does flex use frames?

I'm looking into developing a game using the flex SDK instead of开发者_开发百科 flash. I'm kind of not sure how to start.

One question I have - does Flex have a timeline like Flash, with frames etc? Is there a main/root timeline?

From my experience with Flex it is event-based and does not use a timeline for development. That is not to say that you cannot implement timelines using state transitions. I'm not sure what the performance would be like compared to Flash.
