如何检查按钮是否有效

Question

我知道“ip”有效，但是当我点击按钮时，我什么也看不到（用户应该什么也看不到，所以这太棒了！）但是，我不知道如何验证按钮的能力. 目标是最终将指定的信息从按钮发送到标签小部件（用户将看到）

import tkinter as tk
import subprocess


ip = subprocess.run("ipconfig /all",universal_newlines=True,
                       stdout=subprocess.PIPE,
                       stderr=subprocess.PIPE)


#Setup for the window
window =tk.Tk()
window.title("Title_Name")
window.geometry("300x500")
x = window.winfo_x()
y = window.winfo_y()
sh = window.winfo_screenheight()
sw = window.winfo_screenwidth()
x_cord = int((sw/2)-550)
y_cord = int((sh/2)-300)
wh = 350
ww = 500
window.geometry("{}x{}+{}+{}".format(ww, wh ,x_cord, y_cord))



#widgets
button = tk.Button(window, text= "submit",
                   command = ip)

#widget placement
button.grid(row=0, column=0, padx=5)

只需快速将命令更改为不同的函数来测试命令！

import tkinter as tk
import subprocess


ip = subprocess.run("ipconfig /all",universal_newlines=True,
                       stdout=subprocess.PIPE,
                       stderr=subprocess.PIPE)


#Setup for the window
window =tk.Tk()
window.title("Title_Name")
window.geometry("300x500")
x = window.winfo_x()
y = window.winfo_y()
sh = window.winfo_screenheight()
sw = window.winfo_screenwidth()
x_cord = int((sw/2)-550)
y_cord = int((sh/2)-300)
wh = 350
ww = 500
window.geometry("{}x{}+{}+{}".format(ww, wh ,x_cord, y_cord))

def ButtonTest():
   print('The button is working!')

#widgets
button = tk.Button(window, text= "submit",
                   command = ButtonTest)

#widget placement
button.grid(row=0, column=0, padx=5)

tk.mainloop()

当您运行此代码并按下按钮时，它将打印输出，因此您可以放心，假设 ip 函数正常工作，它将运行!
