Question

我有下面的代码，通过applescript打开Quicktime并对文件进行处理，这需要一段时间，不能被打扰。我想要一个对话窗口打开其他所有内容，无论它必须保持在最顶层，只是说“处理文件，请稍候”。此代码有效，但只要quicktime通过applescript打开，PBI.PyBusyInfo就会消失。知道我怎么能这样做吗？

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）。我只能推测你的代码不是在发布的例子中...但我的猜测是你的处理呼叫不是阻塞呼叫，所以你需要让它成为阻塞呼叫，或者保存忙到非阻塞进程调用返回时删除的类变量（希望您可以在发生这种情况时绑定回调函数）。

Python PBI.PyBusyInfo保持领先
