How can I communicate with other client connections on a MySQL server using python? I have multiple computers running python applications, each using the same MySQL server. Each of the applications contains a tkinter GUI that allows editing of a set of data (corresponding to data in a table in the MySQL server). Whenever the data is updated one machine (and in turn updated on the MySQL server), I would like the other machines to be prompted to update there displayed data by pulling from the server. I know I could simply have the applications self-update after a given interval, but I would prefer to only update when there is new data to pull.

The objective is when a client sends a message to the server, the server just sends that message back to all the other clients. I had the server send a message writen by him send to all the clients but he didn't send the clients message. Server code: package Group; import java.net.*; import java.io.*; import java.util.ArrayList; import java.util.Collections; import java.util.List; import java.util.logging.*; public class GroupServer extends Thread { private ServerSocket server; protected List<ClientHandler> clients; public static void main(String args) throws IOException { new GroupServer(9876); } public GroupServer(int port) { try { this.server = new ServerSocket(port); System.out.println("New server initialized!"); clients = Collections.synchronizedList(ne...
