基于qt的网络聊天室，可实现多客户端同时登陆，服务端监视客户端的聊天信息等，还可客户端和客户端之间发送文件。-Qt-based chat rooms, multi-client while landing, server monitoring client chat messages, etc., but also between the client and the client to send the file.

实现windows跟Ubuntu两个平台的聊天及发送文件-this programme is for windows and ubuntu to chat and transfer, surely, we can make them to chat between windows and arm-based pad.
