Mouseover move 1 of 6 buttons to front for simple gallery

Question

OK this is crazy. I have tried so many solutions and nothing seems to work. I have six images on a frame as buttons with rollovers making them expand on the button frames. The issue is when the mouse goes over they only expand over the other buttons they are above stackingwise in that layer. I really was hoping to create just a simple bit of code, but it seems that things like containers and children are all needed?
My code is thus...
dig1.addEventListener(MouseEvent.MOUSE_OVER, over1);
function over1(event:MouseEvent):void
addChild(event.currentTarget);
dig2.addEventListener(MouseEvent.MOUSE_OVER, over1);
dig3.addEventListener(MouseEvent.MOUSE_OVER, over1);
dig4.addEventListener(MouseEvent.MOUSE_OVER, over1);
dig5.addEventListener(MouseEvent.MOUSE_OVER, over1);
dig6.addEventListener(MouseEvent.MOUSE_OVER, over1);
The little line of code was my most recent attempt but it pulled up an error about things I have no clue on (1118). Is there a simple code to move the current button on top with out having to say "forget AS3!" and just make a 5 frame webpage a 60 frame one?
P.S. what is the best format to import videos into a flash project? I went with a swf version, but I was not sure if the mov or other formats would be better.

Answer 1

your main timeline has dig1-dig6
your main timeline has the code:
var t = this;
t.addChild(dig1)
t is the main timeline
the main timeline adds dig1
your main timeline has a container movieclip named "container" and dig1-dig6 are inside container
your main timeline has the code:
var t = container;
t.addChild(dig1)
t is the container
the container adds dig1
if dig1 is already on the stage when you addChild(dig1), it gets moved to the top of the display list (sort of like swapping it's depth to the uppermost depth)
note to kglad:
you're right, it does not appear to be losing scope- but when running the code as is, it failed.
