How to get FrameEvent and UserData using ActionTimeline?

cocos2d-x C++

I’m using following code to play animation, since Armature is deprecated. I want to read devide one action timeline into 4 parts, idle, attacking and so on.

_skeletalNode = CSLoader::createNode(fileName);
_timeline = CSLoader::createTimeline(fileName);
_skeletalNode->runAction(_timeline);
