如何在Tkinter中以编程方式将同一操作与一组按钮相关联? [英] How to associate the same operation to a set of buttons programmatically in tkinter?

问题描述

我一直在研究一个Python/Tkinter项目，该项目要求从列表中以编程方式创建按钮，如下所示.

I have been working on a Python/Tkinter project that requires programatically created buttons from a list as below.

当某个按钮被按下时，我希望该按钮成为"sunken"，直到另一个按钮被按下为止，在那个阶段该按钮将成为"sunken"，而第一次单击的按钮将成为'normal'.

When a certain button is pressed, I would like that button to become "sunken" until another button is pressed, at that stage that button would become "sunken", and the button first clicked would become 'normal'.

到目前为止，我还没有弄清楚如何做到这一点，而不必单独对每个按钮进行编码.

So far I can't figure out how to do this without having to code each button individually.

理想情况下，将在press()函数中设置relief.

Ideally the relief would be set in the press() function.

import tkinter


window = tkinter.Tk()
window.title("Practice UI")
window.grid()

numbers = ["1","2","3","4","5","6","7","8","9"]

def buttonCreator(labels):
    n = 0
    button = []
    for x in range(0,3):
        for y in range(0,3):
            if n<=len(labels)-1:
                button.append(tkinter.Button(window, text = labels[n], command = lambda x = labels[n]:press(x)))
                button[n].grid(row = x, column = y)
            n +=1

def press(value):
    print(value)

buttonCreator(numbers)

window.mainloop()

推荐答案

您可以简单地返回button并使用它来访问press()中的按钮:

You could simply return button and use it to access your buttons in press():

import tkinter

window = tkinter.Tk()
window.grid()

# changed to integers so we can loop through the
# values in press() and use them as indices
numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9]

def buttonCreator(labels):
    n = 0
    button = []
    for x in range(0, 3):
        for y in range(0, 3):
            if n <= len(labels) - 1:
                button.append(tkinter.Button(window, text=labels[n],
                                             command=lambda x=labels[n]:press(x)))
                button[n].grid(row=x, column=y)
            n += 1
    return button # added a return statement

def press(value):
    for x in numbers:
        # index is x-1 because 1 is in button[0], etc
        button[x-1]['relief'] = 'sunken' if x == value else 'raised'

button = buttonCreator(numbers)
window.mainloop()
