I want to Print my output on pop up window? how should I approach?

Question

import tkinter as tk
import datetime 

def write_slogan():
    dt_object = datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")
    print("OrderName: %s"%dt_object)


master = tk.Tk()
tk.Button(master, 
          text='ORDER Number', 
          command=write_slogan).grid(row=3, 
                                    column=1, 
                                    sticky=tk.W, 
                                    pady=4)

tk.mainloop()

How should I print the above code outputs on the pop-up window rather than terminal?

Answer 1

Print message inside tkinter window rather than terminal

If you just want to print the message in the root window, you can use a label widget like this in the following code:

import tkinter as tk

master = tk.Tk()

def write_slogan():
    info_message = "Your message"
    tk.Label(master, text=info_message).grid(row=2, column=1) 

btn = tk.Button(master, text='ORDER Number', command=write_slogan)
btn.grid(row=3, column=1, sticky=tk.W, pady=4)

master.mainloop()

Print message in a separate pop-up window

You can use a message box from the tkinter messagebox module to pop up some info with your info message displayed in it.

import tkinter as tk
import tkinter.messagebox as tkmb

def write_slogan():
    info_message = "Your message"
    # info message box
    tkmb.showinfo("Output", info_message)

master = tk.Tk()

btn = tk.Button(master, text='ORDER Number', command=write_slogan)
btn.grid(row=3, column=1, sticky=tk.W, pady=4)

master.mainloop()

Creating a toplevel window as a pop up window

import tkinter as tk
import tkinter.messagebox as tkmb

def write_slogan():
    # toplevel window
    top_win = tk.Toplevel(master)
    top_win.title('Toplevel')
    info_message = "Your message"
    # info message box
    tk.Label(top_win, text=info_message).grid(row=0, column=0) 

master = tk.Tk()
master.title('Master')

btn = tk.Button(master, text='ORDER Number', command=write_slogan)
btn.grid(row=3, column=1, sticky=tk.W, pady=4)

master.mainloop()
