AS3 - Can I detect change of value of a variable using addEventListener?

Question

Is it possible to use EventListener to Listen to a variable and detect when the value of that variable changes? Thanks.

You used to be able to do something similar in AS2 using Object.watch. I don't see a direct equivalent, but it looks like mx.binding.utils.ChangeWatcher will give you similar functionality for any variables that are bindable.

I don't know of a way to do it in AS3 for non-bindable variables, but if the variable you want to watch is bindable (or if you can modify it to be binadable) then ChangeWatcher might give you what you want.
