ComboBox控件的iconColor樣式. 示例：

代碼：
<?xml?version="1.0"?encoding="utf-8"?>
<!--?http://blog.flexexamples.com/2008/07/03/setting-the-icon-color-on-a-combobox-control-in-flex/?-->
<mx:Application?xmlns:mx="http://www.adobe.com/2006/mxml"
????????layout="vertical"
????????verticalAlign="top"
????????backgroundColor="white">

????<mx:Array?id="arr">
????????<mx:Object?label="One"?/>
????????<mx:Object?label="Two"?/>
????????<mx:Object?label="Three"?/>
????????<mx:Object?label="Four"?/>
????????<mx:Object?label="Five"?/>
????????<mx:Object?label="Six"?/>
????????<mx:Object?label="Seven"?/>
????????<mx:Object?label="Eight"?/>
????????<mx:Object?label="Nine"?/>
????????<mx:Object?label="Ten"?/>
????</mx:Array>

????<mx:ApplicationControlBar?dock="true">
????????<mx:Form?styleName="plain">
????????????<mx:FormItem?label="iconColor:">
????????????????<mx:ColorPicker?id="colorPicker"?/>
????????????</mx:FormItem>
????????</mx:Form>
????</mx:ApplicationControlBar>

????<mx:ComboBox?id="comboBox"
????????????dataProvider="{arr}"
????????????iconColor="{colorPicker.selectedColor}"?/>

</mx:Application>

也可以通過CSS設置：
<?xml?version="1.0"?encoding="utf-8"?>
<!--?http://blog.flexexamples.com/2008/07/03/setting-the-icon-color-on-a-combobox-control-in-flex/?-->
<mx:Application?xmlns:mx="http://www.adobe.com/2006/mxml"
????????layout="vertical"
????????verticalAlign="top"
????????backgroundColor="white">

????<mx:Style>
????????ComboBox?{
????????????iconColor:?red;
????????}
????</mx:Style>

????<mx:Array?id="arr">
????????<mx:Object?label="One"?/>
????????<mx:Object?label="Two"?/>
????????<mx:Object?label="Three"?/>
????????<mx:Object?label="Four"?/>
????????<mx:Object?label="Five"?/>
????????<mx:Object?label="Six"?/>
????????<mx:Object?label="Seven"?/>
????????<mx:Object?label="Eight"?/>
????????<mx:Object?label="Nine"?/>
????????<mx:Object?label="Ten"?/>
????</mx:Array>

????<mx:ComboBox?id="comboBox"
????????????dataProvider="{arr}"?/>

</mx:Application>

也可以通過as的方法實現：
<?xml?version="1.0"?encoding="utf-8"?>
<!--?http://blog.flexexamples.com/2008/07/03/setting-the-icon-color-on-a-combobox-control-in-flex/?-->
<mx:Application?xmlns:mx="http://www.adobe.com/2006/mxml"
????????layout="vertical"
????????verticalAlign="top"
????????backgroundColor="white">

????<mx:Script>
????????<![CDATA[
????????????import?mx.events.ColorPickerEvent;

????????????private?function?colorPicker_change(evt:ColorPickerEvent):void?{
????????????????comboBox.setStyle("iconColor",?evt.color);
????????????}
????????]]>
????</mx:Script>

????<mx:Array?id="arr">
????????<mx:Object?label="One"?/>
????????<mx:Object?label="Two"?/>
????????<mx:Object?label="Three"?/>
????????<mx:Object?label="Four"?/>
????????<mx:Object?label="Five"?/>
????????<mx:Object?label="Six"?/>
????????<mx:Object?label="Seven"?/>
????????<mx:Object?label="Eight"?/>
????????<mx:Object?label="Nine"?/>
????????<mx:Object?label="Ten"?/>
????</mx:Array>

????<mx:ApplicationControlBar?dock="true">
????????<mx:Form?styleName="plain">
????????????<mx:FormItem?label="iconColor:">
????????????????<mx:ColorPicker?id="colorPicker"
????????????????????????change="colorPicker_change(event);"?/>
????????????</mx:FormItem>
????????</mx:Form>
????</mx:ApplicationControlBar>

????<mx:ComboBox?id="comboBox"
????????????dataProvider="{arr}"
????????????iconColor="{colorPicker.selectedColor}"?/>

</mx:Application>
