如何将BasicView添加到Flex UIComponent中。

原文转载如下：

Adding a BasicView to a Flex UIComponent

?

While I would always encourage to separate your code into separate classes to follow best OOP practices,the example below will “get the job done”.

Since the Flex framework is based off UIComponents and you can’t directly add Sprites (or BasicViews) to a UIComponent,you have to dig into the UIComponents rawChildren (meaning Sprites) to add Papervision3D.

??? height="480"
??? xmlns:mx="http://www.adobe.com/2006/mxml"

??? applicationComplete="applicationComplete()">
??? <mx:Script>
??? ??? <![CDATA[
/*??? ??? ??? There are two similar methods:

//??? ??? ??? use namespace mx_internal; //method #2

??? ??? ??? import org.papervision3d.objects.primitives.Sphere;
??? ??? ??? import org.papervision3d.view.BasicView;
??? ??? ??? private function applicationComplete():void
??? ??? ??? {
??? ??? ??? ??? var basicView:BasicView = new BasicView();
??? ??? ??? ??? var sphere:Sphere = new Sphere();
??? ??? ??? ??? basicView.scene.addChild(sphere);
??? ??? ??? ??? basicView.startRendering();
??? ??? ??? ??? pv3dPanel.rawChildren.addChild(basicView); //method #1
//??? ??? ??? ??? pv3dPanel.$addChild(basicView); //method #2
??? ??? ??? }
??? ??? ]]>
??? </mx:Script>
??? <mx:Panel id="pv3dPanel" title="Papervision3D Panel" width="640" height="480"/>
</mx:Application>

============================= //add by sing

以上代码是flex3下可以正常使用，在flex4下要做如下修改：

例如要将basicView添加到Group中。代码如下：

?

var uicomponent: UIComponent = new UIComponent(); uicomponent.addChild(basicView); sGroup.addElementAt(uicomponent,0);
