Question

我使用Flash CS4 Professional构建可拖动元素。但是，每当我输入我的代码时，我都会收到错误1131.有人可以告诉我我做错了什么吗？

stop();

class Scrollbar extends Sprite
{
    var value:Number;
    var padding:Number = 5;

    var _textField:TextField;
    var max:Number;
    var min:Number;
    function draggable()
    {
        min = bar_mc.y;
        max = bar_mc.height - Erhu_H3_btn.height;
        Erhu_H3_btn.addEventListener(MouseEvent.MOUSE_DOWN, dragHandle);
    }

    function dragHandle(event:MouseEvent):void
    {
        Erhu_H3_btn.startDrag(false, new Rectangle(0,min,0,max));
        stage.addEventListener(MouseEvent.MOUSE_UP, stopDragging);
    }

    function stopDragging(event:MouseEvent):void
    {
        Erhu_H3_btn.stopDrag();
        stage.removeEventListener(MouseEvent.MOUSE_UP, stopDragging);
    }

}

您应该将Scrollbar类的代码放在单独的.as文件中，然后您可以声明这样的实例：

import PackageName.Scrollbar;
stop();
var scrollbar:Scrollbar = new Scrollbar();

滚动条类位于＆＃34; PackageName \ Scrollbar.as＆＃34;：

package PackageName{
    import flash.display.Sprite;
    public class Scrollbar extends Sprite{
         var value:Number;
         //...
    }

}

错误1131：不能嵌套类
