[flexcoders] How to dispatch event from ItemRenderer?

[Troy Simpson]

I have created a List with a custom ItemRenderer.  The ItemRenderer creates
a label and two Radio Buttons for each item in the list.  When one of the
RadioButtons is selected, how would I notify other components that the a
radio button was selected?  Would I capture the click event in the
ItemRenderer and then dispatch it to the parent QuestionList Class or is
there another way to do this?

Here is an example of what I am trying to acomplish.  Thanks.

Here is my QuestionList Class:
------------------
package
{
 import mx.controls.List;
 import mx.collections.ArrayCollection;
 import mx.core.ClassFactory;


 public class QuestionList extends List
 {
  private var qItems:ArrayCollection;
  public function QuestionList()
  {
   //TODO: implement function
   super();
   this.qItems = new ArrayCollection();
   this.itemRenderer = new ClassFactory(ListItemRenderer);
   addQItem("Are you tall?");
   addQItem("Are you smart?");
   addQItem("Are you quick?");
   addQItem("Are you slow?");
   this.dataProvider = this.qItems;
  }

  public function addQItem(s:String):void
  {
   var o:Object = new Object();
   o.label = s;
   this.qItems.addItem(o);
  }
 }
----------------
ListItemRenderer Class:
------------------
package
{
 import mx.containers.Canvas;
 import mx.controls.RadioButton;
 import mx.controls.Label;
 import mx.controls.RadioButtonGroup;

 public class ListItemRenderer extends Canvas
 {
  private var lbl:Label;
  private var rdoYes:RadioButton;
  private var rdoNo:RadioButton;
  private var rdoGrp:RadioButtonGroup;
  //
  public function ListItemRenderer()
  {
   //TODO: implement function
   super();
   this.lbl = new Label();
   this.rdoNo = new RadioButton();
   this.rdoNo.label = "No";
   this.rdoNo.setStyle("right",10);
   this.rdoYes = new RadioButton();
   this.rdoYes.label = "Yes";
   this.rdoYes.setStyle("right",60);
   this.rdoGrp = new RadioButtonGroup();
   this.rdoNo.group = this.rdoGrp;
   this.rdoYes.group = this.rdoGrp;
   this.addChild(this.lbl);
   this.addChild(this.rdoYes);
   this.addChild(this.rdoNo);
  }
  override public function set data(value:Object):void
  {
   this.lbl.text = value.label;
  }
 }
}
