无法获取组的变量值ttk.复选按钮

Question

我正在创建3组ttk.复选按钮，使用类clsGrpCheckButton。 问题是我只能访问上一个创建的组的状态，而不能访问上一个组的状态。你知道吗

当单击任何组的某个checkbutton时，我希望得到该组中checkButtons check的列表（使用chkGrpGetValue方法是每个checkbutton的命令参数）

但是，无论单击哪个按钮，该方法都只返回最后一个组的状态

下面是重新创建问题的代码，并在附件中显示了问题的图片

谢谢你的帮助。 Rgds公司

最后，我提出了一个解决方案，在将命令分配给每个checkbutton时使用partial。 如果有人面临类似的问题，下面是完整的代码

import tkinter as tk
from tkinter import ttk
import pandas as pd
from functools import partial

class clsGrpCheckButton():
    def __init__(self,pContainer, pLstVal,pCommand,pInitValue=True): 

        self.grpChk=[0]*len(pLstVal)   
        self.grpKey=[0]*len(pLstVal)
        self.grpLstVal = [0]*len(pLstVal)
        self.grpVariable= [0]*len(pLstVal)
        self.grpActiveKeys = [0]

        for l,t in enumerate(pLstVal):
            #l : index of the list of tuples
            self.grpKey[l] = t[0]
            self.grpLstVal[l] = t[1]
            self.grpVariable[l] = tk.StringVar()
            self.grpChk[l] = ttk.Checkbutton(pContainer, text=self.grpLstVal[l],
                                   state='active' ,
                                   onvalue= self.grpKey[l], 
                                   offvalue= '', 
                                   variable =  self.grpVariable[l], 
                                   command=partial(pCommand,self))

            #get default value
            if pInitValue :
                self.grpVariable[l].set(self.grpKey[l])
                self.grpActiveKeys.append(self.grpKey[l])
