Adobe Flash Builder（flex4）：addChild（）在此类中不可用。 [英] Adobe Flash Builder (flex4): addChild() is not available in this class.

问题描述

  var ldr：Loader =新的Loader（）; 
 ldr.load（new URLRequest（file：// path / to / fileswf））; 
 ldr.contentLoaderInfo.addEventListener（Event.INIT，loaded）; 
 function loaded（evt：Event）：void {addChild（ldr）; } 
  

我收到错误：

错误：addChild（）在此类中不可用。而是使用addElement（）或修改皮肤（如果有）。在spark.components.supportClasses :: SkinnableComponent / addChild（）中添加

[E：\dev\gumbo_beta2\frameworks\在主/ private：init / loaded（）[C：\ Documents and Settings \\ \\ ufk\\Adobe Flash Builder Beta 2 \xpogames-toolkit-test\src\main.mxml：22]

如果将 addChild（）更改为 addElement（），则会收到以下编译错误：

1067：类型为flash.display的值的隐式强制：将Loader转换为不相关的类型mx.core：IVisualElement。

任何想法如何解决这个问题？
在Flash Builder 4完整版中，没有任何this.rawChildren。

最好的解决方案解决问题的方法是将每个所需的类转换为一个flex组件，并在您的flex应用程序中使用它：
$ b

1. 下载并安装flex组件套件
   http：// www。 adobe.com/cfusion/entitlement/index.cfm?e=flex_skins




2. 创建影片剪辑

b $ b

3. 转换为flex组件




4. 将相关函数添加到此类中







附加到即将转换为flex组件的动画片段的类的框架：

  package {
 import mx.flash.UIMovieC唇; 
 import flash.text.TextField; 
 import flash.events.Event; 
 import flash.events.MouseEvent; 
 public dynamic class challenge_screen extends UIMovieClip {
 
 public function challenge_screen（）{
 super（）; 
} 
} 
} 
  




I want to load an swf into a flex 4 application in order to use its classes.

var ldr:Loader=new Loader();
ldr.load(new URLRequest("file://path/to/fileswf"));
ldr.contentLoaderInfo.addEventListener(Event.INIT, loaded);
function loaded(evt:Event):void { addChild(ldr); }

I receive the error:

Error: addChild() is not available in this class. Instead, use addElement() or modify the skin, if you have one.
at spark.components.supportClasses::SkinnableComponent/addChild()[E:\dev\gumbo_beta2\frameworks\projects\spark\src\spark\components\supportClasses\SkinnableComponent.as:966]
at main/private:init/loaded()[C:\Documents and Settings\ufk\Adobe Flash Builder Beta 2\xpogames-toolkit-test\src\main.mxml:22]

If I change addChild() to addElement(), I receive the following compilation error:

1067: Implicit coercion of a value of type flash.display:Loader to an unrelated type mx.core:IVisualElement. main.mxml path/dir line 22 Flex Problem

Any ideas how to resolve this issue?

解决方案

well in flash builder 4 full version, there isn't any this.rawChildren.

The best approach to resolve the issue would be to convert each required class to a flex component and to use it on your flex application:

1. download and install flex component kit http://www.adobe.com/cfusion/entitlement/index.cfm?e=flex_skins

2. create a movie clip

3. convert to flex component

4. add the relevant functions to this class

a skeleton for a class that is attached to a movieclip that is about to be converted to a flex component:

package {
import mx.flash.UIMovieClip;
import flash.text.TextField;
import flash.events.Event;
import flash.events.MouseEvent;
public dynamic class challenge_screen extends UIMovieClip {

    public function challenge_screen() {
        super();
    }
}
}
