尝试在AS3中扩展SimpleButton类时，收到以下编译时错误:

1017:找不到基类SimpleButton的定义

和代码:

package com.shakti.gameState{

import flash.display.SimpleButton.SimpleButton;

public class buttonTile extends SimpleButton {

    public var id:int;
    public var quizId:int;
    public var subjectId:int;
    public var points:int;
    public var questionTxt:String;
    public var order:int;
    public var option:Array;

    public function buttonTile(newId:int, newQuizId:int, newSubId:int, newPoints:int, qtxt:String, newOrder:int, newOption:Array) {
        this.id=newId;
        this.quizId=newQuizId;
        this.subjectId=newSubId;
        this.points=newPoints;
        this.questionTxt=qtxt;
        this.order=newOrder;
        this.option=newOption;
    }
}}

最佳答案

导入类(class)。

 import flash.display.SimpleButton
