The webglcontextcreationerror
event of the WebGL API is fired if the user agent is unable to create a WebGLRenderingContext
context.
This event has a WebGLContextEvent.statusMessage
property, which can contain a platform dependent string with more information about the failure.
This event does not bubble.
Use the event name in methods like addEventListener()
, or set an event handler property.
addEventListener("webglcontextcreationerror", (event) => {});
onwebglcontextcreationerror = (event) => {};
This interface inherits properties from its parent interface, Event
.
