importing flash library symbol into flex - apache-flex

Question

I am embedding a flash file in my flex file and then trying to add it to the stage. IU try addChild to a canvas element and to a container element, but it keeps giving me the error, the symbol "myBtn" is cannot be converted to a IUIcomponent.
I understand that I need to place everything inside some sort of component, but what is the proper way to do this in flex?

Answer 1

Adding to rawChildren isn't the way to go here. Containers ignore rawChildren when doing things such as layout, measurement, etc.
Instead, simply wrap it in a UIComponent:
[Embed(source="...")]
public var someSwf:Class;
public function addSwf():void
{
var swf:Sprite = new someSwf();
var wrapper:UIComponent = new UIComponent();
wrapper.addChild(swf);
this.addChild(wrapper);
}

Answer 2

Look here for info on Embedding swf files and embedding swf symbols.

Answer 3

I figured it out thanks to this post: http://craiggrummitt.blogspot.com/2007/11/how-to-add-children-in-flex.html
you use something called rawChildren. so I would do myComponent.rawChildren.addChild('mymc');

Here you can downlod a complement to conver a symbol into a flex component from Flash
www.adobe.com/go/flex_ck_en
You can add all your move into a symbol then convert to flex component
Select the symbol from the libary then go to:
Commands > Convert Symbol to Flex Component
then import the swc resultant in flex
finally add the elemento into flex:
public var swfImported:NameOfTheSymbol=new NameOfTheSymbol();
private function init():void{
stage.addChild(swfImported);
}
