Apache flex 运行时的Flex组件 受保护的函数creationCompleteHandler（）：void { //警报显示（“初始2”）； var-components:Array=getComponentsFromXML（xml.component）； 变量i:int=0； var n:int=组件长度； 对于（i；i

当我不把它放在repeater标记下时，组件是从XML创建的，但是如果我这样做了，那么组件就不会被创建

任何问题

<mx:Repeater id="rep" dataProvider="{headingData.component}">
        <mx:HBox id="panel" label="{rep.currentItem.title}" 
width="100%" height="100%">
        </mx:HBox>
    </mx:Repeater>

protected function creationCompleteHandler():void
            {
                //Alert.show("init2");
                var components:Array = getComponentsFromXML(xml.component);
                var i:int = 0;
                var n:int = components.length;
                for (i; i < n; i++)
                {
                    panel.addChild(components[i] as DisplayObject);
                }
            }

您需要许多HBox还是其中的许多组件？通常，中继器不用于嵌套的对象，如您的示例中所示。此外，您不应该设置中继器的孩子的“id”属性。 如果您需要一个复杂的组件，您应该从HBox继承并将as3代码粘贴到其中

---

可能，您必须将中继器包装到HBox中。那么你就不应该把你的项目添加到面板中。它们应该在中继器的数据提供程序中指定。

好的，问题是中继器内部的

id='panel'

工作原理与正常情况稍有不同。因为这些组件可以重复，如果您只需设置id，那么所有组件的id都是相同的。这就是为什么名称（在您的示例中是

面板

）实际上是一个数组（在本例中是一个HBox数组）

如果要将子元素添加到第一个元素，则需要选择第一个数组元素-

为什么HBox在中继器中？你想拥有更多的HBox吗？我如何在不指定任何ID或其他参数的情况下动态放置它？如果你能解释它应该做什么，可能会更容易帮助你。如果替换panel.addChild（组件[i]作为DisplayObject）；使用我粘贴的行，它会将这些子项添加到第一个HBox中。

 panel[0].addChild(components[i] as DisplayObject);
