Qt3DRender::QRenderSettings::RenderPolicy | renderPolicy() const

## Public Slots

void | setActiveFrameGraph(Qt3DRender::QFrameGraphNode *activeFrameGraph)
void | setRenderPolicy(Qt3DRender::QRenderSettings::RenderPolicy renderPolicy)

## Signals

void | activeFrameGraphChanged(Qt3DRender::QFrameGraphNode *activeFrameGraph)

## Detailed Description

The QRenderSettings component must be set as a component of the scene root entity. It specifies render policy and picking settings, as well as hosts the active FrameGraph.

## Member Type Documentation

### enum QRenderSettings::RenderPolicy

The render policy.

Constant | Value | Description
--- | --- | ---
`Qt3DRender::QRenderSettings::OnDemand` | `0` | The FrameGraph is rendered only when something changes.
`Qt3DRender::QRenderSettings::Always` | `1` | The FrameGraph is rendered continuously, even if nothing has changed.
