您有几个选项，我简化了代码，修复了拼写错误并删除了对未包含的对象的引用。正如您在下面的代码中所看到的，您可以一直到topLevelApplication，或者在这种情况下，只需引用您定义的id。

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
           xmlns:s="library://ns.adobe.com/flex/spark" 
           minWidth="955" minHeight="600" initialize="initApp(event)" >
<fx:Script>
    <![CDATA[
        import mx.core.FlexGlobals;
        import mx.events.FlexEvent;



        protected function initApp(event:FlexEvent):void
        {
            // Either from the top, if in another class, or ...
            var pnl:Panel = Panel(FlexGlobals.topLevelApplication.leftPanel);
            pnl.width = 500;
            // Directly, since we are in this context.
            leftPanel.width = 500;
        }

    ]]>
</fx:Script>
<fx:Declarations>
    <!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>

<s:Panel id="leftPanel">

</s:Panel>
</s:Application>

此示例在Flash Builder中运行。无论您的LeftPanel的实际内容如何，这都应该有效。
