我的问题是：我不知道如何设置 myCheckbutton以使其中一个Checkbuttons 可以匹配所有框（这部分已完成），但是当我想不匹配任何其他框时，这是可能的。当我使用“所有框”选项运行部分代码时，我可以将它们全部“选中”，或者全部取消，但是在按下“所有框”按钮后，我无法取消选中除“所有盒子”。

我的代码的一个关键部分：

onevar = tk.BooleanVar(value=False)
def select_all(): # select all `tk.Checkbutton`
    check_buttons_list = [twovar, threevar, fourvar, fivevar, sixvar, sevenvar]
    for name in check_buttons_list:
        if onevar.get() == True:
            name.set(1)
        if onevar.get() == False:
            name.set(0)

        #below the problem, I don't know what should I write here:
        if name.get() != onevar.set():
            return name.set()

twovar = tk.BooleanVar(value=True)
threevar = tk.BooleanVar(value=True)
fourvar = tk.BooleanVar(value=True)
fivevar = tk.BooleanVar(value=True)
sixvar = tk.BooleanVar(value=True)
sevenvar = tk.BooleanVar(value=True)

one = tk.Checkbutton(
        content,
        text="Match ALL",
        variable=onevar,
        onvalue=True,
        bg="red",
        fg="black",
        command=select_all,
        font=font.Font(family='Helvetica', size="9", weight='bold')
        )
two = tk.Checkbutton(content, text="box1", variable=twovar, onvalue=True, command=select_all)
three = tk.Checkbutton(content, text="box2", variable=threevar, onvalue=True, command=select_all)
four = tk.Checkbutton(content, text="box3", variable=fourvar, onvalue=True, command=select_all)
five = tk.Checkbutton(content, text="box4", variable=fivevar, onvalue=True, command=select_all)
six = tk.Checkbutton(content, text="box5", variable=sixvar, onvalue=True, command=select_all)
seven = tk.Checkbutton(content, text="box6", variable=sevenvar, onvalue=True, command=select_all)

我找到了解决问题的方法：

def select_all(): # select all `tk.Checkbutton`
    check_buttons_list = [twovar, threevar, fourvar, fivevar, sixvar, sevenvar]
    for name in check_buttons_list:
        if onevar.get() == True:
            for name in check_buttons_list:
                name.set(value=True) # instead of `value=True` can be `1`
        if onevar.get() == False:
            pass

onevar = tk.BooleanVar(value=False)
twovar = tk.BooleanVar(value=False)
threevar = tk.BooleanVar(value=False)
fourvar = tk.BooleanVar(value=False)
fivevar = tk.BooleanVar(value=False)
sixvar = tk.BooleanVar(value=False)
sevenvar = tk.BooleanVar(value=False)
