1204498 - Implement WebGLContextEvent

Status: RESOLVED FIXED

(Core :: Graphics: CanvasWebGL, defect)

Description

[Florian Scholz (Open Web Docs)]

WebGL 1.0 https://www.khronos.org/registry/webgl/specs/latest/1.0/#5.15

"WebGL generates a WebGLContextEvent event in response to a status change to the WebGL rendering context"[...]

I found this in the source, but commented: https://dxr.mozilla.org/mozilla-central/source/dom/webidl/WebGLRenderingContext.webidl#769

/*[Constructor(DOMString type, optional WebGLContextEventInit eventInit)]
interface WebGLContextEvent : Event {
    readonly attribute DOMString statusMessage;
    };*/

// EventInit is defined in the DOM4 specification.
/*dictionary WebGLContextEventInit : EventInit {
    DOMString statusMessage;
    };*/

Blink, WebKit and IE implement WebGLContextEvent.

Jeff, is this "just" implementation work, or is there any discussion that needs to happen?

Just implementation work.

We also seem to be missing webglcontextcreationerror support?  We do cover webglcontextlost and webglcontextrestored.

Docs were written back then as well, https://bugzilla.mozilla.org/show_bug.cgi?id=1271478#c54
