WebGLContextEvent: WebGLContextEvent() constructor

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2016.

See full compatibility

Note: This feature is available in Web Workers.

The WebGLContextEvent() constructor creates a new WebGLContextEvent object.

Note: You typically don't need to call this constructor; the browser creates these objects automatically when WebGL context events get fired. To manually trigger a webglcontextlost event, use WEBGL_lose_context.loseContext().

A string indicating the type of the event. It is case-sensitive and should be one of webglcontextcreationerror, webglcontextlost, or webglcontextrestored.
