[flexcoders] better to use mxml or actionscript for new component?

Fri, 21 Jul 2006 10:36:43 -0700

Just curious, is it actually more efficient to use AS instead of MXML (or vice versa) when deriving new components?  I'm talking about where it's just as easy to code it either way.  I'm just wondering about how the guts of the compiler work.

For example, take these two:

package nes {

  import mx.controls.Label;
  import mx.controls.dataGridClasses.DataGridListData;
  import flash.display.Graphics;
  import mx.controls.DataGrid;

  public class DetailBgColorRenderer extends Label {
    override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void {
      super.updateDisplayList(unscaledWidth, unscaledHeight);

      var g:Graphics = graphics;
      if (data != null) {
        if (data.backgroundColor != 0) {
          var grid:DataGrid = DataGrid(DataGridListData(listData).owner);
         
          g.beginFill(data.backgroundColor);
          g.drawRect(0, 0, unscaledWidth, unscaledHeight);
          g.endFill();
        }
        else
          g.clear();
      }
    }
  }
}



<?xml version="1.0" encoding="utf-8"?>
<mx:Label xmlns:mx="http://www.adobe.com/2006/mxml">
  <mx:Script>
    <![CDATA[
      override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void {
        super.updateDisplayList(unscaledWidth, unscaledHeight);
 
        var g:Graphics = graphics;
        if (data != null) {
          if (data.backgroundColor != 0) {
            var grid:DataGrid = DataGrid(DataGridListData(listData).owner);
          
            g.beginFill(data.backgroundColor);
            g.drawRect(0, 0, unscaledWidth, unscaledHeight);
            g.endFill();
          }
          else
            g.clear();
        }
      }     
    ]]>
  </mx:Script>
</mx:Label>
