Question

我想重命名部件，如果它显示“Open Space”并在点击时全部禁用按钮。

from tkinter import *

board = Tk()

board.geometry("400x500")
board.title("Board")

b = Button(board, text="Open Space")
b.grid(row=0, column = 1)

c = Button(board, text="Open Space")
c.grid(row=0, column = 2)

d = Button(board, text="Open Space")
d.grid(row=1, column = 0)

e = Button(board, text="Open Space")
e.grid(row=1, column = 1)

f = Button(board, text="Open Space")
f.grid(row=1, column = 2)

g = Button(board, text="Open Space")
g.grid(row=2, column = 0)

h = Button(board, text="Open Space")
h.grid(row=2, column = 1)
i = Button(board, text="Open Space")
i.grid(row=2, column = 2)

board.mainloop()

Answer 1

通常，您可以使用

将功能分配给Button

Button(..., command=function_name)

但是你需要访问按钮，所以你必须首先创建按钮，然后用参数 - 按钮实例来协助函数 - 这个函数将改变文本并禁用按钮。

b['command'] = lambda:change(b)

# or 

b.config(command=lambda:change(b))

import tkinter as tk

# --- function ---

def change(widget):
    widget.config(text='o', state='disabled')
    #widget['text'] = 'o'
    #widget['state'] = 'disabled'

# --- main ---

root = tk.Tk()

a = tk.Button(root, text="Open Space")
a['command'] = lambda:change(a)
a.pack()

b = tk.Button(root, text="Open Space")
b.config(command=lambda:change(b))
b.pack()

root.mainloop()

编辑：

也许您不需要禁用按钮，但您需要删除已分配的功能：

def change(widget):
    widget.config(text='o', command=None)

Answer 2

如果您想更改Button小部件，只需编写想要执行的更改：

btnname.configure(state=tk.DISABLED, text='New Text', command=newcommand)

根据您的情况更改按钮b：

board.b.configure(state=tk.DISABLED, text='New Text', command=newcommand)

您使用state = tk.DISABLED禁用tk.Button并使用state = tk.NORMAL启用它。如果您不想更改命令，请不要包含它。

对于ttk.Button，状态值为state ='disabled'以禁用它，state ='！disabled'再次启用它

我想重新命名按钮并同时禁用它
