What is this line and How to remove the lines that appear automatically when creating a menu:

推荐答案

使用 tearoff=0.来自 NM 技术 Tkinter 参考:

撕掉

通常情况下，一个菜单可以被撕掉:选择列表中的第一个位置(位置 0)被撕掉元素占据，额外的选择从位置 1 开始添加.如果你设置了 撕下=0，菜单将没有撕下功能，并且从位置0开始添加选项.

Normally, a menu can be torn off: the first position (position 0) in the list of choices is occupied by the tear-off element, and the additional choices are added starting at position 1. If you set tearoff=0, the menu will not have a tear-off feature, and choices will be added starting at position 0.

您可以在此示例中看到不同之处:

You can see the difference in this example:

from tkinter import *

root = Tk()

menubar = Menu(root)

tearoff = Menu(menubar, tearoff=1)
tearoff.add_command(label="Tearoff")
menubar.add_cascade(label="Tearoff", menu=tearoff)

notearoff = Menu(menubar, tearoff=0)
notearoff.add_command(label="No Tearoff")
menubar.add_cascade(label="No Tearoff", menu=notearoff)

root.config(menu=menubar)
root.mainloop()
