你好我有这个按钮栏:
<s:ButtonBar id="channelsBtnBar" requireSelection="true" width="100%" horizontalCenter="0"
skinClass="skins.TvButtonBarSkin"
change="channelsBtnBar_changeHandler(event)">
<s:dataProvider>
<s:ArrayList>
<fx:Object icon="@Embed('assets/ch1.png')"/>
<fx:Object icon="@Embed('assets/ch2.png')"/>
<fx:Object icon="@Embed('assets/ch3.png')"/>
<fx:Object icon="@Embed('assets/ch4.png')"/>
<fx:Object icon="@Embed('assets/ch5.png')"/>
<fx:Object icon="@Embed('assets/ch6.png')"/>
<fx:Object icon="@Embed('assets/ch7.png')"/>
<fx:Object icon="@Embed('assets/ch8.png')"/>
<fx:Object icon="@Embed('assets/ch9.png')"/>
</s:ArrayList>
</s:dataProvider>
</s:ButtonBar>
我怎样才能在父组件的创建完成中选择任何项目?如果不将requireSelection设置为false并将selectedItem设置为-1,这是否可能?
