R – load multiple swf in HorizontalList, Flex3 Air application

You can do this by implementing a custom Border:

package your.package
{

  import flash.display.*;
  import flash.geom.*;
  import flash.utils.*;

  import mx.skins.halo.HaloBorder;
  import mx.utils.GraphicsUtil;

  public class RoundedBorder extends HaloBorder 
  {

    private var topCornerRadius:Number;
    private var bottomCornerRadius:Number;
    private var setup:Boolean;

    /**
     * Get the CSS style attributes from the element to which to apply this
     * gradient. 
     */
    private function readElementCssStyles():void
    {
      topCornerRadius = getStyle("cornerRadius") as Number;
      if (!topCornerRadius)
      { 
        topCornerRadius = 0;
      }    

      bottomCornerRadius = getStyle("bottomCornerRadius") as Number;
      if (!bottomCornerRadius) 
      {
        bottomCornerRadius = topCornerRadius;
      }  
    }

    /**
     * Paint the gradient background.
     *  
     * @param unscaledWidth
     * @param unscaledHeight
     * 
     */
    override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void
    {
      super.updateDisplayList(unscaledWidth, unscaledHeight);   
      var rectWidth:Number 
          = unscaledWidth - this.borderMetrics.left - this.borderMetrics.right;
      var rectHeight:Number 
          = unscaledHeight - this.borderMetrics.top - this.borderMetrics.bottom; 

      readElementCssStyles();

      var topRadius:Number = Math.max(topCornerRadius-2, 0);
      var bottomRadius:Number = Math.max(bottomCornerRadius-2, 0);

      GraphicsUtil.drawRoundRectComplex(this.graphics, 
                                        this.borderMetrics.left, 
                                        this.borderMetrics.top, 
                                        rectWidth, 
                                        rectHeight, 
                                        topRadius, 
                                        topRadius, 
                                        bottomRadius, 
                                        bottomRadius);
    }

  }
}

Then in your MXML application you have to define a CSS class for your VBox like this:

  <mx:Style>
    .roundedBorder
    {
      border-style:solid;
      border-thickness: 1;
      border-skin: ClassReference("your.package.RoundedBorder");
      corner-radius: 5;
    }   
  </mx:Style>

I have ripped this code out of a more complex class. Hope I did not forgot anything and that it will work as posted.

One thing you can do is to make getters and setters for the properties instead of public vars and have your class extend EventDispatcher, if it does not already do so because it is extended from a MovieClip, like:

private var _vehicleName:String;
.
.
.
public function set vehicleName(value:String):void {
  _vehicleName = value;
  dispatchEvent(new VehicleEvent(VehicleEvent.propertyChange, "vehicleName"));
}

public function get vehicleName():String {
  return _vehicleName;
}

(VehicleEvent being an extended class of Event with an extra string to signify which property changed)

Then you can add an eventlistener to the vehicles and they will dispatch events when the properties defined in this way change.
