How can I bind a combobox to a Radiobutton

I have some Radiobuttons. Depending of what Radio button was selected I want to have different Combobox values. I don't know how I can solve the problem. In a further step I want to create further comboboxes which are dependend on the value of the first.
The following code creates the list of user, but it does not show up in the combobox.
For me it is difficult to understand where the right position of functions is, and if I need a lambda function nor a binding.

Python - Tkinter - invisible text in ttk.Entry in sub window

I'm trying to make a sub window for configuration settings. But the text in the sub window is invisible. I am reading correctly but I cannot see the text. Below is my sample code with the problem:
import tkinter as tk
from tkinter import ttk
from tkinter import Menu
class Frames:
def __init__(self):
self.port_com = None
def main_frame(self, win):
# Main Frame
main = ttk.LabelFrame(win, text="")
main.grid(column=0, row=0, sticky="WENS", padx=10, pady=10)
return main
def dut_configuration_frame(self, win):
# Configuration Frame
dut_config_frame = ttk.LabelFrame(win, text="Config")
dut_config_frame.grid(column=0, row=0, sticky='NWS')
# Port COM
ttk.Label(dut_config_frame, text="Port COM").grid(column=0, row=0)
self.port_com = tk.StringVar()
ttk.Entry(dut_config_frame, width=12, textvariable=self.port_com).grid(column=0, row=1, sticky=tk.EW)
self.port_com.set(value="COM7")
print(self.port_com.get())
class ConfigFrames:
def __init__(self):
self.port_com = None
def main_frame(self, win):
# Main Frame

main.grid(column=0, row=0, sticky="WENS", padx=10, pady=10)
return main
def configuration_frame(self, win):
# Configuration Frame
dut_config_frame = ttk.LabelFrame(win, text="Config")
dut_config_frame.grid(column=0, row=0, sticky='NWS')
# Port COM
ttk.Label(dut_config_frame, text="Port COM").grid(column=0, row=0)
self.port_com = tk.StringVar()
ttk.Entry(dut_config_frame, width=12, textvariable=self.port_com).grid(column=0, row=1, sticky=tk.EW)
self.port_com.set(value="COM5")
print(self.port_com.get())
def menu_bar(win):
def _config():
config_frame = ConfigFrames()
config_window = tk.Tk()
config_window.title("Sub window")
config_window.geometry("200x200")
config_window.resizable(0, 0)
main = config_frame.main_frame(config_window)
config_frame.configuration_frame(main)
config_window.mainloop()
# Menu
menuBar = Menu(win)
win.config(menu=menuBar)
settingsMenu = Menu(menuBar, tearoff=0)
settingsMenu.add_command(label="Config", command=_config)
menuBar.add_cascade(label="Settings", menu=settingsMenu)
frames = Frames()
win = tk.Tk()
win.title("Main window")
win.geometry("200x200")
win.resizable(0, 0)
menu_bar(win)
main = frames.main_frame(win)
frames.dut_configuration_frame(win)
win.mainloop()
As you can see in main window it is visible, but in sub window it is invisible.
And printing in console is correct:

How to add a scrollbar to window made with tkinter

A simple quiz game
I got this code and I need scrollbars, I tried to search how to add it on stackoverflow (ScrolledWindow with tix...) but I still can't get something that works properly. Could someone help me?
from tkinter import *
from random import randint
root = Tk()
root.title("Quiz")
root.geometry("400x300")
class Window:
def __init__(self, question, answer):
self.text = [question, answer]
self.createLabel()
# self.createText()
self.createEntry()
self.createButton()
def retrieve_input(self):
# inputValue = self.textBox.get("1.0", "end-1c")
# print(inputValue)
if self.mystring.get() == self.text[1]:
print("Esatto. è " + self.text[1])
self.left['text'] = "Esatto"
def createLabel(self):
self.labelframe = LabelFrame(root, text="Domanda:")
self.labelframe.pack(fill="both", expand="yes")
self.left = Label(self.labelframe, text=self.text[0])
self.left.pack()
def createText(self):
self.textBox = Text(height=1)
self.textBox.pack()
def createEntry(self):
self.mystring = StringVar()
self.myentry = Entry(root, textvariable=self.mystring).pack()
def createButton(self):
self.but = Button(text="Click", command=self.retrieve_input)
self.but.pack()
for i in range(10):
one = randint(1, 10)
two = randint(1, 10)
Window("Quanto fa " + str(one) + "+" + str(two) + "?", str(one + two))
root.mainloop()
output

With ScrolledFrame it can look like this
I renamed Window into Question because it makes more sense
I use self.question and self.answer instead of self.text = [question, answer] to make it more readable.
I put classes and functions before root = tk.Tk() to make it more readable.
I use import tkinter as tk instead of from tkinter import * to make it more readable.
Question gets inner frame from ScrolledFrame and use as parent for LabelFrame. Other widgets use labelframe as parent.
BTW: you had entry = Entry(..).pack() which assign None to entry because pack()/grid()/place() returns None. I put pack() in next line and now I can get text directly from Entry (without StringVar)
Code

Using .get() within tkinter ScrolledFrame

I am trying to achieve grabbing par02_1 using .get(). I have success writing the rest of the .txt file but my program is not grabbing my gui entry lines. I'm guessing this has something to do with the association self, and the scrollable section, etc. but I can't track this one down. Any help is appreciated.

How can I pop up a messagebox from a menu?

I am a newbie in Python. I want to create a program with Tkinter that takes the entry from the entry "box" and then compares each character of it with the charset and finally pops up a messagebox that shows the phrase. I have almost complete it but I can not make this line work:
info_menu.add_command(label="About",
command=messagebox.showwarning(message="Creator: GakPower\nVersion: 1.0.0\nCreated at 1/5/2017")

message=("The process completed Successfully!\n The Phrase Found!!!!\n", result))
def submit_button_pressed(self):
entry_val = self.entry_value.get()
charset = list(s.ascii_letters + "ΑΒΓΔΕΖΗΘΙΚΛΜΝΞΟΠΡΣΤΥΦΧΨΩαβγδεζηθικλμνξοπρστυφχψω" + s.digits + s.punctuation)
result = ""
x = 0

As furas said in the comments, command= expects a function. So you should replace
info_menu.add_command(label="About",
command=messagebox.showwarning(message="Creator: GakPower\nVersion: 1.0.0\nCreated at 1/5/2017"))
by something like
def show_about():
''' show the about messagebox '''
messagebox.showwarning(message="Creator: GakPower\nVersion: 1.0.0\nCreated at 1/5/2017")
info_menu.add_command(label="About", command=show_about)
