Client Code Flow (Draft)

Topics

• Handles the TCP connection and sending data
• Listens for user input from STDIN using notifier

---

Flow

1. The client is created.

   • Creating a notifier for user inputs
   • A socket notifier is set up on STDIN (read events).
   • connecting TCP socket connection signals to slots for debugging and recovery
   • connecting TCP socket data ready signal to onServerResponse slot
   • connecting notifier signal to onUserInput slot

2. The client attempts to connect to the server.

   • Server address is set to localhost and the port is taken from common.h.

3. The onUserInput slot

   • reads a line.
   • sends it to the Server using sendData method.

4. The sendData method

   • if connected, send command directly to Server.
   • else, buffer the command into the Queue and try to connect again.
   • Once connected, any buffered commands are flushed and sent in order.
