Member Function Documentation

QQmlAspectEngine::QQmlAspectEngine(QObject *parent = nullptr)

Constructs a new QQmlAspectEngine with parent.

[signal] void QQmlAspectEngine::sceneCreated(QObject *rootObject)

This signal is emitted with rootObject when the scene has been instantiated. This provides a chance to manipulate the scene before passing it over to the aspect engine. Useful for convenience window classes to set up cameras and surfaces on the framegraph and event sources for the input aspect etc.

[signal] void QQmlAspectEngine::statusChanged(Qt3DCore::Quick::QQmlAspectEngine::Status status)

This signal is emitted with status when the status of the engine changes.

Qt3DCore::QAspectEngine *QQmlAspectEngine::aspectEngine() const

Returns the aspectEngine.

QQmlEngine *QQmlAspectEngine::qmlEngine() const

Returns the engine.

void QQmlAspectEngine::setSource(const QUrl &source)

Sets source as a source for the QML component to be created.

Qt3DCore::Quick::QQmlAspectEngine::Status QQmlAspectEngine::status() const

Returns the status.
