It might work, but you really should look into reading some tutorials on the
lifecycle of Flex components. Here's a few brief things:
* You want to create child components in the createChildren() method, not in
your constructor. Your component may be instantiated long before it needs to
have its children created.
* Override the measure() function to set measuredWidth and measuredHeight,
but the actual size will be set by your container
* Override updateDisplaylist() to size and move your child components. Get
their preferred sizes using child.getExplicitOrMeasuredWidth / Height in
measure(), but set them using setActualSize(), not by setting the width and
height. Position them with move()
* There's a lot of good tutorials out there, google is your friend :)
