Detailed Description

Creates a Thread to read input data, and a QTcpSocket to dialog with the server.

Usage

The default port used for connection is 4242

In the input:

• lines starting by '#' are treated as comments
• lines starting by ':' are treated by the client
• line starting by ':!' signals the end of file
• line starting by ':D' signals the client to echo the comments
• line starting by ':d' signals the client not to echo the comments
• line starting by ':X' stops the client

• otherwise a line contains commands separated by ':'
• commands may contain arguments separated by ';'

When reading from the server

• lines starting with ! are commands
• lines starting by : are diplayed in the text window otherwise they are output to the terminal
