I made an application in Python 3.6 that calls another python script to mount a ttk.Treeview screen with the database information and this presented data can be manipulated (change and delete).

It turns out that I can not leave this ttk.Treeview screen with the permanent focus, since when the "alt + tab" key focus changes to the previous screen that called this script.

Can anyone help me? I tried to use transient but I'm not succeeding.

Part of the script that calls the other python script:

def consultacadastro( posi ):
    if str(nrbancoget) != "":
        a = ConsultaCadastroGeral.Inicio()

Part of the program that displays the information ttk.Treeview:

Starting the program

from tkinter import * from tkinter import Tk, Button, ttk, Frame, Toplevel, Label, Entry, StringVar from tkinter import messagebox from Manager import Manager from PgmFuncoes import PgmFuncoes

class GeneralCountryReview:     def Home ():         root = Tk ()         root.title ("Users Query - General")         CustomTree (root) .pack (expand = 1, fill="both")

class CustomTree (Frame):     def init (self, master, * args, ** kwargs):          init (self, master, * args, ** kwargs)

    # Define tamanhos mínimos e máximos da tela
    master.minsize( width = 500, height= 200)       
    master.maxsize( width = 500, height= 200)

    self.focus_force()

    # Define botão de sair da tela
    self.top = Frame(self)
    self.edit_button = Button(self.top, text="Sair", font = "bold", fg = "blue", command=master.destroy)
    self.edit_button.pack(side="top")
    self.top.pack(fill="x")

    self.tree = ttk.Treeview(self)

    # Define tamanho da coluna
    self.tree.column("#0",minwidth=0,width=0)

    # Cria barra de rolagem      
    barra = Scrollbar(self, orient='vertical', command=self.tree.yview)

    # Adiciona barra de rolagem
    self.tree.configure(yscroll=barra.set)
    barra.pack( side = RIGHT, fill=Y )

    self.tree["columns"] = ("one", "two", "tree", "four", "five")
    self.tree.column("one", width=100, anchor="se")
    self.tree.column("two", width=100, anchor="se")
    self.tree.column("tree",width=100, anchor="se")
    self.tree.column("four",width=100, anchor="se")
    self.tree.column("five",width=100, anchor="center")
    self.tree.heading("one", text="Número Banco")
    self.tree.heading("two", text="Número Agência")
    self.tree.heading("tree", text="Conta Corrente")
    self.tree.heading("four", text="Saldo Inicial (R$)")
    self.tree.heading("five", text="Data Inicial")

Thank you in advance.
