The first question to whoever nucna heard of the term is as follows:
What is Code behind? It's really interesting? What is it for?
Code behind is a technique that hides the behavior (code in ActionScript) from an MXML component, or vice versa.
Huh, so they do not mention hiding the MXML behavior, just the opposite.
It's true. In one of the references that will be passed only if the trip is reviewed using the definition given above, not the back. This is something very questionable, but when browsing a bit I found a post by Mário Júnior who spoke about the technique, and he used in his example the return of the definition.
