as subclasses may choose to clear it in their constructor.
For convenience, the accept flag can also be set with accept(), and cleared with ignore().
Access functions:
bool | isAccepted() const |
void | setAccepted(bool accepted) |
sourcepub unsafe fn set_accepted(&self, accepted: bool)
pub unsafe fn set_accepted(&self, accepted: bool)
the accept flag of the event object
Calls C++ function: void QEvent::setAccepted(bool accepted)
.
the accept flag of the event object
Setting the accept parameter indicates that the event receiver wants the event. Unwanted events might be propagated to the parent widget. By default, isAccepted() is set to true, but don't rely on this as subclasses may choose to clear it in their constructor.
For convenience, the accept flag can also be set with accept(), and cleared with ignore().
Access functions:
bool | isAccepted() const |
void | setAccepted(bool accepted) |
sourcepub unsafe fn spontaneous(&self) -> bool
pub unsafe fn spontaneous(&self) -> bool
Returns true
if the event originated outside the application (a system event); otherwise returns false
.
Calls C++ function: bool QEvent::spontaneous() const
.
Returns true
if the event originated outside the application (a system event); otherwise returns false
.
The return value of this function is not defined for paint events.
