Bug 49073 – Move resumeAnimations/suspendAnimations from Frame to AnimationController.

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Chris Marrin]

Darin doesn't want to increase the API of Frame, so these should be moved to AnimationController.

I think it would be cleaner to rename the existing function resumeAnimationsForThisFrameOnly or something like that, and have a new function with the loop in it, instead of using a magic value of 0 to mean "loop through subframes".

Right, Chris is going to add new methods to AnimationController.

Too much copied code here. This should just do
suspendAnimationsForDocument(m_frame->document());

Same, just call resumeAnimationsForDocument(m_frame->document());

> WebCore/page/animation/AnimationController.cpp:311
> +    /*

> +    if (!document) {

Remove!
