Python PBI.pybusynfo保持在顶部

我有下面的代码，它通过applescript打开Quicktime，并对文件进行处理，这需要一些时间，不能被打扰。我想要一个对话框窗口在所有其他窗口的顶部打开，不管它必须保持在顶部，它只是说“正在处理文件，请稍候”。这段代码可以工作，但只要quicktime通过applescript打开，PBI.pybusynfo就会消失。你知道我该怎么做吗

您的问题似乎缺少启动AppleScript的调用（看起来您忘了将jesFile方法添加到示例代码中）。我只能对你的代码推测太多，而这不在发布的示例中。。。但我猜您对do processing的调用不是阻塞调用，因此您需要将其设置为阻塞调用，或者将busy保存到一个类变量，在非阻塞进程调用返回时删除该类变量（希望您可以绑定一个回调函数）
