利用StyleManager和setStyle()事件设定Flex中Alert的风格

Mar 02

接下来的例子展示了如何利用静态的StyleManager.getStyleDeclaration()事件和 StyleManager.getStyleDeclaration() 事件，来设定Flex中Alert的风格。

下面是代码：

<?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"
themeColor="yellow"
click="showAlert('yellow');" />
<mx:Button label="Green"
themeColor="haloGreen"
click="showAlert('haloGreen');" />
<mx:Button label="Blue"
themeColor="haloBlue"
click="showAlert('haloBlue');" />
</mx:ApplicationControlBar>
</mx:Application>

执行效果：
