class Qt3DRender::QNoPicking当 FrameGraph 分支中存在一个Qt3DRender::QNoPicking 节点时，这将阻止渲染方面对该分支执行拾取选择。更多内容...

该类已弃用。我们强烈建议不要在新代码中使用它。
详细说明
当禁用时，Qt3DRender::QNoPicking 节点不会阻止拾取操作的执行。因此，切换enabled属性的状态是使Qt3DRender::QNoPicking 处于活动或非活动状态的一种方式。
在 FrameGraph 中使用多个子视口时，QNoPicking 可用于防止重叠视口或非可见视口之间的选取冲突。它还可以作为一种优化手段，避免为隐藏视口或场景中无需进行选取的区域执行不必要的工作。
