How to load and apply CSS stylesheet at runtime in a Flex application?

Question

I would like to download CSS stylesheets from a URL and apply them to my Flex 3 application at runtime. Is it possible?

Answer 1

You cannot load an uncompiled CSS file into your Flex application at run time. You must compile it in SWF before downloading. - Adobe Flex 3 documents

You can load stylesheets (compiled) using the Style Manager.

Answer 2

css , TextField.

var loader:URLLoader = new URLLoader();
var req:URLRequest = new URLRequest("style.css");
loader.load(req);
loader.addEventListener(Event.COMPLETE, completeHandler);

private function completeHandler(e:Event):void 
{
  var css:StyleSheet = new StyleSheet();
  css.parseCSS(e.target.data);
  yourTextField.styleSheet = css;
}
