从 n 个单选按钮中获取每个单选按钮组的值

Question

所以我有一个场景，当必须创建“n”个独立无线电组时，我们将能够独立地检索每个无线电组的值。

当前代码为我提供了最后一个单选组的值，与我按下的按钮无关。

import tkinter # note that module name has changed from Tkinter in Python 2 to tkinter in Python 3
from tkinter import *
from tkinter import messagebox
top = tkinter.Tk()
top.title("NA")

a = int(input("Enter the number of frames"))

btn = [""]*a

def commd():
        print(i)
        print("Value changed to new value", values[i],'with value', values[i].get())
        #print('Update in value')

values = [tkinter.IntVar() for i in range(len(btn))]
print(len(values))


for i in range(len(btn)):
    print(i)
    txt = "Button_Number", (i+1)
    rtxt1 = 'Radio Button1',i+1
    rtxt2 = 'Radio Button2',i+1
    abc = Button(top, text = txt, activebackground = "Green", fg = "Blue", bg = "Red", height =5, command = aa)
    R1 = Radiobutton(top, text = "START", activebackground = "Green", fg = "Blue", bg = "Red", height = 2,variable = values[i],value=0,command = commd)
    R2 = Radiobutton(top, text = "STOP", activebackground = "Green", fg = "Blue", bg = "Red", height = 2,variable = values[i],value=1,command = commd)

    abc.grid(row = i+i, column = 0,rowspan = 2)
    R1.grid(row = i+i, column = 1)
    R2.grid(row = i+i+1,column = 1)

mainloop()

Answer 1

使用.bind(... 而不是command=... ...

输出：

Radio Button1.0 START
Radio Button2.1 STOP
Radio Button1.2 START

import tkinter as tk


class App(tk.Tk):
    def __init__(self):
        super().__init__()
        self.title("NA")

        for i in range(3):
            print(i)
            variable = tk.StringVar()
            for n, text in enumerate(('START', 'STOP'), 1):
                r = tk.Radiobutton(self, text=text, value=text, variable=variable)
                r.bind('<ButtonRelease-1>', self.on_click)
                r._group = f'Radio Button{n}.{i}'
                r._variable = variable
                r.grid(row=i, column=n)

    def on_click(self, event):
        _ = self
        w = event.widget
        print(w._group, w._variable.get())


if __name__ == '__main__':
    App().mainloop()
