Detailed Description#

QLayer works in conjunction with the QLayerFilter in the FrameGraph.

A QLayer can be applied to a subtree of entities by setting the recursive property to true.

 #include <Qt3DCore/QEntity>
 #include <Qt3DRender/QGeometryRenderer>
 #include <Qt3DRender/QLayer>
 #include <Qt3DRender/QLayerFilter>
 #include <Qt3DRender/QViewport>

// Scene
Qt3DCore::QEntity *rootEntity = new Qt3DCore::Qt3DCore::QEntity;

Qt3DCore::QEntity *renderableEntity = new Qt3DCore::Qt3DCore::QEntity(rootEntity);
Qt3DRender::QGeometryRenderer *geometryRenderer = new Qt3DCore::QGeometryRenderer(renderableEntity);
Qt3DRender::QLayer *layer1 = new Qt3DCore::QLayer(renderableEntity);
layer1->setRecursive(true);
renderableEntity->addComponent(geometryRenderer);
renderableEntity->addComponent(layer1);

...

// FrameGraph
Qt3DRender::QViewport *viewport = new Qt3DRender::QViewport;
Qt3DRender::QLayerFilter *layerFilter = new Qt3DRender::QLayerFilter(viewport);
layerFilter->addLayer(layer1);

class PySide6.Qt3DRender.Qt3DRender.QLayer([parent=None])#

Parameters:: parent – PySide6.Qt3DCore.Qt3DCore.QNode

Constructs a new QLayer with the specified parent.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property PᅟySide6.Qt3DRender.Qt3DRender.QLayer.recursive: bool#

Specifies if the layer is also applied to the entity subtree.

Access functions:

recursive ()
setRecursive (recursive)
