我正在使用
基本上,我想要将这个日历小部件输入到我的Tkinter应用程序中,这样就可以正常工作,没有问题。
我希望克服的问题是:
ttkcalendar.py
,可以在此链接中找到:链接
我已经改编它以在Python 3.3
中使用。基本上,我想要将这个日历小部件输入到我的Tkinter应用程序中,这样就可以正常工作,没有问题。
我希望克服的问题是:
- 如何更改日历(月份、天数和日期)的字体大小 - 完成
- 如何更改所选日期使其变为
粗体
。 - 完成 - 如何更改
treeview
中行的高度,因为先前尝试中字体大小可以增加,但是行高度不会随字体大小而增加。 - 仍在等待帮助

我如何更改Treeview
的relief
?
style = ttk.Style(root)
style.configure('Treeview', rowheight=40)
但是这会改变所有树形视图的行高,而不是我想要的那个树形视图。我已经尝试更改root
,但没有成功,你能帮我解决这个问题吗? - Aleksandar Beat
