_tkinter.TclError：python复选框中的未知选项“ -title”错误

Question

我试图使一个类在一次又一次调用该类时显示复选框，而不重写整个代码，而只是通过使用tkinter和python 3.7.2版提供基本变量值。陷入了这个问题。

# easyfunc.py

import tkinter as tk

class checkButton:
    """docstring for checkButton"""
    def __init__(self, title, bg, command):
        super(checkButton, self).__init__()
        self.title = title
        self.bg = bg
        self.command = command
        var = IntVar()
        checkbutton = Checkbutton(master, title=title, bg=bg, command=command, variable=var)
        checkbutton.pack()

------------------------------------------------------------------------------

# try.py

import easyfunc

def helloworld():
    print("helllo")
gui.checkButton("BUTTON", "white", "helloworld")

Traceback (most recent call last):
