Description

Create a data grid:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">
<s:DataGrid>
<s:columns>
<s:ArrayList>
<s:GridColumn itemRenderer="ItemRenderer"
dataField="foo"/>
</s:ArrayList>
</s:columns>
<s:dataProvider>
<s:ArrayList>
<fx:Object foo="bar"/>
</s:ArrayList>
</s:dataProvider>
</s:DataGrid>
</s:Application>

And an item renderer:

<?xml version="1.0" encoding="utf-8"?>
<s:GridItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">

<fx:Script>
<![CDATA[
override public function prepare(hasBeenRecycled:Boolean):void

{ trace(width); }

]]>
</fx:Script>

<s:Label text="

{label}

"/>

</s:GridItemRenderer>

The application will output:

0
4096
87

The width of the item renderer is set to 4096 before the second call to prepare. If the item renderer sets the width of its child elements to this.width the application will output

0
4096
4096

The renderer will remain too wide.
