设置NumericStepper控件不可用状态的上下箭头颜色。

NumericStepper控件的 disabledIconColor样式学习。
示例：

代码：

<? xml version="1.0" encoding="utf-8" ?>
<!--  http://blog.flexexamples.com/2008/05/25/setting-the-icon-color-on-a-disabled-numericstepper-control-in-flex/  -->
< mx:Application  xmlns:mx ="http://www.adobe.com/2006/mxml"
        layout ="vertical"
        verticalAlign ="middle"
        backgroundColor ="white" >

     < mx:Style >
        NumericStepper {
            disabledIconColor: red;
        }
     </ mx:Style >

     < mx:ApplicationControlBar  dock ="true" >
         < mx:Form  styleName ="plain" >
             < mx:FormItem  label ="enabled:" >
                 < mx:CheckBox  id ="checkBox"  selected ="true"   />
             </ mx:FormItem >
         </ mx:Form >
     </ mx:ApplicationControlBar >

     < mx:NumericStepper  id ="numericStepper"
            enabled =" {checkBox.selected} "   />

</ mx:Application >

在MXML标签的属性实现：

<? xml version="1.0" encoding="utf-8" ?>
<!--  http://blog.flexexamples.com/2008/05/25/setting-the-icon-color-on-a-disabled-numericstepper-control-in-flex/  -->
< mx:Application  xmlns:mx ="http://www.adobe.com/2006/mxml"
        layout ="vertical"
        verticalAlign ="middle"
        backgroundColor ="white" >

     < mx:ApplicationControlBar  dock ="true" >
         < mx:Form  styleName ="plain" >
             < mx:FormItem  label ="enabled:" >
                 < mx:CheckBox  id ="checkBox"  selected ="true"   />
             </ mx:FormItem >
             < mx:FormItem  label ="disabledIconColor:" >
                 < mx:ColorPicker  id ="colorPicker"   />
             </ mx:FormItem >
         </ mx:Form >
     </ mx:ApplicationControlBar >

     < mx:NumericStepper  id ="numericStepper"
            enabled =" {checkBox.selected} "
            disabledIconColor =" {colorPicker.selectedColor} "   />

</ mx:Application >

也可以通过AS的方法实现:

<? xml version="1.0" encoding="utf-8" ?>
<!--  http://blog.flexexamples.com/2008/05/25/setting-the-icon-color-on-a-disabled-numericstepper-control-in-flex/  -->
< mx:Application  xmlns:mx ="http://www.adobe.com/2006/mxml"
        layout ="vertical"
        verticalAlign ="middle"
        backgroundColor ="white" >

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

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

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

     < mx:NumericStepper  id ="numericStepper"
            enabled =" {checkBox.selected} "   />

</ mx:Application >
