Public Member Functions inherited from QEvent
	QEvent (Type type)
	Constructs an event object of type type.
virtual	~QEvent ()
	Destroys the event.
Type	type () const
	Returns the event type.
bool	spontaneous () const
	Returns true if the event originated outside the application (a system event); otherwise returns false.
virtual void	setAccepted (bool accepted)
bool	isAccepted () const
void	accept ()
	Sets the accept flag of the event object, the equivalent of calling setAccepted(true).
void	ignore ()
	Clears the accept flag parameter of the event object, the equivalent of calling setAccepted(false).
bool	isInputEvent () const noexcept
bool	isPointerEvent () const noexcept
bool	isSinglePointEvent () const noexcept
virtual QEvent *	clone () const
	Creates and returns an identical copy of this event.

Constructor & Destructor Documentation

QMetaCallEvent() [1/4]

QMetaCallEvent::QMetaCallEvent	(	ushort	method_offset,
		ushort	method_relative,
		QObjectPrivate::StaticMetaCallFunction	callFunction,
		const QObject *	sender,
		int	signalId,
		void **	args,
		QSemaphore *	semaphore
	)

Used for blocking queued connections, just passes args through without allocating any memory.

Definition at line 535 of file qobject.cpp.

References args().

Here is the call graph for this function:

QMetaCallEvent() [2/4]

QMetaCallEvent::QMetaCallEvent	(	QtPrivate::QSlotObjectBase *	slotO,
		const QObject *	sender,
		int	signalId,
		void **	args,
		QSemaphore *	semaphore
	)

Used for blocking queued connections, just passes args through without allocating any memory.

Here is the call graph for this function:

QMetaCallEvent() [3/4]

QMetaCallEvent::QMetaCallEvent	(	ushort	method_offset,
		ushort	method_relative,
		QObjectPrivate::StaticMetaCallFunction	callFunction,
		const QObject *	sender,
		int	signalId,
		int	nargs
	)

Allocates memory for nargs; code creating an event needs to initialize the void* and int arrays by accessing args() and types(), respectively.

Definition at line 568 of file qobject.cpp.

QMetaCallEvent() [4/4]

QMetaCallEvent::QMetaCallEvent	(	QtPrivate::QSlotObjectBase *	slotO,
		const QObject *	sender,
		int	signalId,
		int	nargs
	)

Allocates memory for nargs; code creating an event needs to initialize the void* and int arrays by accessing args() and types(), respectively.
