= The Socket =
==Modify the Project File==
The first thing to do is add ''networking'' to the project file, so that Qt knows that we wanna work with the network model.

==The Client==

The orderman socket uses the class [http://qt-project.org/doc/qt-5.1/qtnetwork/qtcpsocket.html QTcpSocket] to communicate with the FOS server. The function ''connect()'' connects the application socket to the FOS server on login. If the communication fails the user will be asked to set the right port. The application settings and an explanation how to set the correct port will be shown. The user will also be advertised to turn on wifi.

When the waiter starts the orderman the application has to find out the ip adress and the port which allows the communication with the server. The port is set in the application settings and must correspond to the FOS server port specified in the server settings. The class [http://qt-project.org/doc/qt-5.1/qtnetwork/qnetworkconfigurationmanager.html#details QNetworkConfiguration] provides access to the network configurations known to the system and allows to find out the router port with the function [http://qt-project.org/doc/qt-5.1/qtnetwork/qnetworkconfigurationmanager.html#allConfigurations allConfigurations]().

The function ''send()'' sends the JSON objects to the server. When the signal ''readyRead()'' is emitted by the server it means that the server sent back a JSON object.

The socket will be closed when the waiter logs out.

= Android Permissions =
The order man application must have the appropriate permissions that allow the connection to the server. An important permission to do that is the [http://developer.android.com/reference/android/Manifest.permission.html#INTERNET INTERNET] permission, which allows applications to open network sockets.
