詳細描述

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 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.

isShareable : bool

Holds the shareable flag of the QComponent 。 QComponent can be shared across several entities if true .

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

構造新的 QComponent 實例與 parent as the parent.

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

[虛擬] QComponent:: ~QComponent ()

Destroys the instance of QComponent. The destructor is virtual.

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

Indicates that a reference has been added to entity .

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

返迴 QVector containing all the entities that reference this component.

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

Indicates that a reference has been removed from entity .
