Detailed Description
The base class of scene nodes that can be aggregated by Qt3DCore::QEntity instances as a component.
A Qt3DCore::QComponent provides a vertical slice of behavior that can be assigned to and sometimes shared across Qt3DCore::QEntity instances.
Qt3DCore::QComponent subclasses are often aggregated in groups that impart useful behavior to the aggregating entity. For example, to have an Entity that gets drawn by the Qt3D renderer aspect, an entity would most likely aggregate Qt3DCore::QTransform, Qt3DRender::QMesh, and Qt3DRender::QMaterial components.

Member Function Documentation
QComponent::QComponent(QNode *parent = Q_NULLPTR)
Constructs a new QComponent instance with parent as the parent.
Note: a QComponent should never be instanced directly, instance one of the subclasses instead.
QComponent::~QComponent()
Destroys the instance of QComponent.
[virtual protected] void QComponent::copy(const QNode *ref)
[signal] void QComponent::enabledChanged(bool enabled)
QVector<QEntity *> QComponent::entities() const
Returns a QVector containing all the entities that reference this component.
[slot] void QComponent::setShareable(bool shareable)
The QComponent can be shared across several entities if shareable is true.
Note: Setter function for property shareable.
See also shareable().
bool QComponent::shareable() const
Returns whether the QComponent is shareable across entities or not.
Note: Getter function for property shareable.
See also setShareable().
