XRCubeLayer: redraw event

Limited availability

The redraw event is sent to the XRCubeLayer object when the underlying resources of the layer are lost or when the XR Compositor can no longer reproject the layer. If this event is sent, authors should redraw the content of the layer in the next XR animation frame.

See also the needsRedraw property which is also available to XRCubeLayer objects through inheritance from XRCompositionLayer.

Syntax

Use the event name in methods like addEventListener(), or set an event handler property.

addEventListener("redraw", (event) => { })

onredraw = (event) => { }

Event type

An XRLayerEvent. Inherits from Event.

Examples

Using the redraw event

You can pass redraw to addEventListener():

cubeLayer.addEventListener("redraw", (event) => {
  // redraw the layer
});

Alternatively, you can use the onredraw event handler property to establish a handler for the redraw event:

cubeLayer.onredraw = (event) => {
  // redraw the layer
};
