Subject RE: [Component] Spacer

  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.
