詳細描述

A Qt3DCore::QComponent provides a vertical slice of behavior that can be assigned to and sometimes shared across Qt3DCore::QEntity 實例。

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 ，和 Qt3DRender::QMaterial components.

QComponent:: QComponent ( Qt3DCore::QNode * parent = nullptr)

Constructs a new QComponent instance with parent as the parent.

注意： a QComponent should never be instanced directly, instance one of the subclasses instead.

`[signal]` void QComponent:: addedToEntity ( Qt3DCore::QEntity * entity )

Indicates that a reference has been added to entity .

`[signal]` void QComponent:: removedFromEntity ( Qt3DCore::QEntity * entity )

Indicates that a reference has been removed from entity .

QVector < Qt3DCore::QEntity *> QComponent:: entities () const

返迴 QVector containing all the entities that reference this component.
