使ButtonBar的按钮字体显示描边效果

ButtonBar的按钮可以重写一下里面创建按钮的函数，达到修改按钮的效果

override protected function createNavItem(label:String, icon:Class=null):IFlexDisplayObject{    var _btn:Button = Button(super.createNavItem(label,icon));    var _textField:TextField = _btn.mx_internal::getTextField();    _textField.filters = myGlowFilter;    return  _btn; }      private var _defaltColor:uint=0x000000;   private var defaultFilters:Array;    private function get myGlowFilter():Array   {    if( !defaultFilters )    {     var defaultGF:GlowFilter = new GlowFilter(_defaltColor,1,2,2,50,1,false,false);     defaultFilters = new Array();     defaultFilters.push( defaultGF );    }    return defaultFilters;   }
