size of each advanced command is variable, so it can be either greater or equal to 1. In
the first case, the payload value is parsed from a textfield as in the first two rows. The Set
button is used to send the command in this respect. In the second case, the payload value
(On/Off states) is set and the command is sent, by a “Press” action of the corresponding
On/Off buttons. The total number of the advanced commands in this tab is based on the
CSV file and is completely dynamic. Using this feature, the developers of the FPGA can
add/remove new commands in the file and reload the client updated.
4.4.6.1 Design implementation of the commands interfaces
The two commands displays are developed around two main classes and an auxiliary one.
The static commands tab is implemented by a class named StaticCommandsGUI. This
class responsibility is to create the static commands tab interface, as well as implement
action listeners for the different elements inside the interface. The auxiliary class named
Commands, implements the separate construction of each command. The commands
are sent via the TCP socket to the server after construction. A “Set” action by the user is
required to fire the code for constructing and sending the corresponding command inside
an action listener. The other main class, used for the creation of the Advanced commands
tab, is called GUIScalarElement. This class is used only in case a suitable CSV file is
present in the project’s resources. Firstly, it parses the CSV file and sets its fields with the
required information. Finally, an ArrayList, which contains all the Advanced commands
rows as elements, is returned by dedicated methods and manipulated properly.
