创建用于存储Tkinter按钮的2D列表

Question

Trying to create a method that creates 64 buttons. This method will append the buttons to a two dimensional list and put them on the tkinter canvas using .grid(). Not exactly sure what the problem is. When running the code it does literally nothing, no error, no code 0 not even the tkinter window appears. The method is below with the rest of its class. I also posted the master class, anything helps.

import Tkinter as Tk
import ttk

# Fonts used throughout the class

LARGE_FONT = ("Verdana", 14)
SMALL_FONT = ("Verdana", 10)

# Game Board

board = [['r', 'n', 'b', 'q', 'k', 'b', 'n', 'r'],
         ['p', 'p', 'p', 'p', 'p', 'p', 'p', 'p'],
         [' ', ' ', ' ', ' ', ' ', ' ', ' ', ' '],
         [' ', ' ', ' ', ' ', ' ', ' ', ' ', ' '],
         [' ', ' ', ' ', ' ', ' ', ' ', ' ', ' '],
         [' ', ' ', ' ', ' ', ' ', ' ', ' ', ' '],
         ['P', 'P', 'P', 'P', 'P', 'P', 'P', 'P'],
         ['R', 'N', 'B', 'K', 'Q', 'B', 'N', 'R']
         ]


class Board(Tk.Frame):

    def __init__(self, parent, controller):

        Tk.Frame.__init__(self, parent)

        # init variables
        self.turn = True
        self.buttons = []
        self.board = board

        # Header
        label = Tk.Label(self, text="Chess", font=LARGE_FONT)
        label.pack(pady=10, padx=10)

        # Game
        # Sets game board
        self.set_buttons()

        # Sets game board
        # self.set_buttons2()

        back_button = ttk.Button(self, text="Main Menu", command=self.main_menu(controller))
        back_button.pack(side=Tk.BOTTOM, fill=Tk.BOTH)

    # Stores buttons in list for later use
    # Places buttons on canvas.
    def set_buttons(self):
        for i in range(8):
            self.buttons.append([])
            for j in range(8):
                self.buttons[i].append(ttk.Button(self, text=self.board[i][j]))
                self.buttons[i][j].configure(command=self.piece_control)
                self.buttons[i][j].grid(row=i, column=j, sticky="nsew")

    def piece_control(self):
        pass

    @staticmethod
    def main_menu(controller):
        from MainMenu import MainMenu
        return lambda: controller.show_frame(MainMenu)

I will also add the master class just in case that is where the problem is.

from MainMenu import MainMenu
from Board import Board
from Rules import Rules
from Options import Options
import Tkinter as Tk


class Main(Tk.Tk):

    def __init__(self, *args, **kwargs):

    Tk.Tk.__init__(self, *args, **kwargs)

        Tk.Tk.title(self, "Chess")

        container = Tk.Frame(self)
        container.pack(side="top", fill="both", expand=True)
        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)

        self.frames = {}

        for F in (MainMenu, Board, Options, Rules):

            frame = F(container, self)
            self.frames[F] = frame
            frame.grid(row=0, column=0, sticky="nsew")

        self.show_frame(MainMenu)

    def show_frame(self, cont):

        frame = self.frames[cont]
        frame.tkraise()

# Creates Object of main and loops it.

Application = Main()
Application.geometry("650x650")
Application.mainloop()

it works great for me, it does create an 8x8 matrix on the root.

import ttk
from Tkinter import *
root = Tk()
buttons = []

def set_buttons():
    for i in range(8):
        buttons.append([])
        for j in range(8):[![enter image description here][1]][1]
            buttons[i].append(ttk.Button(text='3'))
            buttons[i][j].configure(command=com)
            buttons[i][j].grid(row=i, column=j, sticky="nsew")

def com():
    print 3

set_buttons()
root.mainloop()

if you're still having problems then its probably because of other parts in your code, so please post a more extensive code block for us to find the problem.

After further debugging apparently using .pack() with .grid() was proving to be quite chaotic. Made a few simple changes to the init function by changing the .pack() methods to .grid() and it works like a charm.

def __init__(self, parent, controller):

    Tk.Frame.__init__(self, parent)

    # init variables
    self.turn = True
    self.buttons = []
    self.board = board

    # Header
    label = Tk.Label(self, text="Chess", font=LARGE_FONT)
    label.grid(row=0, column=3, columnspan=2, sticky="nsew")

    # Game
    # Sets game board
    self.set_buttons()

    back_button = ttk.Button(self, text="Main Menu", command=self.main_menu(controller))
    back_button.grid(row=8, column=3, columnspan=2, sticky="nsew")
