Bug 67825 – Implement a WebKitAnimationEvent constructor for JSC

• Component: DOM
• Status: RESOLVED FIXED

[Kentaro Hara]

We have been working on implementing constructors of Events. WebKitAnimationEvent should have a constructor. 

There is no spec for the WebKitAnimationEvent constructor, since it is WebKit-specific. Based on the current IDL of initWebKitAnimationEvent(), the IDL of the WebKitAnimationEvent constructor should be as follows.                                                          

[Constructor(DOMString type, optional WebKitAnimationEvent eventInitDict)]     
dictionary WebKitAnimationEventInit : EventInit {
    DOMString animationName;
    double elapsedTime;
}

The Constructor would be on the WebKitAnimationEvent, not the WebKitAnimationEventInit.

This is not what the IDL would look like.  The constructor would be on the Event itself, not the Init.

Sorry.

Correct IDL:

[Constructor(DOMString type, optional WebKitAnimationEventInit eventInitDict)]
dictionary WebKitAnimationEventInit : EventInit {
    DOMString animationName;
    double elapsedTime;
}

Sorry for the confusion. I omitted the interface part since this patch does not change it....

[Constructor(DOMString type, optional WebKitAnimationEventInit eventInitDict)]
interface WebKitAnimationEvent : Event {
    ...;
}

dictionary WebKitAnimationEventInit : EventInit {
    DOMString animationName;
    double elapsedTime;
}

I will correct Changelog as above. Thanks!

Why were no animation people cc'd on this?

[Sam Weinig]

It's not really animation related, just progressing through all the events, adding constructors.
