Flex 3: Embedding MovieClip Symbol to Image Control programmatically
-

Question
I've reviewed all the documentation and Google results surrounding this and I think I have everything setup correctly. My problem is that the symbol is not appearing in my app. I have a MovieClip symbol that I've embedded to my Flex Component. I need to create a new Image control for each item from my dataProvider and assign this embedded symbol as the Image's source. I thought it was simple but apparently not. Here's a stub of the code:
[Embed(source="../assets/assetLib.swf", symbol="StarMC")]
private var StarClass:Class;
protected function rebuildChildren():void {
iterator.seek( CursorBookmark.FIRST );
while ( !iterator.afterLast ) {
child = new Image();
var asset:MovieClipAsset = new StarClass() as MovieClipAsset;
(child as Image).source = asset;
}
}
I know the child is being created because I can draw a shape and and that appears. Am I doing something wrong? Thank you!
Solution
You should be able to simply set child.source to StarClass:
child = new Image();
child.source = StarClass;
See the MovieClipAsset Language Reference for more details:
you rarely need to create MovieClipAsset instances yourself because image-related properties and styles can be set to an image-producing class, and components will create instances as necessary. For example, to set the application background to this animation, you can simply write the following:
<mx:Application backgroundImage="{backgroundAnimationClass}"/>
