设置ComboBox控件的边框颜色.

ComboBox控件的borderColor样式学习.
示例：

代码：

<? xml version="1.0" encoding="utf-8" ?>
<!--  http://blog.flexexamples.com/2008/06/09/setting-a-border-color-on-the-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:Array >

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

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

</ mx:Application >

也可以通过css实现：

<? xml version="1.0" encoding="utf-8" ?>
<!--  http://blog.flexexamples.com/2008/06/09/setting-a-border-color-on-the-combobox-control-in-flex/  -->
< mx:Application  xmlns:mx ="http://www.adobe.com/2006/mxml"
        layout ="vertical"
        verticalAlign ="top"
        backgroundColor ="white" >

     < mx:Style >
        ComboBox {
            borderColor: 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:Array >

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

</ mx:Application >

也可以通过AS的内部函数实现

<? xml version="1.0" encoding="utf-8" ?>
<!--  http://blog.flexexamples.com/2008/06/09/setting-a-border-color-on-the-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("borderColor", 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:Array >

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

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

</ mx:Application >
