Actionscript 3 如何使数字步进器和滑块在Flash CS4 AS3中协同工作

嗨，我正在为学校做一个课程作业，我想有一个页面，其中我有反映数字步进器的滑块，反之亦然。然而，每当我在网上找到教程时，它总是给我错误，最近的错误是1120：访问未定义属性NumericStepperEvent。我很犹豫是否继续使用其余的步进机，因为我不确定如何让它工作，但我需要在周五之前完成这一部分。任何帮助都将不胜感激

谢谢你，马特

}您需要告诉编译器要使用哪些类。目前它还不知道NumericStepperEvent是什么

在顶部添加其他导入添加：import mx.events.numericsteppervent

---

另外，我建议将参数变量writed Event:SliderEvent更改为小写Event:SliderEvent，因为这可能会导致另一个编译器错误。

好的，所以我这样做了，但现在我得到1172:definition fl.events.numericsteppervent找不到这是我的flash副本的问题吗？@Mattyhammers我的错误，它应该是mx.events.NumericStepperEvent，答案已更改。
