Flex DropDownList ItemRenderer probably a bug
I am trying to make a simple change on look of Flex 4.5 Spark DropDownLis trough extending it's item renderer, anyway even a just shiny new item renderer bring me as result a items which labels is blanks. If i remove the renderer everything is fine, but with it - the items is blank white.
<s:DropDownList id="cbX" x="140" y="281" width="276" itemRenderer="comboItemRenderer" labelField="@text">
<mx:XMLListCollection>
<fx:XMLLi开发者_运维知识库st>
<node text="1" />
<node text="2" />
<node text="3" />
</fx:XMLList>
</mx:XMLListCollection>
</s:DropDownList>
item renderer :
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
autoDrawBackground="true">
<s:Label text="{data}"/>
</s:ItemRenderer>
Is it a bug, or i am doing it wrong ?
Try to use:
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
autoDrawBackground="true">
<s:Label text="{label}"/>
</s:ItemRenderer>
The data for the renderer is still the data. But if you use labelField
you rely on List's label calculation routine. So just display it.
