◆ addConnection()

void QObjectPrivate::addConnection	(	int	signal,
		Connection *	c )

inline

Add the connection c to the list of connections of the sender's object for the specified signal

The signalSlotLock() of the sender and receiver must be locked while calling this function

Will also add the connection in the sender's list of the receiver.

		int	signal_index,
		const QObject *	receiver,
		QtPrivate::QSlotObjectBase *	slotObjRaw,
		Qt::ConnectionType	type )

static

Used by QML to connect a signal by index to a slot implemented in JavaScript (wrapped in a custom QSlotObjectBase subclass).

This is an overload that should be used when sender and receiver are different objects.

The signal_index is an index relative to the number of methods.

Definition at line 5460 of file qobject.cpp.

◆ connect() [2/3]

QMetaObject::Connection QObjectPrivate::connect	(	const QObject *	sender,
		int	signal_index,
		QtPrivate::QSlotObjectBase *	slotObj,
		Qt::ConnectionType	type )

static

Used by QML to connect a signal by index to a slot implemented in JavaScript (wrapped in a custom QSlotObjectBase subclass).

This version of connect assumes that sender and receiver are the same object.

The signal_index is an index relative to the number of methods.

Definition at line 5445 of file qobject.cpp.

		void **	slot,
		QtPrivate::QSlotObjectBase *	slotObjRaw,
		int	type,
		const int *	types,
		const QMetaObject *	senderMetaObject )

static

Internal version of connect used by the template version of QObject::connect (called via connectImpl) and also used by the QObjectPrivate::connect version used by QML. The signal_index is expected to be relative to the number of signals.

◆ disconnect() [1/3]

bool QObjectPrivate::disconnect	(	const QObject *	sender,
		int	signal_index,
		const QObject *	receiver,
		void **	slot )

static

Used by QML to disconnect a signal by index that's connected to a slot implemented in JavaScript (wrapped in a custom QSlotObjectBase subclass) In the QML case the slot is not a pointer to a pointer to the function to disconnect, but instead it is a pointer to an array of internal values required for the disconnect.

This is an overload that should be used when sender and receiver are different objects.

Definition at line 5502 of file qobject.cpp.

◆ disconnect() [2/3]

bool QObjectPrivate::disconnect	(	const QObject *	sender,
		int	signal_index,

static

Used by QML to disconnect a signal by index that's connected to a slot implemented in JavaScript (wrapped in a custom QSlotObjectBase subclass) In the QML case the slot is not a pointer to a pointer to the function to disconnect, but instead it is a pointer to an array of internal values required for the disconnect.

QtPrivate::QPropertyAdaptorSlotObject * QObjectPrivate::getPropertyAdaptorSlotObject ( const QMetaProperty & property )

Used by QPropertyAdaptorSlotObject to get an existing instance for a property, if available

◆ isDeclarativeSignalConnected()

bool QObjectPrivate::isDeclarativeSignalConnected ( uint signalIdx ) const

inline

Definition at line 240 of file qobject_p.h.

◆ isSignalConnected()

bool QObjectPrivate::isSignalConnected	(	uint	signalIndex,
		bool	checkDeclarative = true ) const

Returns true if the signal with index signal_index from object sender is connected.

signal_index must be the index returned by QObjectPrivate::signalIndex;

Definition at line 1732 of file qobject.cpp.

◆ signalIndex()

int QObjectPrivate::signalIndex	(	const char *	signalName,
		const QMetaObject **	meta = nullptr ) const

Returns the signal index used in the internal connections->receivers vector.

It is different from QMetaObject::indexOfSignal(): indexOfSignal is the same as indexOfMethod while QObjectPrivate::signalIndex is smaller because it doesn't give index to slots.

If meta is not \nullptr, it is set to the meta-object where the signal was found.
