Question

我建立了一个GUI，要求输入一些用户信息。我正在努力获取按下“继续”按钮之前所有单选按钮和复选按钮的最终状态（这也会破坏窗口）。有人知道如何将这些值写到变量矩阵中，以便在窗口被破坏后可以正常工作？

我尝试创建一个变量：final = [var.get（），var1.get（），var2.get（），get_noise_scan（），get_power_scan（）]，以便在销毁窗口之前获取值但这不起作用。

import tkinter as tk
from tkinter import ttk 


window = tk.Tk()
window.configure(background='white')
window.geometry("500x600") # This sets the Window size to work with
window.title('Please select scan options')


comp = [('BRF','Orange'), ('SHG','Green') ,('THG','Purple'), ('ETA','Blue'), ('MAIN TEC', 'Red')]

def get_noise_scan():
    n = noise_scan.get()
    print(n)
    return n

def get_power_scan():
    p = power_scan.get()
    print(p)
    return p

############
power_scan = tk.StringVar()
check1 = tk.Checkbutton(window, text='Get power', 
        command=get_power_scan, variable = power_scan ,
        onvalue="Yes", offvalue="No")

check1.place(x=400,y=50)
check1.deselect()
#############
noise_scan = tk.StringVar()
check2 = tk.Checkbutton(window, text='Get noise', 
        command=get_noise_scan, variable = noise_scan ,
        onvalue="Yes", offvalue="No")

check2.place(x=400,y=100)
check2.deselect()

if power_scan.get() == "Yes" :
    # do something
    print("Power scan selected")

button = tk.Button(window, font="Heltavica",text ="PROCEED", command=get_scan)
button.config(bd=8, font="Ariel", justify="center")

window.mainloop()

Answer 1

最简单的方法是为列表global声明final：

...

def get_scan():
    global final
    print(var.get(),var1.get(),var2.get(),get_noise_scan(),get_power_scan())
    final = [var.get(),var1.get(),var2.get(),get_noise_scan(),get_power_scan()]
    window.destroy()

...

window.mainloop()

print (final)

结果：

['', '', 'ETA', 'No', 'No']

在销毁窗口时获取所有单选按钮和复选框的最终状态
