Question

<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);
                }
            }

当我没有将它放在转发器标签下时，组件是从XML创建的，但是如果我这样做，则组件不会被创建。

任何问题。

Answer 1

好的，问题是Repeater内部的id='panel'与正常情况有点不同。因为可以重复这些组件，如果你可以设置id，那么对于所有这些组件都是相同的。这就是为什么名称（在你的情况下是panel）实际上是一个数组（在这种情况下是一个HBox的数组）。

如果要将子项添加到第一个子项，则需要选择第一个数组元素 -

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

Answer 2

你需要许多HBox或许多组件吗？通常，Repeater不用于嵌套的东西，例如你的例子。此外，您不应该设置Repeater的孩子的'id'属性。如果你需要一个复杂的组件，你应该从HBox继承并将as3代码粘贴到它中。

可能你必须将Repeater 包装成 HBox。然后，您不应将您的项目添加到面板中。它们应该在Repeater的dataProvider中指定。
