Just a note : I can't create a MediaControl without a parent (it gives me a Null Object error) but the parent parameter is marked as optional. So as a workaround I have to create a "dummy" mediaplayer that will actually contain my fake output element. And in the IDE (I don't know either if this is a bug), when the Null object occurs into the declaration part of the class (or outside of any function/procedure), the balloon pops out somewhere inside the stack backtrace panel. (I first thought that the IDE itself was crashing ...)
