Flex Modal SkinnableContainer

Question

我有这个SkinnableContainer，我需要实现什么来为这个容器创建模态？由于某些原因（mxmlContentFactory，skin），它必须是SkinnableContainer ...我不能使用弹出管理器 - 我使用Spark Move效果定位容器（它从屏幕边缘开始，然后滑出。

请问任何想法，理论和建议？ 谢谢。

EDIT 这是我的代码：（mxml）

    <s:Application width="800" height="600">
     <RightTabGroup width="100%" height="500" verticalCenter="0">
      <RightTab id="tab1">
       <RightTabHandle id="tab1handle">
        <s:Label />
       </RightTabHandle>
       <RightTabContent id="tab1content">
        <s:TextInput />
        <s:TextInput />
        <s:TextInput />
       </RightTabContent>
      </RightTab>

      <RightTab id="tab2">
       <RightTabHandle id="tab2handle">
        <s:Label />
        <s:Button />
       </RightTabHandle>
       <RightTabContent id="tab2content">
        <s:TextInput />
        <s:Button />
       </RightTabContent>
      </RightTab>

      <RightTab id="tab3">
       <RightTabHandle id="tab3handle">
       </RightTabHandle>
       <RightTabContent id="tab3content">
        <s:TextInput />
        <s:TextInput />
        <s:TextInput />
           etc...
        <s:TextInput />
       </RightTabContent>
      </RightTab>
     </RightTabGroup>

    <s:Button id="Problem 1"/>
    <s:Button id="Problem 2"/>
    <s:Button id="Problem 3"/>
      ...etc
    <s:Group id="Problem N">
    </s:Group>

    </s:Application>

<s:Application width="800" height="600"> <RightTabGroup width="100%" height="500" verticalCenter="0"> <RightTab id="tab1"> <RightTabHandle id="tab1handle"> <s:Label /> </RightTabHandle> <RightTabContent id="tab1content"> <s:TextInput /> <s:TextInput /> <s:TextInput /> </RightTabContent> </RightTab> <RightTab id="tab2"> <RightTabHandle id="tab2handle"> <s:Label /> <s:Button /> </RightTabHandle> <RightTabContent id="tab2content"> <s:TextInput /> <s:Button /> </RightTabContent> </RightTab> <RightTab id="tab3"> <RightTabHandle id="tab3handle"> </RightTabHandle> <RightTabContent id="tab3content"> <s:TextInput /> <s:TextInput /> <s:TextInput /> etc... <s:TextInput /> </RightTabContent> </RightTab> </RightTabGroup> <s:Button id="Problem 1"/> <s:Button id="Problem 2"/> <s:Button id="Problem 3"/> ...etc <s:Group id="Problem N"> </s:Group> </s:Application>

RightTabGroup是s：我的自定义布局组 RightTab是s：带皮肤的SkinnableContainer（SkinPart tabContentGroup和tabHandleGroup） RightTabHandle是s：SkinnableContainer
RightTabContent是s：SkinnableContainer
