Re: [Flashcoders] What design pattern would this be?

[John McCormack]

I would also like to use patterns more than I do. It looks as thought 
the observer pattern might be the one in this case...


As your objects appear and disappear from your program they can register 
themselves.
They pass a function to call when an update happens and this is added to 
the list.
The list of observers' function are called to update them of the mouse 
position.

I want this class to be able to work with a runtime generated OR an

I figure it's as easy as instantiating either a RuntimeChildren or

Since it's so simple, does it even qualify as a design pattern and if so

It might be a little light but check out the reactor pattern.  It is
very useful when desiring polymorphic behaviors.

Re: [Flashcoders] What design pattern would this be?

[Jiri Heitlager]

I also still find it sometimes hard when to decide what pattern to use 
and mostly _if_ I should use a pattern. It helps me a lot to really 
think about what the responsibility is of a class and then when I notice 
it has more then one, then that is an inidicator I need to refine more. 
Sometimes refining means that I _can_ use a pattern, it doesnt always 
mean that I should use one.

I think these are those things that take a long time of experience.

Good luck.

As you wish, then go for a minimalist composite pattern my friend.

Thanks Latcho,
That is actually very helpful. Now that I look at it I can see definitely
would be over engineering in this case but it will be good practice for me.
