[Tkinter] Programmatically creating buttons that remember their positions

[DeaD_EyE]

With a trick, you could use command with partial, to call the callback together with the instance of the button itself as the first argument.

Example:

from tkinter import Tk, Button
from tkinter.messagebox import showinfo
from itertools import product
from functools import partial


class Gui(Tk):
    def __init__(self):
        super().__init__()
        self.setup()
        self.selected: None | Button = None

    def setup(self):
        for number, (col, row) in enumerate(product(range(10), range(5))):
            button = Button(self, text=f"Button {number:02d}")
            # callback, which also submits the button innstance to the function
            button["command"] = partial(self.clicked, button)
            button.grid(row=row, column=col)

    def clicked(self, button: Button):
        print(button["text"])
        if self.selected:
            self.selected, selected = None, self.selected

            grid1 = button.grid_info()
            grid2 = selected.grid_info()
            button.grid_configure(row=grid2["row"], column=grid2["column"])
            selected.grid_configure(row=grid1["row"], column=grid1["column"])
            showinfo(
                "Button position changed",
                f"{selected['text']} swapped with {button['text']}",
            )

        else:
            self.selected = button

if __name__ == "__main__":
    Gui().mainloop()
