用按钮构建一个棋盘，它总是一个正方形

Question

我正在尝试构建一个由按钮组成的棋盘。我在一行中创建了 3 个小部件。外面有标签（填充），里面我想放一个棋盘。我希望它始终占据屏幕宽度的 90% 并自动调整其高度，使其始终保持为正方形。还必须将按钮设置为始终为正方形，但我也无法处理。你能帮助我吗？class ChessBoard(GridLayout):    def __init__(self, **kwargs):        super(ChessBoard, self).__init__(**kwargs)        self.cols = 8        for i in range(64):            self.cell = Button(text="", size_hint_y=self.height/8, height=self.width/8)            self.add_widget(self.cell)class ChessBoardContainer(GridLayout):    def __init__(self, **kwargs):        super(ChessBoardContainer, self).__init__(**kwargs)        self.orientation='horizontal'        self.cols=3        self.lab1 = Label(text="1")        self.add_widget(self.lab1)        self.board = ChessBoard()        self.add_widget(self.board)        self.lab2 = Label(text="2")        self.add_widget(self.lab2)class CombWidget(BoxLayout):    def __init__(self, **kwargs):        super(CombWidget, self).__init__(**kwargs)        self.orientation='vertical'        self.but1 = Button(text="But1", font_size=40)        self.add_widget(self.but1)        self.chessb = ChessBoardContainer()        self.add_widget(self.chessb)        self.but2 = Button(text="But2", font_size=40)        self.add_widget(self.but2)class MyPaintApp(App):    def build(self):        return CombWidget()现在这是我的结果：我想得到这样的东西（油漆大师；））。也许没有这个标签也可以做到？

要使按钮为正方形，您只需设置 GridLayout 单元格的高度和宽度，并且您正在尝试使用 size_hint 来实现。尝试这个：

from kivy.core.window import Window

class ChessBoard(GridLayout):

    def __init__(self, **kwargs):

        super(ChessBoard, self).__init__(**kwargs)

        self.cols = 8

        winsize = Window.size

        sizedict = {}

        # to set width and height of GridLayout cells, you should make a dict, where the key is col's/row's number and the value is size

        for i in range(self.cols):

            sizedict[i] = winsize[0]/8 #or you can divide it by 10 for example to have some black filling on the sides

        # and then simply do this

        self.cols_minimum = sizedict

        self.rows_minimum = sizedict

这段代码生成的按钮对我来说看起来相当方正。如果您打算为您的棋子使用图像，则按钮将符合这些图像的大小。

from tkinter import Tk, Button

window = Tk ()

squares = []

index = 0

for x in range (8) :

    for y in range (8) :

        squares.append (Button (window, width = 7, height = 4))

        squares [index].grid (row = x, column = y)

        index += 1

window.mainloop ()
