Question

我的目标是在主应用程序窗口的单独子窗口中显示通过URLLoader获取的文本。最初，我使用了NativeWindow并运行良好，但是我需要实现Scrollbars，所以我一直在尝试将以前在NativeWindow类中显示的内容包装到sparks标签中，但是我遇到的问题很少。我的代码基于Adobe的示例：

 //open a new instance of the document window called from main window
                docWindow = new DocumentWindow(); 
                docWindow.open();

DocumentWindow代码：

<?xml version="1.0" encoding="utf-8"?>
<!-- aircomponents/src/myComponents/DocumentWindow.mxml -->
<s:Window xmlns:fx="http://ns.adobe.com/mxml/2009" 
    xmlns:s="library://ns.adobe.com/flex/spark" 
    xmlns:mx="library://ns.adobe.com/flex/mx" 
    width="550" height="450">
    <s:Label text="This is a document window." 
        horizontalCenter="0" verticalCenter="0"/> 
</s:Window>

所以我创建了从主窗口调用的这段代码：

var reqString:String = Global.serverURL+"imports/tkw/loginfo.jsp?InfoId="+infoId;   


                var date:Date = new Date();
                var logWindow:ContentWindow = new ContentWindow()

                logWindow.title=Tr.phrase("Common","Import log wykonany ") + date.toUTCString();
                logWindow.open();
                logWindow.loadContent(reqString);

这是ContentWindow.mxml的代码：

<s:Window

preinitialize="init()"
xmlns:mx="http://www.adobe.com/2006/mxml"
xmlns:s="library://ns.adobe.com/flex/spark"
width="{_width}" height="{height}" backgroundColor="#FFFFFF"

            var loader:URLLoader = new URLLoader();
            loader.addEventListener(Event.COMPLETE, onTextLoaded);
            loader.load(urlReq);

            _text=e.target.data;
            _menuItem.data=_text;

        //  logText.text=_text;

            _menuItem.addEventListener(MouseEvent.CLICK,saveTextContent);
        }

        private function saveTextContent(e:Event):void
        {
            var file:FileReference = new FileReference();

当前结果是创建了窗口，但其中没有显示任何内容。当我调试时，我发现其中包含的元素根本没有初始化（这就是为什么“ logText.text = _text被注释掉）的原因，这就是我试图至少显示标签的原因。我也尝试使用此标签.stage.addChild（oneOfTheComponentsHere），但它也没有做任何更改。任何建议将不胜感激，在此先感谢。

在<s：window>标记内显示内容的问题
