Constructor & Destructor Documentation

QQmlBoundSignal()

QQmlBoundSignal::QQmlBoundSignal	(	QObject *	target,
		int	signal,
		QObject *	owner,
		QQmlEngine *	engine
	)

signal MUST be in the signal index range (see QObjectPrivate::signalIndex()). This is different from QMetaMethod::methodIndex().

setEnabled()

void QQmlBoundSignal::setEnabled

bool

enabled

)

This property holds whether the item will emit signals.

The QQmlBoundSignal callback will only emit a signal if this property is set to true.

By default, this property is true.

References enabled.

takeExpression()

void QQmlBoundSignal::takeExpression

(

QQmlBoundSignalExpression *

e

)

Sets the signal expression to e.

The QQmlBoundSignal instance takes ownership of e (and does not add a reference).
