推荐答案

为了配合 J_A_X 的回答，如果您试图在应用程序首次加载时将焦点设置在组件上，您还需要 使用一些 javascript 将焦点设置在您的SWF.

To go along with J_A_X's answer, if you're trying to set focus on a component when the application first loads, you'll also need to use some javascript to set the focus on your SWF.

这是那篇文章中的示例代码:

Here's the sample code from that article:

Javascript:

<script type="text/javascript">
function onFlexInitialized()
{
    //alert("onFlexInitialized");

    <!-- Force the browser to set flex app with focus -->
    document.getElementById("${application}").focus();
}
</script>

ActionScript:

/**
 * Constructor.
 */
public function AppController()
{
    FlexGlobals.topLevelApplication.addEventListener(FlexEvent.APPLICATION_COMPLETE, onAppComplete); // Flex 4
        //Application.application.addEventListener(FlexEvent.APPLICATION_COMPLETE, onAppComplete); // Flex 3
}

/**
 * Handles the application complete event.
 */
protected function onAppComplete(e:FlexEvent):void
{
    FlexGlobals.topLevelApplication.removeEventListener(FlexEvent.APPLICATION_COMPLETE, onAppComplete); // Flex 4
        //Application.application.removeEventListener(FlexEvent.APPLICATION_COMPLETE, onAppComplete); // Flex 3

    if(ExternalInterface.available)
    {
        ExternalInterface.call("onFlexInitialized");
    }
}
