Flex 一些常用的语句

导读：获取顶层的应用程序: Application.application 自从4.0以后使用: FlexGlobals.topLevelApplication 持续更新中... 2.设置绑定图片样式: CSS样式 ? selectedUpSkin:Embed('/image/fullScreen.png'); ? upSkin:Embed('/image/fullScreen.png'); ? selectedOver
  1. 获取顶层的应用程序:

Application.application

自从4.0以后使用:

FlexGlobals.topLevelApplication

持续更新中...

2.设置绑定图片样式:

CSS样式
? selectedUpSkin:Embed('/image/fullScreen.png');
? upSkin:Embed('/image/fullScreen.png');
? selectedOverSkin:Embed('/image/fullScreen.png');
? selectedDownSkin:Embed('/image/fullScreen.png');
? downSkin:Embed('/image/fullScreen.png');
? overSkin:Embed('/image/fullScreenOn.png');
? disabledSkin:Embed('/image/fullScreen.png');
其实有的按钮可以直接是一张图片，那样更简单

3.无边框的button可以使用:LinkButton,不可用的时候得样式为:disabledIcon

举例:

<mx:LinkButton width="30" height="25" click="doMeasureLine()"
?? ??? ??? ??? ??? ??? ??? icon="{Constants.i_measure}" toolTip="测量距离"/>???
4.如何设置ToggleButtonBar工具栏的button的样式?

涉及到的样式有:

buttonStyleName="toolButton"? firstButtonStyleName="toolButton" lastButtonStyleName="toolButton"

具体的样式设置为:spark控件设置其皮肤样式,可以是系统自带的,也可以是自定义的

.toolButton
{
?? ?skin:ClassReference("com.gis.skins.ToggleLinkButtonSkin");

}

自定义的皮肤,当选中某个按钮时,样式是有底色的样式,用来标记选中状态

package com.gis.skins
{
	
	import mx.skins.halo.LinkButtonSkin; 
	
	public class ToggleLinkButtonSkin extends LinkButtonSkin { 
		public function ToggleLinkButtonSkin() { 
			super(); 
		} 
		
		override protected function updateDisplayList(w:Number,h:Number):void { 
			super.updateDisplayList(w,h); 
			
			var cornerRadius:Number = getStyle("cornerRadius"); 
			var rollOverColor:uint = getStyle("rollOverColor"); 
			var selectionColor:uint = getStyle("selectionColor"); 
			
			graphics.clear(); 
			
			switch (name) { 
				case "upSkin": 
					// Draw invisible shape so we have a hit area. 
					drawRoundRect( 
						0,w,h,cornerRadius,0); 
					break; 
				
				case "selectedUpSkin": 
				case "selectedOverSkin": 
				case "overSkin": 
					drawRoundRect( 
						0,rollOverColor,1); 
					break; 
				
				case "selectedDownSkin": 
				case "downSkin": 
					drawRoundRect( 
						0,selectionColor,1); 
					break; 
				
				case "selectedDisabledSkin": 
				case "disabledSkin": 
					// Draw invisible shape so we have a hit area. 
					drawRoundRect( 
						0,0); 
					break; 
			} 
		} 
	} 

}
当然,如果仅仅需要无边框的按钮样式,则只需要: 

skin:ClassReference("mx.skins.ProgrammaticSkin");

这样的样式,选中状态和原来是一样的,所以紫荆衣扩展了一下

发现一个问题:

使用HttpService，提供get方法返回xml数据的时候，Flex总是显示旧的数据。解决方法是在你请求的Servlet地址添加一个参数（参数名随便起，我用random）,而且请求的参数必须每一次都不一样（可以通过当前时间或者UUID实现），例如：http://192.168.2.111:8080/UserController.do?servlet=getAll&random=sdfsdfs
