<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <mx:Array id="arr">
        <mx:Object label="left" />
        <mx:Object label="center" />
        <mx:Object label="right" />
    </mx:Array>

    <mx:ApplicationControlBar dock="true">
        <mx:Form styleName="plain">
            <mx:FormItem label="textAlign:">
                <mx:ComboBox id="comboBox"
                        dataProvider="{arr}" />
            </mx:FormItem>
        </mx:Form>
    </mx:ApplicationControlBar>

    <mx:NumericStepper id="numericStepper"
            textAlign="{comboBox.selectedItem.label}"
            width="100" />

</mx:Application>

你也可以通过以下2种方式设置样式：

<mx:Style>
    NumericStepper {
        textAlign: right;
    }
</mx:Style>

<mx:Script>
    <![CDATA[
        private function init():void {
            numericStepper.setStyle("textAlign", "right");
        }
    ]]>
</mx:Script>
