[置顶] Flex4/Air之隐藏状态栏，标题栏，最大，最小，半闭按钮，窗体可拖拽效果

在进行前台显示的过程中，也即桌面应用程序开发过程中，我个有时候会用到一些效果，比如只要一个浮动的无状态栏，标题栏，最大，最小，半闭按钮，并且窗体还可以拖动的效果，为了实现这个效果，我们就要对其进行一系列处理，

1.首先在在家***-app.xml文件中，大概54左右加入，即在<initialWindow>标签内加入如下代码：

 <!-- The type of system chrome to use (either "standard" or "none"). Optional. Default standard. -->
  <systemChrome>none</systemChrome>
  <!-- Whether the window is transparent. Only applicable when systemChrome is none. Optional. Default false. -->
  <transparent>true</transparent>
		

上面的代码用来隐藏标题栏，最大，最小，半闭按钮，

2.接下来在<s:WindowApplication>中加入

<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009" 
					   xmlns:s="library://ns.adobe.com/flex/spark" 
					   xmlns:mx="library://ns.adobe.com/flex/mx"
					   width="1558"
					   height="740"
					   showStatusBar="false"
			。。。。。。。。。。。。。。。。。。。。。。。
					   >

3.实现置顶和拖动效果，关键代码如下所示：

		this.stage.nativeWindow.startMove();
	        this.stage.nativeWindow.alwaysInFront=true;

4.在这里，我用了一个定时器做特效效果，主要代码如下：

		public var glowTimer:Timer=new Timer(5000);
			
			
			protected function application1_initializeHandler(event:FlexEvent):void
			{
				// TODO Auto-generated method stub
				glowTimer.addEventListener(TimerEvent.TIMER,GlowTimerFunc);
				glowTimer.start();
				
				
			}
			
			public function GlowTimerFunc(event:TimerEvent):void{
				Glow1.target=welcomeLeader;
				Glow1.play();
			}

5.这里附上所示代码，如下所示：

<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009" 
					   xmlns:s="library://ns.adobe.com/flex/spark" 
					   xmlns:mx="library://ns.adobe.com/flex/mx"
					   width="1558"
					   height="740"
					   backgroundColor="#00244f"
					   showStatusBar="false"
					   backgroundAlpha="0"
					  creationComplete="windowedapplication1_creationCompleteHandler(event);"
				      initialize="application1_initializeHandler(event);"
					   >
	<fx:Declarations>
		<!-- 将非可视元素（例如服务、值对象）放在此处 -->
		<mx:Glow id="Glow1"  alphaFrom="0" alphaTo="1" blurXFrom="1"
				 blurXTo="100" blurYFrom="1" blurYTo="100" duration="5000" 
				 color="#00244f"  inner="true" target="{welcomeLeader}"/>
	</fx:Declarations>
	
	
	<fx:Script>
		<![CDATA[
			import mx.events.FlexEvent;
			import flash.display.NativeWindow;
			
			public var glowTimer:Timer=new Timer(5000);
			
			
			protected function application1_initializeHandler(event:FlexEvent):void
			{
				// TODO Auto-generated method stub
				glowTimer.addEventListener(TimerEvent.TIMER,GlowTimerFunc);
				glowTimer.start();
				
				
			}
			
			public function GlowTimerFunc(event:TimerEvent):void{
				Glow1.target=welcomeLeader;
				Glow1.play();
			}
			
			protected function windowedapplication1_creationCompleteHandler(event:FlexEvent):void
			{
				
			//	this.nativeWindow.startMove();
				
			//	this.stage.nativeWindow.alwaysInFront=false;
				/**stage.nativeWindow
				var window:NativeWindow = stage.nativeWindow;
				window.alwaysInFront = true; //alwaysInFront 如果为 true，那么就表示这个AIR窗体始终置前！
				**/
//				window.alwaysInFront = true;
		
				// TODO Auto-generated method stub
				//http://hi.baidu.com/taotao5453/blog/item/29d97c8dcc768708b31bba93.html
				//stage.window.alwaysInFront=!stage.window.alwaysInFront; 
				//stage.window.startMove(); 
				
	
				
			}
			
			
			import mx.graphics.ImageSnapshot; 
			import mx.controls.Image; 
			import mx.core.UIComponent; 
			
			public var uiComponent:Object; 
			public var targetImage:Image; 
			public var Ax:int = 0; 
			public var Ay:int = 0; 
			public function mouseDown(event:MouseEvent):void{ 
		
				this.stage.nativeWindow.startMove();
				this.stage.nativeWindow.alwaysInFront=true;
			} 

			
			
		]]>
	</fx:Script>
	
	<!--  欢迎词可配置, 添    -->
	<s:Label id="welcomeLeader" x="4" y="9" width="1554" height="160" alpha="0.9"
			 backgroundColor="#00244f" color="yellow" fontFamily="中易黑体" fontSize="45"
			 fontWeight="bold" text="   热烈欢迎*****************************一行莅临*********指导工作" textAlign="left"
			 verticalAlign="middle"
			 mouseDown="mouseDown(event)" 
			 
			 />
</s:WindowedApplication>

特效如下所示：
