创建面向对象的 tkinter 程序：尝试将字符串值传递给在单独类中定义的方法

问：

我正在尝试创建一个面向对象的 tkinter 程序。截至目前，我已经写了 4 节课。类 1 是主程序，类 2 是主框架，类 3 是 AlumniSearch 框架，类 4 是 AlumniProfile 显示框架，其中该框架显示在名为“alumniProfile”的导入类中编译的所有信息。

我的目标是使用在“alumniSearch”类中选择的字符串值来更新/更改在“alumniProfiles”中创建的对象，以便在“alumniProfiles”页面上显示该对象。

import tkinter as tk
from tkinter import ttk
from personClass import alumniProfile

class alumniSearch(ttk.Frame):
    def __init__(self, container, controller, **kwargs):
        super().__init__(container, **kwargs)

        self.searchBox = ttk.Entry(self)
        self.searchBox.grid(row=1, column=1)

        searchButton = ttk.Button(self, text='Go', command=self.searchAlumni)
        searchButton.grid(row=1, column=2)

        self.selectedResult = tk.StringVar()
        self.resultsBox = tk.Listbox(self, listvariable=self.selectedResult, width=30)
        self.resultsBox.pack(side='left', fill='x')

        viewProfileButton = ttk.Button(self, text='View Alumni Profile', command=self.passName)
        viewProfileButton.pack(side='left')

    def passName(self):
        selectedName = ''
        for i in self.resultsBox.curselection():
            selectedName = self.resultsBox.get(i)
        
        # need something here to pass the selectedName to the self.alumniPerson object in alumniProfiles class


class alumniProfiles(ttk.Frame):
    def __init__(self, container, controller, **kwargs):
        super().__init__(container, **kwargs)
        
        self.selectedName = 'Mr. Bryan B. Kornegay Jr.'  # default name until another name is 
        # selected in alumniSearch class
        self.alumniPerson = alumniProfile(self.selectedName)  # builds object using the name given
        personValues = self.alumniPerson.compileValues()  # initializes the method to create the label

        self.valuesVariable = tk.StringVar()
        self.valuesVariable.set(personValues)

        self.displayValues = ttk.Label(self, textvariable=self.valuesVariable)
        self.displayValues.pack(side='left')


    def setName(self, name):  # needs to dynamically update the label displayed on the page
        self.selectedName = name
        self.valuesVariable.set(name)
        return self.valuesVariable
