<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="vertical"
verticalAlign="middle"
backgroundColor="white"
creationComplete="init();"> <mx:Script>
<![CDATA[
import mx.controls.Alert;
import mx.styles.StyleManager; private var alert:Alert;
private var alertCSS:CSSStyleDeclaration; private function init():void {
alertCSS = StyleManager.getStyleDeclaration("Alert");
} private function showAlert(color:Object):void {
alertCSS.setStyle("modalTransparencyColor", color);
alertCSS.setStyle("themeColor", color);
alert = Alert.show("The quick brown fox...");
}
