奇怪的弹性行为与状态和单选按钮

我有以下flex组件:

<?xml version="1.0" encoding="utf-8"?>
<s:BorderContainer xmlns:fx="http://ns.adobe.com/mxml/2009" 
         xmlns:s="library://ns.adobe.com/flex/spark" 
         xmlns:mx="library://ns.adobe.com/flex/mx" 
         width="400" 
         height="300"
         borderColor.male="blue"
         borderColor.female="#FF00F6"
         initialize="init(event)">

    <fx:Script>
        <![CDATA[
            import mx.events.FlexEvent;
            protected function genderChanged(event:Event):void
            {               
                setByRadioGroup();
            }

            protected function init(event:FlexEvent):void
            {
                currentState = "male";
                //setByRadioGroup()
            }

            protected function setByRadioGroup():void {
                currentState = genderGroup.selectedValue as String;
            }

        ]]>
    </fx:Script>

    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
        <s:RadioButtonGroup id="genderGroup" change="genderChanged(event)">

        </s:RadioButtonGroup>
    </fx:Declarations>
    <s:states>
        <s:State name="male"/>
        <s:State name="female"/>
    </s:states>
    <s:Form>
        <s:FormItem label="name">
            <s:TextInput name="nameField" id="nameField"/>
        </s:FormItem>
        <s:FormItem label="gender">
            <s:RadioButton label="male" groupName="genderGroup" selected.male="true"/>
            <s:RadioButton label="female" groupName="genderGroup" selected.female="true"/>
        </s:FormItem>
    </s:Form>
</s:BorderContainer>

我试图通过将currentState设置为“male”来初始化组件的整个状态(包括选定的单选按钮)。这最初工作(选择正确的单选按钮,边框为蓝色): initial state

但是当我点击另一个单选按钮时,ui有时会以奇怪的状态结束 - 无线电选择会恢复为原始状态,但边框颜色会发生变化: after click

这里有某种种族缺失吗?

即时使用flex 4.6.0和flash builder 4.7

1 个答案:

答案 0 :(得分:1)

你必须告诉其他状态的选定值,因为它的工作方式与预期的一样:

<s:RadioButton label="male" groupName="genderGroup" selected.male="true" selected.female="false"/>
<s:RadioButton label="female" groupName="genderGroup" selected.female="true" selected.male="false"/>

虽然我不想用状态标识符设置所选值。 我将在组件中添加状态更改侦听器,并在其处理函数中设置所选值。 但这只是个人选择......
