Flex combox icon怎么居中

[Embed(source="sts_unfilled.gif")]
private var cccCls:C
private function aaa():void{
list.addItem({data:"aaa",label:"aaa"});
list.addItem({data:"bbb",label:"bbb"});
list.addItem({data:"ccc",label:"ccc"});
protected function combobox1_openHandler(event:DropdownEvent):void
statusCombox.dropdown.iconFunction=getI
statusCombox.dropdown.horizontalCenter=0;
statusCombox.dropdown.verticalCenter=0;
private function getIcon(item:Object):Class{
if(item.data=="aaa"){
return aaaC
}else if(item.data=="bbb"){
return bbbC
}else if(item.data=="ccc"){
return cccC
&/fx:Script&
&mx:ComboBox id="statusCombox" x="198" y="97" dataProvider="{list}" open="combobox1_openHandler(event)"/&
如上，icon和text是不垂直对齐的，怎么才能对其
其他相似问题
相关参考资料开始时，我以为用'selected': true ，就可以了，最后给想要选中的项加上去后，发现还是只能选中第一项，最后查看官方文档
NameParameterDescription
Return the options object.
Return the loaded data.
Load the locale list data.
Request the remote list data. Pass the 'url' parameter to override the original URL value.
Code example:
$('#cc').combobox('reload');
// reload list data using old URL
$('#cc').combobox('reload','get_data.php');
// reload list data using new URL
Set the combobox value array.
Code example:
$('#cc').combobox('setValues', ['001','002']);
Set the combobox value.
Code example:
$('#cc').combobox('setValue', '001');
Clear the combobox value.
Select the specified item.
Unselect the specified item.
setValues，就可以解决这个问题。稍微注意下，这个属性要写到加载数据的后面，要不然它哪找的到啊。这个属性还有个好处，就是在添加的VALUES自由的设置前后顺序，这样，结合报表的话，id可以作为字段传过去，text作为显示，报表的列名就可以自由的控制。

怎么在这个方法中& public function myTestDispaly(event:flash.events.Event):void{

得到&& combox 中的值？
各位 谢谢了
采纳的答案
看看datachange的API
dataChange
Event Object Type: mx.events.FlexEvent
property FlexEvent.type = mx.events.FlexEvent.DATA_CHANGE
Dispatched when the data property changes.
When you use a component as an item renderer, the data property contains an item from the dataProvider. You can listen for this event and update the component when the data property changes.
The FlexEvent.DATA_CHANGE constant defines the value of the type property of the event object for a dataChange event.
The properties of the event object have the following values:
Property Value
bubbles false
cancelable false
currentTarget The Object that defines the event listener that handles the event. For example, if you use myButton.addEventListener() to register an event listener, myButton is the value of the currentTarget.
target The Object that
it is not always the Object listening for the event. Use the currentTarget property to always access the Object listening for the event.
我觉得这样应该可以
public function myTestDispaly(event:flash.events.Event):void{
mx.controls.Alert.show();
event.currentTarget.selectedItem.label + " " +
event.currentTarget.selectedIndex；
