所以我想我知道我的问题是什么，但我似乎无法弄清楚如何解决它。我对wxPython比较陌生。我正在将终端脚本中的一些功能移动到GUI，似乎无法正确使用它。我使用anaconda进行python发布，并为GUI添加了wxPython。我希望用户能够将文件拖放到文本控件中，然后将文件内容导入到数据框中以便使用pandas进行分析。到目前为止一切都很开心。除了程序不会退出的事实。我认为这与我如何定义窗口和框架有关。我已从脚本中删除了大量功能，以帮助简化操作。请让我知道我错过了什么。

问题是您只创建一个MyFileDropTarget类的实例，然后将该同一个对象分配给多个小部件。看起来您需要为每个小部件创建一个放置目标实例。我稍微重构了你的代码，但这是一种方法：
