如何在 tkinter 的函数中打印复选框的总点击数？

Question

我正在尝试在 class 中创建一个函数 函数，我想计算点击了多少个复选框。

# This function assesses number of clicked items in my class's list
    def badper(self):
        window=Tk()
        window.config(bg='lightgreen')
        # total = 0
        def show(self):
            new_label = Label(window, text=var.get()).pack()
        var=IntVar()
        def create_check_button(self,i):
            var = IntVar()
            c=Checkbutton(window,text=self.badcharacter[i],variable=var)
            c.pack()
            # if c == 1:
            #     global total
            #     total += 1
        # This loop creates checkboxes in the equivalent of number items of my list
        for i in range(6):
            create_check_button(self,i)

        # This button should show how many items clicked so far
        my_button=Button(window,text="show", font=("Arial", 12, "bold"),command=show(self)).pack()

此代码实现了正确的结果，显示的集合总数 Checkbuttons。

代码中的注释解释了这个简化代码段中的问题。

import tkinter as tk

window = tk.Tk()
window.config(bg='lightgreen')

store_var = []

def show():
    total = 0
    # This is one way to display results
    for a in store_var:
        if a.get():
            total = total + 1
    my_label["text"] = f"Total = {total}"

def create_check_button(i):
    var = tk.IntVar()
    # no information on badcharacter list supplied
    c = tk.Checkbutton(
        window, text = i, onvalue = 1, offvalue = 0, variable = var)
    c.pack()
    # Save each IntVar in list for use by function show()
    store_var.append(var)

for i in range(6):
    create_check_button(i)

# my_label is referenced in function show() so define my_label separately from pack
my_label = tk.Label(window, text = "Output")
my_label.pack()

# Button is not referenced anywhere so combining declaration and pack management is OK
tk.Button( window, text = "show", font = "Arial 12 bold", command = show).pack()

window.mainloop()

这是关于我的项目的图片 I use stepI button in order to display checkbotton window

Thank you derek I am appreciated but when I clicked the show button The result shows "0"

I used the above answer in the program I saw that I could not change the result the total remained the same(0). So I tried different approach but this time I could not run checkbutton properly. The store_var displays either "000000" or "111111" (these numbers 0,1 related with item number in my list(i))

def badper(self):
    window=tk.Tk()
    window.geometry("300x300")
    window.config(bg='lightgreen')

    store_var= []

    def show():

        total = 0
        # This is one way to display results
        for a in store_var:
            if a.get():
                total = total + 1
        my_label["text"] = f"Total = {total}"

    def create_check_button(i):
        var = tk.IntVar()
        # for i in self.badcharacter:

        c = tk.Checkbutton(window, text=i,onvalue=1,offvalue=0,variable=var)
        c.pack()
            # Save each IntVar in list for use by function show()
        store_var.append(var)




    for i in self.badcharacter:
        create_check_button(i)

    # my_label is referenced in function show() so define my_label separately from pack
    my_label = tk.Label(window, text="Output")
    my_label.pack()
    result = tk.Button(window,text="show",font=("Arial",12,"bold"),command=show).pack()
    window.mainloop()

I found it! Finally :) Thank you Derek you helped me a lot finding this solution. the link s question answer helped me :

我用 Toplevel() 函数替换了 Tk() 并且它起作用了:)

def badper(self):
    window=tk.Toplevel()
    window.geometry("300x300")
    window.config(bg='lightgreen')

    store_var= []

    def show():

        total = 0
        # This is one way to display results
        for a in store_var:
            if a.get():
                total = total + 1
        my_label["text"] = f"Total = {total}"

    def create_check_button(i):
        var = tk.IntVar()
        # for i in self.badcharacter:

        c = tk.Checkbutton(window, text=i,onvalue=1,offvalue=0,variable=var)
        c.pack()
            # Save each IntVar in list for use by function show()
        store_var.append(var)




    for i in self.badcharacter:
        create_check_button(i)

    # my_label is referenced in function show() so define my_label separately from pack
    my_label = tk.Label(window, text="Output")
    my_label.pack()
    result = tk.Button(window,text="show",font=("Arial",12,"bold"),command=show).pack()
    window.mainloop()
