As JP said, make sure your UIComponent reserves some space by setting
width/height on it.
<mx:UIComponent id="uic" width="200" height="200"/>
With more work you could make UIComponent look at its child sprites and
report measurements and then it will size to fit. But for now, just make
some space.
Then your code will just pass in uic:
e = new AddSprites(uic);
And AddSprites would call addChild on that thing.
