【问题描述】：
设置
我有两个 SWF，A 和 B。 A 是 B 的简单预加载器，它作为子级添加到 A。 B 使用我编写的自定义类来创建照片库，我将其称为 C。这是我第一次尝试自己上课，所以请多多包涵：/
问题
当我测试 A 时，我收到此错误：
ReferenceError: Error #1065: Variable ScrollEvent is not defined.
at MethodInfo-4757()
at MethodInfo-4748()
现在有几个原因导致这特别令人困惑。首先，在C（后面的代码）中定义ScrollEvent。其次， B 在库中有一个 UIScrollBar 和 ProgressBar （C 也使用）组件，但是当我添加一个 ScrollBar 和 ProgressBar 组件时A 的库错误消失了，但生成的 SWF 使用的是 A 中的组件，而不是 中的自定义皮肤组件乙。这可能有一个明显的答案，但我对这个很困惑，所以任何帮助都将不胜感激！
B - A 加载的主 SWF，它创建 C 的实例。该项目将其称为 claudia.as
因为太长，我不能把所有的代码都贴出来，所以这里是在B中创建一个C的实例：
public function pg3_setup():void
{
var address:String = "flash_scripts/photo_gallery.xml";
var gallery:claudeGallery = new claudeGallery(address,bg.width - p_pad_left - p_pad_right,bg.height - p_pad_top - p_pad_bottom,true,des_array[2],init_array);
gallery.addEventListener("SETUP_COMPLETE",g_complete);
function g_complete(e:Event)
{
pg_array[des_array.indexOf("gallery")].addChild(gallery);
setup_counter_add();
}
}
C - 我创建画廊精灵的自定义类，由 B 调用。它的真名是claudeGallery.as
