I'd make the border a Degrafa surface (or just a mx:Box with a border).
Add a moveEffect and a resizeEffect, put it in the same container as the
thumbnails, but last in the list so it'll be on top. If they're in a hbox or
something like that and you don't want to mess up the layout of the
container, set
myBorderComponent.includeInLayout = false;
And it will be in the same container but won't affect the layout. Then,
every time you want to hilight another thumbnail, simply call:
myBorderComponent.move(nextThumbnail.x, nextThumbnail.y);
myBorderComponent.width = nextThumbnail.width;
myBorderComponent.height = nextThumbnail.height;
And the moveEffect and resizeEffect should do the rest.

Hi everyone,
I'm looking for advice on how to easily accomplish the following task.
I already have a Flex app that displays four thumbnail images in a
vbox on the right side, and when I click on one, that image is
displayed in a larger format within the same app (left of the vbox).
What I'd like to do next is place a border/rectangle around the
thumbnail, and have that border move down to the next thumbnail using
a timer. So, I have a couple questions: (see the MTV header)
1. Is it best to use a custom image class with border or is it better
to use drawRect to place a rectangle over the mx:Image? Or use a
TileList instead of vbox and make the timer automatically scroll
through the thumbs?
I basically want to accomplish something similar to the animated
marquee/header on mtv.com (is the effect they use on the images
mx.effects.move?)
...and I'm a beginner with any custom components and animation - so
any clues/help would be appreciated.
Thanks
