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().

Definition at line 220 of file qqmlboundsignal.cpp.

◆ ~QQmlBoundSignal()

QQmlBoundSignal::~QQmlBoundSignal ( )

Definition at line 238 of file qqmlboundsignal.cpp.

Member Function Documentation

◆ expression()

QQmlBoundSignalExpression * QQmlBoundSignal::expression ( ) const

Returns the signal expression.

Definition at line 269 of file qqmlboundsignal.cpp.

◆ removeFromObject()

void QQmlBoundSignal::removeFromObject ( )

Definition at line 256 of file qqmlboundsignal.cpp.

◆ 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.

Definition at line 293 of file qqmlboundsignal.cpp.

◆ 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).

Definition at line 279 of file qqmlboundsignal.cpp.

◆ QQmlBoundSignal_callback

void QQmlBoundSignal_callback ( QQmlNotifierEndpoint * e,
void ** a )
