如何在Flash CS4 AS3中获得数字步进和滑块

Question

嗨，我正在为学校的课程工作，我想拥有一个页面，我的滑块反映了数字步进，反之亦然，但是每当我在线找到教程时，给我错误，其中最新的是1120：访问未定义的属性numericStepperevent。我不愿继续使用其余的草原，因为我不确定如何使它工作，但我需要在星期五之前完成此部分。任何帮助将不胜感激。

谢谢马特

您需要告诉编译器使用哪个类。目前，它不知道numericStepperevent是什么。

与其他导入一起添加顶部： import mx.events.NumericStepperEvent;

还建议更改写入 Event:SliderEvent的参数变量到小写event:SliderEvent，因为这可能会导致另一个编译器错误。
