pub struct SignalEvent { /* private fields */ }
Expand description

The SignalEvent class represents a Qt signal event.

C++ class: QStateMachine::SignalEvent.

C++ documentation:

The SignalEvent class represents a Qt signal event.

A signal event is generated by a QStateMachine in response to a Qt signal. The QSignalTransition class provides a transition associated with a signal event. QStateMachine::SignalEvent is part of The State Machine Framework.

The sender() function returns the object that generated the signal. The signalIndex() function returns the index of the signal. The arguments() function returns the arguments of the signal.

Calls C++ function: [constructor] void QStateMachine::SignalEvent::SignalEvent(QObject* sender, int signalIndex, const QList<QVariant>& arguments).

source

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

The SignalEvent class represents a Qt signal event.

Calls C++ function: [constructor] void QStateMachine::SignalEvent::SignalEvent(const QStateMachine::SignalEvent& other).

C++ documentation:

A signal event is generated by a QStateMachine in response to a Qt signal. The QSignalTransition class provides a transition associated with a signal event. QStateMachine::SignalEvent is part of The State Machine Framework.

The sender() function returns the object that generated the signal. The signalIndex() function returns the index of the signal. The arguments() function returns the arguments of the signal.

source

pub unsafe fn sender(&self) -> QPtr<QObject>

Returns the object that emitted the signal.

Calls C++ function: QObject* QStateMachine::SignalEvent::sender() const.

C++ documentation:

Returns the object that emitted the signal.

See also QObject::sender().

source

pub unsafe fn signal_index(&self) -> c_int

Returns the index of the signal.

Calls C++ function: int QStateMachine::SignalEvent::signalIndex() const.

C++ documentation:

Returns the index of the signal.

See also QMetaObject::indexOfSignal() and QMetaObject::method().

Methods from Deref<Target = QEvent>§

source

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().

C++ documentation:

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().

source

pub unsafe fn copy_from(&self, other: impl CastInto<Ref<QEvent>>) -> Ref<QEvent>

Calls C++ function: QEvent& QEvent::operator=(const QEvent& other).

source

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().

C++ documentation:

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().

source

pub unsafe fn is_accepted(&self) -> bool

the accept flag of the event object

Calls C++ function: bool QEvent::isAccepted() const.

C++ documentation:

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)
source

pub unsafe fn set_accepted(&self, accepted: bool)

the accept flag of the event object

Calls C++ function: void QEvent::setAccepted(bool accepted).

C++ documentation:

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)
source

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.

C++ documentation:

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.

source

pub unsafe fn type_(&self) -> Type

Returns the event type.

Calls C++ function: QEvent::Type QEvent::type() const.

C++ documentation:

Returns the event type.
