<s:TextInput id= 
        "text1"? 
        x= 
        "190"? 
        y= 
        "93" 
        /> 
       
"text2"? 
        "142" 
        /> 
       
<s:Label x= 
        "147"? 
        "94"? 
        text= 
        "var1:" 
        /> 
       
"142"? 
        "var2:" 
        /> 
       
</s:Application> 
       
 
    

参数在Flex4的获取方式跟Flex3是不一样的：

Flex3:??var?params:Object?=?Application.application.parameters;?

Flex4:??var?params:Object?=?FlexGlobals.topLevelApplication.parameters;?
