<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white"
        creationComplete="init()">

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

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

    <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}"
            width="{dataGrid.width}"
            height="32"
            fontFamily="{dataGrid.selectedItem.fontName}"
            fontSize="16" />

</mx:Application>

 

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>
