python - 如何在 tkinter 中以编程方式将相同的操作关联到一组按钮？

Question

我一直在从事一个 Python/Tkinter 项目，该项目需要从下面的列表中以编程方式创建按钮。

当按下某个按钮时，我希望该按钮变为 "sunken" 直到按下另一个按钮，在那个阶段该按钮将变为 "sunken" , 并且第一次点击的按钮将变为 'normal'。

到目前为止，如果不对每个按钮分别进行编码，我还不知道如何做到这一点。

理想情况下，relief 将在 press() 函数中设置。

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()

您正在描述一组单选按钮的行为，因此您应该使用它们。

方便的是单选按钮有一个属性 indicatoron

Normally a radiobutton displays its indicator. If you set this option to zero, the indicator disappears, and the entire widget becomes a “push-push” button that looks raised when it is cleared and sunken when it is set. You may want to increase the borderwidth value to make it easier to see the state of such a control.

因此，当设置为零时，它会精确地您的要求。
