在Flex中使用StyleMaager类和setStyle()方法给Alert组件设置样式

实例演示了怎样利用 StyleManager.getStyleDeclaration() 方法和 setStyle() 给一个 Flex Alert组件设置样式

代码：

<?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...");
}

</mx:Script>

<mx:ApplicationControlBar dock="true">
<mx:Button label="Red"
themeColor="red"
click="showAlert('red');" />
<mx:Button label="Orange"
themeColor="haloOrange"
click="showAlert('haloOrange');" />
<mx:Button label="Yellow"

click="showAlert('yellow');" />
<mx:Button label="Green"
themeColor="haloGreen"
