如何使用tkinter在我的窗口中创建实时更新的提要

Question

我需要得到一个单独的窗口的一部分，以输出文本的基础上发生了什么，例如，4电子邮件发送将如下所示:发送...成功:已发送电子邮件！成功:已发送电子邮件！成功:已发送电子邮件！成功:已发送电子邮件！所有4封电子邮件都已成功发送！

import smtplib
from tkinter import *

root = Tk()

root.title("Inbox Flooder")
root.geometry("720x520+0+0")
root.configure(background="black")

def click():
    global YOUR_EMAIL_ADDRESS , YOUR_PASSWORD , AMNT_REPEAT , TARGET_EMAIL , subject , msg
    YOUR_EMAIL_ADDRESS=YOUR_EMAIL_ADDRESS.get()
    YOUR_PASSWORD=YOUR_PASSWORD.get()
    TARGET_EMAIL=TARGET_EMAIL.get()
    subject=subject.get()
    msg=msg.get()
    AMNT_REPEAT=AMNT_REPEAT.get()
    print("Starting...")    

while int(AMNT_REPEAT) > 0 :
    send_email(subject, msg)
    AMNT_REPEAT = int(AMNT_REPEAT) - 1

if failed > 0 and sent > 0 :
    print(sent,"email(s) have been sucessfully sent and",failed ,"emails have failed to send.")

if failed > 0 and sent == 0 :
    print("All",failed ,"emails have failed to send.")

if failed == 0 and sent > 0 :
    print("All",sent ,"emails have sucessfully been sent!")


def send_email(subject, msg):
    global sent , failed
    try:
        server = smtplib.SMTP('smtp.gmail.com:587')
        server.ehlo()
        server.starttls()
        server.login(YOUR_EMAIL_ADDRESS, YOUR_PASSWORD)
        message = 'Subject: {}\n\n{}'.format(subject, msg)
        server.sendmail(TARGET_EMAIL, TARGET_EMAIL, message)
        server.quit()
        print("Sucess: Email sent!")
        sent = sent + 1

    except:
        print("Error: Email failed to send.")
        failed = failed + 1

def close_window():
    try:
        root.destroy()
        exit()

    except:
        print("Tab Closed")

下面是一个简单的程序，它在窗口打开时循环，添加“成功:发送电子邮件！”这只不过是演示如何向基本的tkinter GUI添加内容。

然而，你将需要使用线程，因为你的发送应该在窗口打开时在后台执行，这将需要一些适当的研究，我不会在这里解释这个过程(另一个线程应该很容易找到)。

import tkinter as tk

def send_success():
    # Allow us to insert into the widget
    logt.config(state="normal")
    # Insert into the widget (adding a newline at the end)
    logt.insert("end", "Success: Email sent!\n")
    # Disable user changes again
    logt.config(state="disabled")
    # Scroll to bottom of widget (to show new text)
    logt.see("end")
    # Schedule a call to ourselves after 1 second
    root.after(1000, send_success)

# Create the main tkinter window
root = tk.Tk()

# Create our text widget (normally a multi-line text
# entry widget, but this will be our log widget)
logt = tk.Text(root)
# Add the widget to the window
# (and set it to increase in size with the window)
logt.pack(side="left", fill="both", expand=True)
# Stop people changing the content
logt.config(state="disabled")

# Create a vertical scrollbar
sc = tk.Scrollbar(root)
# Add the widget to the window
sc.pack(side="right", fill="y")
# Move the text widget when scrollbar moved
sc.config(command=logt.yview)
# Change scrollbar length when new content added
logt.config(yscrollcommand=sc.set)

# Schedule our method to run once the mainloop is running
root.after(0, send_success)

# Run the mainloop
# This handles window actions (moving, resizing, etc.)
root.mainloop()
