Detailed Description

The base class of scene nodes that can be aggregated by Qt3D::QEntity instances as a component.

A Qt3D::QComponent provides a vertical slice of behavior that can be assigned to and sometimes shared across Qt3D::QEntity instances.

Qt3D::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 Qt3D::QTransform, Qt3D::QMesh, and Qt3D::QMaterial components.

See also Qt3D::QEntity.

Member Function Documentation

QComponent::QComponent(QNode * parent = 0)

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()

[virtual protected] void QComponent::copy(const QNode * ref)

QVector<QEntity *> QComponent::entities() const

Returns a QVector containing all the entities that reference this component.
