详细说明
该类很少被直接实例化，因为它不提供任何帧图特定的行为，尽管它可以方便地用于在动态帧图中将其他节点分组。实际行为来自子类。
这些子类是

成员函数文档
[explicit] QFrameGraphNode::QFrameGraphNode(Qt3DCore::QNode *parent = nullptr)
构造函数以指定的parent 创建一个实例。
Qt3DRender::QFrameGraphNode *QFrameGraphNode::parentFrameGraphNode() const
返回指向框架图父节点的指针。
如果该节点的父节点不是框架图节点，该方法将递归查找一个框架图节点的父节点。
