Once a month this issue comes up. Because there is no function olverloading in AS3, we can't change the parameter list of addChild, but basically, frameworks have rules and the rules for Flex are:
Navigator children must be Containers Container children must be IUIComponents UIComponent children can be anything. I swear I replied to this thread two days ago, but answer is to instantiate a UIComponent and addChild your sprite to it. ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Blake Barrett Sent: Wednesday, March 05, 2008 12:48 PM To: [email protected] Subject: RE: [flexcoders] Re: How can I add Sprite / MovieClip to stage without error of not IUIComponent? I've been experiencing similar issues from a slightly different direction. I have various things in a swf file authored in Flash CS3 and I have been needing to pull them out of that swf and add them to the stage in a Flex 2.0.1 app. What I ended up having to do is actually create an instance of an <mx:SWFLoader/> in the MXML and address everything through that. I was met with mixed results trying to dynamically add a new SWFLoader(), but I was able to do what I needed to do using the <mx:SWFLoader/> (since it is some sort of Flex object that loads an AVM2Movie SWF as its .content property once it is done loading). It's kinda ghetto, but maybe you could look into the <mx:Sprite/> object. Maybe create one of those declaratively, give it an ID and just manipulate that.

Regarding Flex 3, addChild with a Sprite instance as argument does not work in contrast to what the Flex 3 documentation tells us. One of the examples taken from the Flex 3 language reference: public function SpriteExample() { var child:Sprite = new Sprite(); child.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler); child.addEventListener(MouseEvent.MOUSE_UP, mouseUpHandler); draw(child); addChild(child); } The method signature is public function addChild(child:DisplayObject):DisplayObject Clearly the addChild should accept any instance of DisplayObject which Sprite clearly is. It worries me deeply that a type cast is performed in the private override mx_internal function addingChild(child:DisplayObject):void // Throw an RTE if child is not an IUIComponent. var uiChild:IUIComponent = IUIComponent(child); It worries me even more that this slipped through QA.
