为什么这个 Flex App 不绘制一个简单的矩形?

问题描述

代码很简单，我的意图应该很明确.我仍然可以让它工作:

the code is straightforward and my Intention should be clear. Still i can get this to work:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" 
               xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"
               creationComplete="application1_creationCompleteHandler(event)">
    <fx:Script>
        <![CDATA[
            import mx.events.FlexEvent;

            protected function application1_creationCompleteHandler(event:FlexEvent):void
            {
                var mySprite:Sprite = new Sprite();
                mySprite.graphics.lineStyle(1,0x0000FF,1.0);
                mySprite.graphics.drawRect(0,0,200,50);
                this.addChild(mySprite);
            }

        ]]>
    </fx:Script>
    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>


</s:Application>

就这么简单的一个问题，给我带来了一些麻烦！你能帮忙吗?

推荐答案

试试这个

var x:SpriteVisualElement = new SpriteVisualElement();              
var mySprite:Sprite = new Sprite();
mySprite.graphics.lineStyle(1,0x0000FF,1.0);
mySprite.graphics.drawRect(0,0,200,50);
x.addChild(mySprite);       
this.addElement(x);
