As3导入的自定义类在主阶段不会访问组件。-As3importedcustomclasswon'taccesscomponentsatmainstage

I have this situation. I was building all in code, but it's a little painful, so I made a interface with components using the Flash drawing capabilities.

我有这种情况。我构建了所有代码，但是有点痛苦，所以我使用Flash绘图功能创建了一个与组件的接口。

I got a main class, as usual, with the interface in a MovieClip instance called "AreaEdit". In my custom class "EditorHTML" there is a Sprite:

像往常一样，我在一个名为“AreaEdit”的MovieClip实例中获得了一个主类。在我的自定义类“编辑器”中有一个精灵:

private var dTela:Sprite;

So the constructor is like this:

构造函数是这样的

public function EditorHTML(instEdit) {
    this.Parags = new Array();
    this.dTela = instEdit;
    trace("dTela: "+this.dTela.width+" x "+this.dTela.height);
}

At the main class:

在主类:

Escrit = new EditorHTML(AreaEdit);

So trace displays the dimensions of the box, as expected. However, at the custom class, if I try to access an instance inside like this:

因此，trace将按预期显示该框的大小。但是，在自定义类中，如果我尝试访问这样的实例:

this.dTela.cxEdit.addEventListener(Event.CHANGE, atualizar);

An error is returned: /Library/WebServer/Documents/as3/bibliotecas_externas/com/gustavopi/txt/EditorHTML.as, Line 49 1119: Access of possibly undefined property cxEdit through a reference with static type flash.display:Sprite.

返回一个错误:/Library/WebServer/Documents/as3/bibliotecas_externas/ com/gustavopi/txt/editorhtml。如，第491119行:使用静态类型flash的引用访问可能未定义的属性cxEdit。显示:Sprite。

I did a test and the same instance "cxEdit" is available in main class. So it seams the components instances are not available for a custom class. How do I solve this?

我做了一个测试，同样的实例“cxEdit”在主类中可用。因此，对于自定义类来说，组件实例是不可用的。怎么解呢?

2 个解决方案

  Sprite( Sprite(this.dTela).getChildByName("cxEdit")).addEventListener(Event.CHANGE, atualizar);

var cxEdit:TextArea = TextArea(Sprite(this.dTela).getChildByName("cxEdit"));
cxEdit.addEventListener(Event.CHANGE, atualizar);
