Qt3d RenderStateSet does not works.

Hi! I try to add QRenderState to my Qt3DWindow(i hope they will global for all entity), but it take no effect. Is there any mistake in my code?

    view = new Qt3DExtras::Qt3DWindow();
	QWidget* wid = QWidget::createWindowContainer(view);
	QBoxLayout * Lay = new QBoxLayout(QBoxLayout::Down, this);
	Lay->addWidget(wid);
	root = new Qt3DCore::QEntity();
	camera = view->camera();

renderStateSet = new Qt3DRender::QRenderStateSet(view->activeFrameGraph());
	
	const auto  lineWidth2 = new Qt3DRender::QLineWidth();
	lineWidth2->setValue(4.0f);
	
	const auto  pointweight = new Qt3DRender::QPointSize();
	pointweight->setValue(4.0f);
	
	const auto cullFront = new Qt3DRender::QCullFace();
	cullFront->setMode(Qt3DRender::QCullFace::FrontAndBack);

	const auto depthTest = new Qt3DRender::QDepthTest();
	depthTest->setDepthFunction(Qt3DRender::QDepthTest::LessOrEqual);
	
	
	renderStateSet->addRenderState(depthTest);
	renderStateSet->addRenderState(lineWidth2);
	renderStateSet->addRenderState(pointweight);
	renderStateSet->addRenderState(cullFront);

I find solution. The structure of entityes must include Layerfilter.

Qt3DRender::QViewport *viewport = new Qt3DRender::QViewport(view->renderSettings()->activeFrameGraph());//here must be your framegraph
	auto surselector =new Qt3DRender::QRenderSurfaceSelector(viewport);
	surselector->setSurface(view);
	auto layerfilter = new Qt3DRender::QLayerFilter(surselector);
	auto layer = new Qt3DRender::QLayer(root);//yours root entity
	layer ->setRecursive(true);
	Qt3DRender::QCameraSelector *cameraSelector = new Qt3DRender::QCameraSelector(layerfilter);
	Qt3DRender::QClearBuffers *clearBuffers = new Qt3DRender::QClearBuffers(cameraSelector);
	clearBuffers->setClearColor(QColor(100.0, 100.0, 100.0));
	cameraSelector->setCamera(view->camera());
	clearBuffers->setBuffers(Qt3DRender::QClearBuffers::AllBuffers);

	Qt3DRender::QRenderStateSet* rendstate = new Qt3DRender::QRenderStateSet(clearBuffers);
	rendstate->setParent(clearBuffers);

	Qt3DRender::QDepthTest* depth = new Qt3DRender::QDepthTest();//Without this nothing will work
	depth->setDepthFunction(Qt3DRender::QDepthTest::LessOrEqual);
	rendstate->addRenderState(depth);

	Qt3DRender::QLineWidth* lw = new Qt3DRender::QLineWidth(rendstate);//render state for example
	lw->setValue(8);
	rendstate->addRenderState(lw);

" layer " must be adde as component to entity
