*Using python tkinter I need help with a chat system to run between two users who connect to the server, I know how to make it work by running multiple client windows on 127.000 local host but how would multiple users running the GUI then be able to connect to a different server ip to chat in real time between different computers.

Let's say I have a GUI screen built , how would I add a button to the screen and upon clicking the button, it opens another window for a chat messenger and is able to chat to another person connected to the server?

This is what I have for the server side but it only works for the local user. I also need help to add a button to a main window and upon clicking it opens the chat/client side.

# Import required modules import socket import threading # server ip address HOST = '127.0.0.1' PORT = 1234 # any port between 0 and 65535 LISTENER_LIMIT = 5 active_clients = [] # List of all currently connected users # Function to listen for upcoming messages from a client def listen_for_messages(client, username): while 1: message = client.recv(2048).decode('utf-8') if message != '': final_msg = username + '~' + message send_messages_to_all(final_msg) else: print(f"The message send from client {username} is empty") # Function to send message to a single client def send_message_to_client(client, message): client.sendall(message.encode()) # Function to send any new message to all the clients that # are currently connected to this server def send_messages_to_all(message): for user in active_clients: send_message_to_client(user[1], message) # Function to handle client def client_handler(client): # Server will listen for client message that will # Contain the username while 1: username = client.recv(2048).decode('utf-8') if username != '': active_clients.append((username, client)) prompt_message = "SERVER~" + f"{username} added to the chat" send_messages_to_all(prompt_message) break else: print("Client username is empty") threading.Thread(target=listen_for_messages, args=(client, username,)).start() # Main function def main(): # Creating the socket class object # AF_INET: IPv4 addresses server = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # Creating a try catch block try: # Provides the server with an address in the form of # host IP and port server.bind((HOST, PORT)) print(f"Running the server on {HOST} {PORT}") except: print(f"Unable to bind to host {HOST} and port {PORT}") # Set server limit server.listen(LISTENER_LIMIT) # This while loop will keep listening to client connections while 1: client, address = server.accept() print(f"Successfully connected to client {address[0]} {address[1]}") threading.Thread(target=client_handler, args=(client,)).start() if __name__ == '__main__': main() # Run server side script by opening terminal/command prompt and cd to project directory and type: python server.py 

Here is the code for the client side below . Aside from editing code to be able to run on different server between to computers, I need to add a button to the main window that opens this chat interface.
