在MVC模式中，从tk.顶层在Tkinter和Python中类到控制器

Question

我已经实现了MVC模式。我有一个主窗口，其中有一个菜单项“文件”，一个输入wiget和按钮1。单击文件，然后单击otherwin选项，将打开一个新窗口。第二个窗口还有一个条目wiget和一个按钮。教室里有两个班视图.py即视图和genTool。
当我单击主窗口上的按钮1时，我可以访问控制器.py方法。但是在第二个窗口我不能进入控制器.py方法。[通过@Reblochon Masque的实施建议解决问题] 第二个问题是从控制器类的genTool类的入口wiget接收数据。 请提出解决方案。下面是最低可行的代码。你知道吗

你知道吗控制器.py-以python3运行此文件控制器.py [编辑建议@stovfl]

from model import Model
from view import View

class Controller:
    def __init__(self):
        self.model= Model()
        self.view= View(self)
        self.genTool=None


    def main(self):

        self.view.main()
#@stovfl
    def on_button_click(self,  caption):
        print(f' Inside controller  data for {caption} recieved')
        if self.view.gen_tool is not None:
            self.gen_tool=genTool()

        self.model.value1=self.view.value_var1   
        result= self.model.recogniseButton(caption)
        self.view.value_var1.set(result)


# old varient
    #def on_button_click(self,  caption):
        #print(f' Inside controller  data for {caption} recieved')
        #self.model.value1=self.view.value_var1  
        #self.model.value2= self.view.value_var2  # **Donot get the value #here**
        #print(self.model.value1.get())
        #result= self.model.recogniseButton(caption)
        #self.view.value_var1.set(result)
if __name__ == "__main__":
    app = Controller()
    app.main()

你知道吗视图.py [编辑]

import tkinter as tk
from tkinter import ttk

class genTool(tk.Toplevel):
    BUTTON_CAPTION =['Button2']
    def __init__(self, parent,controller):
        super().__init__(parent)

        self._make_buttons()

    def _make_entry(self):
        self.value_var2=tk.StringVar()
        self.ent =tk.Entry(self, textvariable= self.value_var2)

                lambda button= caption: self.controller.on_button_click(button)
                )
                )

你知道吗型号.py你知道吗

class Model:

    def __init__(self):
        self.value1 =''
        self.value2 =''
    def recogniseButton(self, caption):

        if caption == 'Button1':
            print('Inside the Model Button1  registered. ')
            self.value= ''
            return self.value
        if caption == 'Button2':
            print("Inside the Model Button2  registered. This button is  toplevel")
            self.value= ''
            return self.value
