XRCylinderLayer: redraw event
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The redraw
event is sent to the XRCylinderLayer
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 XRCompositionLayer.needsRedraw
property which is also available to XRCylinderLayer
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
.
Event properties
Examples
Using the redraw
event
You can pass redraw
to addEventListener()
:
cylinderLayer.addEventListener("redraw", (event) => {
// redraw the layer
});
Alternatively, you can use the onredraw
event handler property to establish a handler for the redraw
event:
cylinderLayer.onredraw = (event) => {
// redraw the layer
};
