I am working on a school project where I made a GUI Reminder application using customTkinter module and mysql database with two tables named user and reminder.

user Table will contain data like this user Table Structure

reminder table will contain data like this reminder table structure

THE CODE IS Updated

The code is given below:

Now I want to run showreminder repeatedly in the background without affecting the GUI and it must run on Windows 10/11.

I tried to use the schedule module but it did not get executed, and I tried to put the whole code in while loop. It did work but other function where not usable until the reminder came.

CodePudding user response：

Whenever you want to perform two or more operations in parallel use threading module

import threading

def showreminder():
    # define your function

def showreminder_threaded():
    thread = threading.Thread(target = showreminder())
    thread.start()

Instead of calling showreminder() call showreminder_threaded(), then it will run parallelly

CodePudding user response：

After reading all of your suggestion and tinkering around I found that this code made helped what I want to accomplish

def call_showreminders():
     current_time = datetime.now().strftime("%S")
     if current_time == "00":
        showreminder()
        window.after(1000, call_showreminders)  # call call_showreminders every second
window.after(1000, call_showreminders)
window.mainloop()
