Question

i have a problem using AS3 – Flash CS3 gives me this Error message: Error #1065: Variable addChild is not defined.

Any ideas what’s wrong?

This is my code:

package coa.application{     import flash.display.SimpleButton;     import flash.text.TextField;     import flash.text.TextFieldType;      public class Tab extends SimpleButton {          public var menuType:String;          public function Tab(tabText:String, menuType:String) {             this.menuType=menuType;             var mytext:TextField=createTextField(0,0,200,20);             mytext.text=tabText;         }         private function createTextField(x:Number, y:Number, width:Number, height:Number):TextField {             var result:TextField = new TextField();             result.x=x;             result.y=y;             result.width=width;             result.height=height;             addChild(result);             return result;         }     }     }

It’s because SimpleButton does not inherit from DisplayObjectContainer but from InteractiveObject.

addChild is a method from DisplayObjectContainer. SimpleButton contains 3 displayobject for the 3 states and the hittest object, they are named upState, overState, downState and hitTestState.

So you should be able to set one of them.

//addChild(result); upState = result; 

You could just add a DisplayObjectContainer (like a Sprite) to the states and then add the TextField there instead, in case you want to add more graphics to the states.

upState = new Sprite(); upState.addChild(new MyButtonBackground()); //Make this class. upState.addChild(result);
