I want to display data from mongoDB to treeview in Python tkinter

I saw this video: https://www.youtube.com/watch?v=W0l0r0PekvM&t=20s
The code could display data but it display by many Grid together so i can not create a Scrollbar.
you can see the function display data in CRUD() -> creategrid(n)
sorry for my bad English ^^
my code:

how to get tkinter messagebox pop in front of toplevel in class

Is there a way to get the messagebox to appear in front of the toplevel?
code:
showwarning('warning','input four parameters!') shows the messagebox in front of mainwindow not toplevel window.
I checked the similar question root = Tk() texto = Toplevel(root) showinfo("title", "message") and the solution is ,showinfo("title", "message",parent=texto)
while I use class,there is no parent defination.

How to add Checkbox to every row of table to update/delete the row data from phpmyadmin in tkinter

May i know where and how do i need to do. I want to add a checkbox in every row and when it checked, the button of update or delete will only effect to the checked row.
I am new in python and currently i'm doing this for my project gui, is that anyone can help or if any suggestion you're welcome. Thanks
Below is my code:
from tkinter import *
from tkinter import messagebox
import mysql.connector
win = Tk()
win.title("Admin Signup")
win.geometry("750x400+300+90")
frame1 = Frame(win)
frame1.pack(side = TOP, fill=X)
frame2 = Frame(win)
frame2.pack(side = TOP, fill=X)
frame3 = Frame(win)
frame3.pack(side = TOP, padx = 10, pady=15)
frame4 = Frame(win)
frame4.pack(side = TOP, padx = 10)
frame5 = Frame(win)
frame5.pack(side = LEFT, padx = 10)
lbl_title = Label(frame1, text = "User List", font = ("BOLD 20"))
lbl_title.pack(side = TOP, anchor = "w", padx = 20, pady = 20)
btn_register = Button(frame2, text = "Register User")
btn_register.pack(side = TOP, anchor = "e", padx=20)
lbl01 = Label(frame3, text="Username", width=17, anchor="w", relief="raised")
lbl01.grid(row=0, column=0)
lbl02 = Label(frame3, text="Password", width=17, anchor="w", relief="raised")
lbl02.grid(row=0, column=1)
lbl03 = Label(frame3, text="Full Name", width=17, anchor="w", relief="raised")
lbl03.grid(row=0, column=2)
lbl04 = Label(frame3, text="Ic Number", width=17, anchor="w", relief="raised")
lbl04.grid(row=0, column=3)
lbl05 = Label(frame3, text="Staff Id", width=17, anchor="w", relief="raised")
lbl05.grid(row=0, column=4)
mydb = mysql.connector.connect(
host = "localhost",
user = "username",
password = "password",
database = "adminacc"
)
mycursor = mydb.cursor()
mycursor.execute("SELECT * FROM acc")
i = 0
for details in mycursor:
for j in range(len(details)):
e = Entry(frame4, width=17, relief=SUNKEN)
e.grid(row=i, column=j)
e.insert(END, details[j])
e.config(state=DISABLED, disabledforeground="blue")
i = i+1
btn_update = Button(frame5, text = "Update")
btn_update.grid(row=0, column=0, padx=15)
btn_delete = Button(frame5, text = "Delete")
btn_delete.grid(row=0, column=1)
win.mainloop()

Since every row behaves the same, suggest to use a class to encapsulate the behavior:
class AccountInfo:
def __init__(self, parent, details, row):
self.entries = []
# create entry box for each item in 'details'
for col, item in enumerate(details):
e = Entry(parent, width=17, relief=SUNKEN, disabledforeground='blue', bd=2)
e.grid(row=row, column=col)
e.insert(END, item)
e.config(state=DISABLED)
self.entries.append(e)
# create the checkbutton to select/deselect current row
self.var = BooleanVar()
Checkbutton(parent, variable=self.var, command=self.state_changed).grid(row=row, column=col+1)
def state_changed(self):
state = NORMAL if self.selected else DISABLED
# enable/disable entries except username
for e in self.entries[1:]:
e.config(state=state)
#property
def selected(self):
return self.var.get()
#property
def values(self):
return tuple(x.get() for x in self.entries)
Then using the class to create the required rows for each record retrieved from database:
mycursor.execute("SELECT * FROM acc")
accounts = [] # used to store the rows (accounts)
for row, details in enumerate(mycursor):
acc = AccountInfo(frame4, details, row)
accounts.append(acc)
The saved accounts can then be used in the callbacks of Update and Delete buttons:
def update_accounts():
for acc in accounts:
if acc.selected:
print(acc.values)
# do whatever you want on this selected account
btn_update = Button(frame5, text="Update", command=update_accounts)
Same logic on Delete button.
Note that you can modify the AccountInfo class to add functionalities that suit what you need.

Tkinter/class variable/method/widget.get() from another class issue in python 2.7

I am attempting to write a python program that utilizes Tkinter window switching OOP classes. On the starting page, there is an entry form where the user fills in the relevant fields. After filling the form the button 'to tests' is clicked where the user can select the test after switching frame/window, and the user information entered is simultaneously saved in the specified directory as a .txt file as a result of this button running several methods in class Startpage. The problem occurs when data is received by clicking on the yes or no buttons in the test 1 page.
This page operates in a different class, yet requires a return value from method get_info() defined in the Startpage class to get the user information (filename) entered to create a second .txt file to store raw data, storing appended 'yes' or 'no' strings depending on the button clicked in test 1's GUI window.
However this file is never created since Test1 is not receiving any entry data from Startpage class/window, therefore cannot assign a filename (call the get_info() containing the widget.get() functions) for the second .txt file.
The information is obtained in by the methods in the class correctly and everything works fine. However the problem arises when Test1 asks to receive the widget.get() variables/methods from Startpage.
The error thrown is the following IndexError:
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Users\Rylan\Anaconda\lib\lib-tk\Tkinter.py", line 1532, in __call__
return self.func(*args)

str(Day) + "_" + str(Month) + "_" +
IndexError: string index out of range
I am very new to OOP programming and to my knowledge this could be caused by:
Not properly referring/calling the Startpage instance, therefore the variables are not received by the Test1, therefore calling the get_info() method results in with nothing received by the nested widget.get() functions/variables in get_info() method.
Basically, what is the reason for this IndexError and how do I fix it to get the filename created/returned from the get_info() method in class Startpage sent to/called by class Test1?
I have seen similar questions relating to class variable and method calling from a different class, however none of which consider the case for window/frame switching Tkinter applications.
Here is the simplified code below (might not seem like it) which is able to be run (you may have directory path existence issues, just change path to whatever can be easily located for you to save the .txt files)

Your problem is that when you write:
def get_t_info(self):
self.gettheinfo = Startpage(app, self.controller).get_info()
return self.gettheinfo
you create a new StartPage where the Entries are empty.
Then
Name = self.firstnameentry.get()
...
foldername = (str(Name[0])
tries to get the first character of an empty string.
I think the solution should be something like:
def get_t_info(self):
return self.controller.frames[Startpage]
