Constructor Detail

GUI

public GUI()

Creates new form GUI.
First Constructor gets the default screensize from awt.Toolkit.class and then build the current GUI frame size with call of the setsize(x,y) method and centers it with call of setLocation().

After that the VoteProcessor is initialised and also the initComponents() method. Finally the GUI is setVisible().

See Also:

VoteProcessor.VoteProcessor(GUI), initComponents(), Go to Code

Method Detail

initComponents

private void initComponents()

This method is called from within the constructor to initialize the form. It is also responsible for position and putting ActionListener to form elements.

WARNING: Do NOT modify this code. The content of this method is always regenerated by the Form Editor.

loadBallotFile

private void loadBallotFile(java.awt.event.ActionEvent evt)

load the ballot file.

EPC Main_process 10: First this method loads the ballot file via the setVotes(String) method, the path to file captures the method from jTextField3. After that the vote file will be checked and loaded with the CheckVoteFile() method. If true the jLabel3 is set to "file loaded" else mentioned method will do error handling.

startProcessing

private void startProcessing(java.awt.event.ActionEvent evt)

this method starts the evaluation process.

EPC Main_process 14: This method starts the evaluation process with click of jButton1. First it will be checked if key- and ballot file are set and have no errors. This will be done with help of the checkKeyFile() and CheckVoteFile() method.

If both are true the process will be started via the doProcessing() method. Key and ballot file are absolutely necessary because even if no calculation has to be done, keys are needed for decryption.

EPC Main_process 36: After processing - if no process stoping errors are occured (checked with the getShowTable() method)- the result will be shown in a Table. Please check the TableFrame class for more details.
