Basic network communication example with QTcpSocket, QUdpSocket, and QTcpServer.

A Qt project that supports listening to messages over socket.

• The IP Address and Port Number are runtime input from the user. Send messages to any IP-port combination.

  • The message to send is an input from a textEdit box.

• Supports both TCP and UDP communications.

• Also contains functionality to create a Server.

  • Listens to both UDP messages as well as TCP message simultaneously. (priority to TCP - keeps reading while bytesAvailable)
  • You can view the last 10 messages sent to the server in a QMessageBox.

• UI/UX is bae.

• WYSIWYG - check out the Gallery to see what it does.

• Open the .pro file from within Qt Creator
• Run the project
• Disable the last line within the .pro file to get qDebug() statements in a separate console window.

• The UDP connection happens over a single QUdpSocket right now. Need to look into improving the implementation with two sockets instead of just one.
