【问题描述】：
我正在创建一个具有多个页面的 Tkinter 规划器应用程序。在开始页面，您可以在日历中输入日期，然后按“进入”按钮进入应用程序。
然后主页会在右上角显示日期。有没有办法让日期标签与蓝色横幅重叠，这样顶部就没有灰线？还需要放置日期，以便即使在调整窗口大小时它也保持在同一个位置，因此我使用了 pack 功能。但是，我认为pack功能不能与其他标签重叠。

您好，请提供一个可重现的最小示例 (stackoverflow.com/help/minimal-reproducible-example)。
-
但是我可以说，正如您所说，pack 函数不能与其他标签重叠，因此有两种可能的解决方案：1 - 在调整窗口大小或 2 时使用绑定方法使用 place 和 update de position - 您可以将蓝色横幅制作为框架，而不是带有两个标签的标签：一个用于日期（最初为空白），另一个用于标题。设置日期后，您只需更改日期标签文本
