     < mx:Array  id ="arr"   />
     < mx:String  id ="str" > The quick brown fox jumped over the lazy dog. </ mx:String >

     < mx:ApplicationControlBar  dock ="true" >
         < mx:Label  text ="String:"   />
         < mx:TextInput  id ="textInput"  text ="{str}"   />

         < mx:Spacer  width ="100%"   />

         < mx:Label  text ="Number of installed fonts: {arr.length}"   />
     </ mx:ApplicationControlBar >

     < mx:DataGrid  id ="dataGrid"  dataProvider ="{arr}" >
         < mx:columns >
             < mx:DataGridColumn  dataField ="fontName"
                    width ="200"
                    itemRenderer ="mx.controls.Label"   />
             < mx:DataGridColumn  dataField ="fontStyle"   />
             < mx:DataGridColumn  dataField ="fontType"   />
         </ mx:columns >
     </ mx:DataGrid >

     < mx:Label  id ="lbl"
            text ="{textInput.text}"

            fontFamily ="{dataGrid.selectedItem.fontName}"

</ mx:Application >

 

效果：

如果修改上面的例子，并使用下面的代码嵌入一个字体，那么在表格中也会显示出来“Base02"字体：

< mx:Style >
    @font-face{
        src: url("./fonts/base02.ttf");
        fontFamily: "Base02";
    }
</ mx:Style >

如果把 enumerateFonts()方法的参数改为flase，那么只会列举出嵌入字体：

< mx:Script >
     <![CDATA[
        import flash.text.Font;

        private function init():void {
            arr = Font.enumerateFonts(false);
            arr.sortOn("fontName", Array.CASEINSENSITIVE);
        }
     ]]>
</ mx:Script >
