Python 中 Tkinter 的 Mac OS 的 wm_overridedirect 方法的替代方案

Question

我制作了一个 Tkinter 小部件，它本质上是一个 Combobox，其列表 1) 在打字期间可见，2) 在打字期间缩短，3) 允许箭头键/输入功能。我使用这两个帖子（first 和second）来找出一些功能。请参阅下面的课程代码和 MRE。

我的问题：我的 Search 小部件适用于 Windows，但不适用于 Mac OS，我相信这是因为 .wm_overrideredirect() 方法在 Mac OS 中的行为不同（至少对于大苏尔）与 Windows。我的预期功能是让TopLevel 小部件仅包含并显示Text 小部件而不接收焦点。下面的代码在 Windows 中实现了这一点，但在 Mac OS 中却没有。 Mac OS 的替代品是什么？换句话说，是否有任何替代方法可以让小部件扩展到root 之外？

在 Windows 10 上运行时单击条目小部件会执行以下操作：

在 Mac OS Big Sur 上运行时单击条目小部件会执行以下操作：

谢谢！

看起来有些人可以让它在 MacOS Big Sur 上运行。一定是我机器的问题。谢谢大家的帮助。
