Flex 3：按钮上没有蓝色对焦环
我的按钮周围没有蓝色聚焦环，尽管它有焦点。
我有一个带有 RadioButtonGroup 和 Button 的组件。在 RadioButtonGroup 中进行选择后，焦点将切换到 Button。我在 VBox 上添加了 click="focusManager.setFocus(myCloseButton)" 。
之后，选择一个单选按钮，如果用户单击空格键，则会触发该按钮。 因此，据我了解，焦点已切换到按钮。但是，该按钮周围没有蓝色聚焦环。如何获得对焦环？
（我有visible =“false”。在一些效果完成后，我将它们变为可见。所以，不要让这让你困惑。）
<mx:VBox id="radioVBox" visible="false" click="focusManager.setFocus(myCloseButton)" >
<mx:RadioButtonGroup id="rgb1" itemClick="goClickHandler(event); "/>
<mx:RadioButton groupName="rgb1" label="{answerA}" value="{answerA}" />
<mx:RadioButton groupName="rgb1" label="{answerB}" value="{answerB}" />
<mx:RadioButton groupName="rgb1" label="{answerC}" value="{answerC}" />
</mx:VBox>
<mx:Button id="myCloseButton" label="Close"
width="100" height="40"
fontSize="20" fontWeight="bold"
click="closeHandler(event)"
visible="false" fontFamily="Verdana" />
有什么建议吗？
谢谢。

My button doesn't have a blue focus ring around it, even though it has focus.
I've got a component with a RadioButtonGroup and a Button. After a selection is made in the RadioButtonGroup, focus is switched to the Button. I added click="focusManager.setFocus(myCloseButton)" on the VBox.
After, a radioButton is selected, if the user clicks the spacebar the Button fires.
So, as I understand it focus was switched to the button. But, the button doesn't get a blue focus ring surrounding it. How do I get the focus ring?
(I have visible="false". I turn them to visible, after some effects are finished. So, don't let that throw you.)
<mx:VBox id="radioVBox" visible="false" click="focusManager.setFocus(myCloseButton)" >
<mx:RadioButtonGroup id="rgb1" itemClick="goClickHandler(event); "/>
<mx:RadioButton groupName="rgb1" label="{answerA}" value="{answerA}" />
<mx:RadioButton groupName="rgb1" label="{answerB}" value="{answerB}" />
<mx:RadioButton groupName="rgb1" label="{answerC}" value="{answerC}" />
</mx:VBox>
<mx:Button id="myCloseButton" label="Close"
width="100" height="40"
fontSize="20" fontWeight="bold"
click="closeHandler(event)"
visible="false" fontFamily="Verdana" />
Any suggestions?
Thank you.
