#102086 — tkinter newbie question

See my code below (which works). I'd like to have the 2nd window as a class in a separate unit. How do I code that unit and how do I call it from my first unit?

As always, thanks for all help!




#!/usr/bin/env python
"""
""" 
from tkinter import *
from settings import *

class window1():

    def open_window2(self):
        t = Toplevel(self.root)
        t.title('New window')
        t.geometry('262x65+200+250')
        t.transient(self.root)

    def setup_menu(self):
        self.menubar = Menu(self.root)
        self.menu1 = Menu(self.menubar, tearoff=0 ) 
        self.menu1.add_command(label="Settings",   accelerator='Ctrl+S', command=self.open_window2)
        self.menubar.add_cascade(label="Menu 1", menu=self.menu1)  
        self.root.config(menu=self.menubar)        

    def __init__(self):
        self.root = Tk()
        self.root.title('Window #1')
        self.setup_menu()
        self.root.geometry('800x600+200+200')
        #
        self.root.mainloop()

if __name__ == '__main__':
    
    w1 = window1()

Move the code from open_window2() into a class in settings.py, e. g.


import tkinter as tk # avoid star-import

class SettingsWindow(tk.Toplevel): # Class names start with uppercase letter
                                   # Prefer self-explaining names
    def __init__(self, root):
        super().__init__(root)
        self.title('New window')
        self.geometry('262x65+200+250')
        self.transient(root)

Then use it in your main script:

import settings

          settings.SettingsWindow(self.root)

Dang - almost there. Using your code, I get the new window with the specified geometry and its type is transient, as expected.

Its caption, however, is NOT the caption specified, but the caption of the first window, leaving me with 2 windows with identical caption.

Any idea why?
