[Tkinter] proper way of coding

[ebooczek]

I have a question of good practice of using tkinter.
Should the main window be created in a function of outside? Making it as a local doesn't seem to be a good idea, but i lack experience, so I'd like to know the proper way of using it.

that is a loaded question.
I'd suggest that you go through a good tutorial.

One I like: Modern Tkinter for Busy Python Developers: Quickly learn to create great looking user interfaces for Windows, Mac and Linux using Python's standard GUI toolkit, not free but almost.

Should the main window be created in a function of outside?

I don't understand this question.

The way I usually do the coding in tkinter is make a class.
Example:

import tkinter as tk

class MainWindow:
    def __init__(self, parent):
        self.label = tk.Label(parent, text='Some text in a label')
        self.label.pack()

        button = tk.Button(parent, text='Press Me', command=self.change)
        button.pack()

    def change(self):
        self.label['text'] = 'Label text changed'
        self.label['bg'] = 'lightblue'
        self.label['fg'] = 'red'

def main():
    root = tk.Tk()
    MainWindow(root)
    root.mainloop()

if __name__ == '__main__':
    main()

I'm starting to like making an App class for the root window.

import tkinter as tk

class MainWindow(tk.Tk):
    """Root window class"""
    def __init__(self, *args, title="Example", **kwargs):
        super().__init__(*args, **kwargs)
        if title:
            self.title(title)
        self.label = tk.IntVar(value=0)
        tk.Label(self, textvariable=self.label).pack()
        tk.Button(self, text='Press Me', command=self.change, width=30).pack(padx=5, pady=5)
 
    def change(self):
        self.label.set(self.label.get() + 1)

def main():
    app = MainWindow()
    app.mainloop()

if __name__ == '__main__':
    main()

Or skip making a main().

if __name__ == '__main__':
    MainWindow().mainloop()
