QtWidgets Instant Chat Application (Client/Server)

This is a simple instant messaging application built with QtWidgets. It demonstrates a basic client-server architecture, allowing users to send and receive text messages in real-time over a network. The client communicates with the server to exchange messages.

Features

• Real-time messaging: Multiple clients can send and receive messages instantly through the server.
• Client-server communication over TCP/IP: Clients connect to the server via the server’s IP address.
• Chat window with input and output areas: The user interface includes a text area to display chat messages and an input box to type messages.
• Message history: The chat window displays the history of messages.
• Client status management: Clients can change their online status (None, Availabe, Away, Busy).
• Server events broadcasting:
  • Client typing detection: The server broadcasts when a client is typing.
  • Client connection/disconnection: The server detects when a client connects or disconnects and broadcasts the event to other clients.
  • Client name change: The server detects when a client changes their username and notifies other clients.
• Server-initiated messages: The server can send messages to any connected clients.
