在flex3的button內文字增加文字陰影

上面的連結是教學我們如何在label上增加文字濾鏡
那我們要如何在按鈕上增加文字濾鏡呢?
主要就是要在按鈕生成後抓取裡面的文字元件然後增加濾鏡效果

btn.addEventListener(FlexEvent.CREATION_COMPLETE,addFilter);

1	btn.addEventListener(FlexEvent.CREATION_COMPLETE,addFilter);

抓取button的label的方式是下面這行

((e.target as Button).getChildAt(1) as TextField).filters = myFilters;

1	((e.target as Button).getChildAt(1) as TextField).filters = myFilters;

所以整個函數可能如下

import flash.filters.*;

//增加文字陰影
private function addFilter(e:Event):void{
var f:DropShadowFilter = new DropShadowFilter(3,30,0x000000,.8);
var myFilters:Array = new Array();
myFilters.push(f);
((e.target as Button).getChildAt(1) as TextField).filters = myFilters;
}

import flash.filters.*;

//增加文字陰影

private function addFilter(e:Event):void{

var f:DropShadowFilter = new DropShadowFilter(3,30,0x000000,.8);

var myFilters:Array = new Array();

myFilters.push(f);

((e.target as Button).getChildAt(1) as TextField).filters = myFilters;

}
