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

我想将 swf 加载到 flex 4 应用程序中以使用其类.

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); }

我收到错误:

错误:addChild() 在此类中不可用.相反，使用 addElement() 或修改皮肤(如果有).
在 spark.components.supportClasses::SkinnableComponent/addChild()[E:\dev\gumbo_beta2\frameworks\projects\spark\src\spark\components\supportClasses\SkinnableComponent.as:966]
在 main/private:init/loaded()[C:\Documents and Settings\ufk\Adobe Flash Builder Beta 2\xpogames-toolkit-test\src\main.mxml:22]

Error: addChild() is not available in this class. Instead, use addElement() or modify the skin, if you have one.

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

如果我将 addChild() 更改为 addElement()，我会收到以下编译错误:

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

1067:将 flash.display:Loader 类型的值隐式强制转换为不相关的 mx.core:IVisualElement 类型.main.mxml 路径/目录第 22 行 Flex 问题

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

任何想法如何解决这个问题?

Any ideas how to resolve this issue?

推荐答案

在 flash builder 4 完整版中，没有任何 this.rawChildren.

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

解决该问题的最佳方法是将每个必需的类转换为 flex 组件并在您的 flex 应用程序中使用它:

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

创建影片剪辑

转换为弹性组件

给这个类添加相关函数

附加到即将转换为 flex 组件的影片剪辑的类的骨架:

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();
    }
}
}
