Actionscript 3 contentGroup内的Flex SkinnableContainer外观访问组

我有一个skin类，在其中我在contentGroup中定义了一个组：

<s:Group id="contentGroup" left="0" right="0" top="0" bottom="0" minWidth="475" minHeight="0">
        <s:layout>
            <s:HorizontalLayout paddingLeft="0" paddingRight="0" paddingTop="0" paddingBottom="0" gap="2" />
        </s:layout>


        <s:Group id="group_nav_custom_comp_hgroup_prevnext" left="0" right="0" top="0" bottom="0" minWidth="100" minHeight="0">
            <s:layout>
                <s:HorizontalLayout paddingLeft="0" paddingRight="0" paddingTop="0" paddingBottom="0" gap="5" />
            </s:layout>
            <s:Button label="Test Button"/>
        </s:Group>

    </s:Group>

结果是我的：group_nav_custom_comp_hgroup_prevnext根本没有显示，编译时出现在其中的按钮不可见这一事实就证明了这一点。有人知道如何让它出现吗谢谢-迈克

好的，我将我的子组添加为蒙皮部分：

[SkinPart（required=“true”）] 公共变量组\导航\自定义\公司\集团\前置：集团

现在我可以从CustomComponent中的任何位置访问它。但是“group_nav_custom_comp_hgroup_prevnext”中的按钮仍然没有显示。有人知道为什么吗

contentGroup应该包含添加到SkinnableContainer的元素，而不包含其他内容。这是在父组件中管理的，而不是皮肤。因此，您可以在contentGroup的正下方添加“group_nav_custom_comp_hgroup_prevnext”组组件定义，然后在GroupNavCustomContainer中引用它

package com.viiv.digi.views.navigation
{
          import mx.core.IVisualElement;
          import mx.core.UIComponent;

          import spark.components.Group;
          import spark.components.SkinnableContainer;

          public class GroupNavCustomContainer extends SkinnableContainer
          {

                    private var m_group_prev_next:Group = null;
                    private var m_bAdded_btns:Boolean = false;
                    private var _prevbtn:UIComponent = null;


                    [SkinPart(required="true")]
                    public var group_nav_custom_comp_hgroup_prevnext:Group;



                    public function GroupNavCustomContainer()
                    {
                              super();
