Unable to get children from VBox

[Seema Makkar <se...@aricent.com>]

Hello all,

This is very simple example, I want to get child from click method through rawChildren but giving null values.

Below is the implementation, please help. I need to add List at runtime.


<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"  creationComplete="application1_creationCompleteHandler(event)"
                     xmlns:s="library://ns.adobe.com/flex/spark"
                     xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">

      <fx:Script>
            <![CDATA[
                  import mx.controls.Alert;
                  import mx.controls.List;
                  import mx.events.FlexEvent;
                  protected var wBox:DisplayObject;
                  var lstControl:List;
                  protected function b1_clickHandler(event:MouseEvent):void
                  {
                        wBox=vbox.rawChildren.getChildByName("lstControl");
                        Alert.show(wBox+":::::::::::;");
                  }

                  protected function application1_creationCompleteHandler(event:FlexEvent):void
                  {

                        lstControl= new List();
                        vbox.addChild(lstControl);
                        //vbox.addChild();
                  }

            ]]>
      </fx:Script>

      <fx:Declarations>
            <!-- Place non-visual elements (e.g., services, value objects) here -->
      </fx:Declarations>
      <mx:VBox id="vbox" creationPolicy="All">
            <s:Button id="b1" click="b1_clickHandler(event)">

            </s:Button>
            <s:Button id="b2">

            </s:Button>


      </mx:VBox>
</s:Application>


Thanks,
Seema

>wBox=vbox.rawChildren.getChildByName("lstControl");

>lstControl= new List();
>vbox.addChild(lstControl);

This probably belongs on the user list. So, continued the discussion there. getChildByName() works based on the child's name, not the name of a variable that you used to instantiate and add the child.

Also, there is no need to use rawChildren here.

If in your b1_clickHandler you said:

Alert.show( vbox.numChildren) you should see it has 3.
