Tkinter-單擊按鈕時在類之間傳遞按鈕網格值

我正在嘗試使用 Tkinter 在 Python 中創建一個基本的戰艦游戲。

下面是我的代碼的一個非常簡化的版本。本質上，我正在創建一個 10*10 的按鈕網格并使用.grid. 我想要做的是單擊這些按鈕之一并將該按鈕網格值 (x, y) 從GameBoard類傳遞到Battleship類以定位船舶。

我曾嘗試使用self.row = rowand self.column = column，但是當我這樣做時，我立即收到一個屬性錯誤，'GameBoard' object has no attribute 'row'.

import tkinter as tk

class GameBoard:
    def __init__(self):
        self.mw = tk.Tk()
        self.size = 10

    def build_grid(self):
        for x in range(self.size):
            for y in range(self.size):
                self.button = tk.Button(self.mw, text = '', width = 2, height = 1,\
                command = lambda row = x, column = y: self.clicked(row, column))
                self.button.grid(row = x, column = y)
            
    def clicked(self, row, column):
        print(row, column)
        self.row = row
        self.column = column

class Battleship:
    def __init__(self, board):
        self.gboard = board

    def position_ship(self):
        x = self.gboard.row
        y = self.gboard.column
        for i in range (3):
            self.submarine = tk.Button(self.gboard.mw, background = "black", text = '',\
                                   width = 2, height = 1)
            self.submarine.grid(row = x, column = y)
              
def main():
    gboard = GameBoard()
    gboard.build_grid()
    bt = Battleship(gboard)
    bt.position_ship()    
main()

uj5u.com熱心網友回復：

正如@ acw1668在評論中指出，問題是gboard屬性row和column當你呼叫還沒有被創建bt.position_ship()的main()功能。

我不知道你的整體游戲設計，但一個非常簡單的解決GameBoard.__init__()方法是在方法中為它們分配一個隨機的棋盤位置。

我還修改了代碼以顯示bt.position_ship()單擊按鈕時如何呼叫。這是通過將BattleShip實體傳遞bt給build_grid()函式來完成的，因此它可以包含在對clicked()方法的呼叫中，現在可以在呼叫時呼叫它。

from random import randrange
import tkinter as tk

class GameBoard:
    def __init__(self):
        self.mw = tk.Tk()
        self.size = 10
        self.row = randrange(self.size)
        self.column = randrange(self.size)

    def build_grid(self, bt):
        for x in range(self.size):
            for y in range(self.size):
                self.button = tk.Button(self.mw, text='', width=2, height=1,
                                        command=lambda row=x, column=y:
                                            self.clicked(bt, row, column))
                self.button.grid(row=x, column=y)

    def clicked(self, bt, row, column):
        print(row, column)
        self.row = row
        self.column = column
        bt.position_ship()


class Battleship:
    def __init__(self, board):
        self.gboard = board

    def position_ship(self):
        x = self.gboard.row
        y = self.gboard.column
        for i in range (3):
            self.submarine = tk.Button(self.gboard.mw, background="black", text='',
                                       width=2, height=1)
            self.submarine.grid(row=x, column=y)


def main():
    gboard = GameBoard()
    bt = Battleship(gboard)
    gboard.build_grid(bt)
    bt.position_ship()
    tk.mainloop()

main()
