Python tk.StringVar() in a dict won`t change with entry - python-3.x

Question

I'm quite new to Python and have a problem which I can't solve.
I want to write a Class which displays a configuration file (dict) in a tkinter frame. It should choose a tk.widged by type of value and for bool values create checkboxes, and for int and strings it should create entries.
After all it should give back a dict with the same keys, but the values changed to tk.*Var()
However, with the checkboxes there is no problem.
But the int and strings from the entries will not be written through the save_config() function.
It seems the tk.IntVar() and the tk.StringVar() don't update when typing something in the entries.
Hope my question is clear.
Can anybody please help?
code updated like asked by Bryan Oakley:
It also contains the changes suggested by Martin Finke which brings the solution for me!!
#!/usr/bin/env python3.9
import tkinter as tk
from tkinter import ttk
class MainFrame(tk.Tk):
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self)
self.test_dict = {"name": "Ares"}
self.columnconfigure(0, weight=1)
self.rowconfigure(0, weight=0)
self.save_config_button = ttk.Button(
self, text="Print Configuration", command=self.save_config)
self.save_config_button.grid(row=0, column=0, padx=5, pady=5)
self.configuration_frame = ConfigurationFrame
self.config_frame = self.configuration_frame(
self, "Configurations", self.test_dict)
self.config_frame.grid(row=1, column=0, padx=5, pady=5)
self.configuration = self.config_frame.get_configuration()
def save_config(self):
conf = {}
for key, value in self.configuration.items():
conf[key] = value.get()
print(conf)
class ConfigurationFrame(tk.LabelFrame):

self.configuration = {}
self.rowconfigure(0, weight=0)
self.columnconfigure(0, weight=1)
count = 0
for key, value in config.items():
if type(value) == str:
name = key
entry_text = tk.StringVar(self)
entry_text.set(value)
frame_label = tk.Frame(
self, height=1)
frame_label.grid(
row=count, column=0, padx=10, pady=2, sticky=tk.W)
self.entry_str = ttk.Entry(
frame_label, textvariable=entry_text, text=name, width=10)
self.entry_str.grid(row=0, column=0, padx=5,
pady=2, sticky=tk.W)
self.entry_str.insert(tk.END, str(value))
self.name_label = tk.Label(
frame_label, text=name)
self.name_label.grid(row=0, column=1, padx=5,
pady=2, sticky=tk.W)
self.configuration[name] = self.entry_str
count += 1
def get_configuration(self):
return self.configuration
def main():
MainFrame().mainloop()
if __name__ == "__main__":
main()
Thanks to enyone!

I suggest a simple change in the __ init __ function of the ConfigurationFrame class:
line self.configuration[name] = entry_int_txt replace self.configuration[name] = self.entry_int
line self.configuration[name] = entry_text replace self.configuration[name] = self.entry_str
