Flex/AIR，如何将焦点设置在 UI 控件、按钮等上? [英] Flex / AIR, how to set focus on a UI Control, Button, etc?

问题描述

因此，我试图在应用启动时(或稍后基于某些事件)将焦点设置在特定按钮上，以便用户只需按回车键即可.但是，以下方法均无效.

So, I'm trying to set focus on a specific button when the app launches (or later based on certain events), so that the user can simply hit return to press the button. None of the following approaches work however.

<代码>受保护的函数 group1_creationCompleteHandler(event:FlexEvent):void
{
//btnBrowse.setFocus();
focusManager.setFocus(btnBrowse);
}

protected function group1_creationCompleteHandler(event:FlexEvent):void
{
//btnBrowse.setFocus();
focusManager.setFocus(btnBrowse);
}

推荐答案

尝试:

protected function group1_creationCompleteHandler(event:FlexEvent):void
{
  callLater(btnBrowse.setFocus);
}
