我正在通过 tkcalendar 创建一个班次表。
我想让选定的日期显示自己的时间表，如图所示。
是否可以通过 tkcalendar 提供的任何方法来实现这一点？或者我能做到这一点的唯一方法是从零创建一个自定义日历？我浏览了文档，但几乎找不到有用的东西。
注意：我不想要工具提示（弹出文本）

tkcalendar 的方法不可能在日历中的日期编号下方显示文本。但是，您不必从头开始，您可以创建一个Agenda继承自Calendar并仅重写显示事件的方法以将它们放在当天的标签中而不是弹出窗口中的类。
准确地说，需要修改 3 个方法：和_display_days_without_othermonthdays()，见下面的代码。代码可能看起来很长，但与 tkcalendar 中的原始版本相比，我实际上只修改了每种方法中的几行代码。_display_days_with_othermonthdays()_show_event()
