QAbstractAspect::QAbstractAspect(QObject *parent = nullptr)
Constructs a new QAbstractAspect with parent
[protected] template <typename Frontend> void QAbstractAspect::registerBackendType(const Qt3DCore::QBackendNodeMapperPtr &functor)
Registers backend with functor.
[protected] void QAbstractAspect::registerBackendType(const QMetaObject &obj, const Qt3DCore::QBackendNodeMapperPtr &functor)
Registers backend with obj and functor.
[protected] Qt3DCore::QNodeId QAbstractAspect::rootEntityId() const
Returns root entity node id.
A shared pointer for QAspectJob.
A shared pointer for QBackendNodeMapper.
Convenience macro for registering AspectType for instantiation by the currently set Qt3DCore::QAspectFactory. This makes it possible to create an instance of AspectType in the aspect thread by later passing name to Qt3DCore::QAspectEngine::registerAspect(const QString &name).
Note: It is also possible to register a new aspect without using this macro by instead using Qt3DCore::QAspectEngine::registerAspect(QAbstractAspect *aspect) which will handle moving a previously created aspect instance to the aspect thread context.
KDAB has published a few articles about writing custom Qt3D aspects on their blog. These provide an excellent starting point if you wish to learn more about it.
