Good point besides the general sizing/measuring I am wasting the rest... it
simplifies it a little too. I don't use the spacers often, but I do use them
to solve quick layouts for clients who must have a things displayed in a
certain way.
Class:
//Declare package.
package spark.components
{
import spark.primitives.supportClasses.GraphicElement;
//Create child class of the GraphicElement class.
public class Spacer extends GraphicElement
{
//----------------------------------------
// Constructor
//----------------------------------------
public function Spacer()
{
super();
}
}
}

@Mark Instead of Rect, you'd better use GraphicElement directly (Rect
extends FilledElement extends StrokedElement extends GraphicElement). I
suppose the performance should be better than that of mx:Spacer because
that inherits from UIComponent and GraphicElement does not. Though I think
the gain would be marginal since you typically don't use Spacers all over
the place.
That said, I remember some discussion on this list on the topic of
composing behaviours into components rather than inheriting them. A Spacer
would in that case only have the measuring/sizing behaviour and nothing
more. Don't know whether anyone has made any progress in this field though.
@Jeffry I suppose that in time we may want to drop the mx components or at
least give a developer the option to only target the Spark component set.
In that case, you would require a complete Spark component set, containing
even such trivial components like a Spacer.
