I have problem with updating progressbar. If I check checkbox, file is automaticaly copied but progress is still 0. I use SwingWokrer, but I don't know how I can progressbar updating.
I tried many combinations, but it does not work.

This code is responsible for downloading the file from the selected row.

 jTable.getModel().addTableModelListener(new TableModelListener() 
 public void tableChanged(TableModelEvent e) 
 int row = e.getFirstRow();
 int column = e.getColumn();
 TableModel tableModel = (TableModel) e.getSource();

 Boolean dataObject = (Boolean) tableModel.getValueAt(row,column);
 String fileNameToCopy = (String) tableModel.getValueAt(row, 0);
 Long fileSize = (Long) tableModel.getValueAt(row, 1);
 Float progress = (Float) tableModel.getValueAt(row, 3);

 if (dataObject == true) 
 customTableData.setFile(new File(fileNameToCopy));
 customTableData.setFileSize(fileSize);
 customTableData.setProgress(progress);;
 copyFiles = new CopyFiles(customTableData);
 

 
 );

CustomTableData.java

public class CustomTableData 

private File file;
private long fileSize;
private Boolean edit = false;
private float progress;

public CustomTableData() 

public File getFile() 
 return file;

public void setFile(File file) 
 this.file = file;


public long getFileSize() 
 return fileSize;


public void setFileSize(long fileSize) 
 this.fileSize = fileSize;


public Boolean isEdit() 
 return edit;


public void setEdit(Boolean edit) 
 this.edit = edit;


public float getProgress() 
 return progress;


public void setProgress(float progress) 
 this.progress = progress;

My CopyFiles.java class

private String fileName;
private long fileSize;
private float progress;
private CustomTableData data;

public CopyFiles(CustomTableData data) 
 this.data = new CustomTableData();
 this.fileName = data.getFile().getName();
 this.fileSize = data.getFileSize();
 this.progress = data.getProgress();
 worker.execute();


SwingWorker<Void, Float> worker = new SwingWorker<Void, Float>()

 @Override
 protected Void doInBackground() throws Exception 


 InputStream is = null;
 OutputStream os = null;
 try 
 is = new FileInputStream(source + fileName);
 os = new FileOutputStream(destination + fileName);
 byte buffer = new byte[BUFFER];
 int length = 0;
 float pro = 0;
 while((length = is.read(buffer)) != -1) 
 publish(pro += length);
 os.write(buffer, 0, length);
 
 catch (Exception e) 
 e.getMessage();
 finally 
 try 
 is.close();
 os.close();
 catch (IOException e) 
 e.getMessage();
 
 
 return null;
 

 protected void process(java.util.List<Float> chunks) 
 for (Float f : chunks) 
 progress = (f*100) / fileSize;
 System.out.println("Percentage progress: " + progress + " >>> file size: " + f);
 
 ;

 protected void done() 
 System.out.println("FILE: " + fileName + " SIZE: " + fileSize);
 ; 
;
}

And my CustomTableModel.java class

public class CustomTableModel extends AbstractTableModel 

private static final long serialVersionUID = -2929662905556163705L;

@SuppressWarnings("unused")
private File dir;
private File fileArray;
private List<CustomTableData> filesList;
private CustomTableData fileRow;

public CustomTableModel(File dir) 
 this.dir = dir;
 this.filesList = new ArrayList<CustomTableData>();
 this.fileArray = dir.listFiles();
 fileLoop();


private void fileLoop() 
 for (int i = 0; i < fileArray.length; i++) 
 this.fileRow = new CustomTableData();
 if (fileArray[i].isFile()) 
 fileRow.setFile(fileArray[i]);
 fileRow.isEdit();
 fileRow.getProgress();
 filesList.add(fileRow);
 
 


private ResourceBundle resourceBundle = ResourceBundle.getBundle("MessageBundle", Locale.forLanguageTag("pl"));

protected String columns = new String 
 resourceBundle.getString("fileName"),
 resourceBundle.getString("fileSize") + " [byte]",
 resourceBundle.getString("getFile"),
 resourceBundle.getString("progress");


@SuppressWarnings("rawtypes")
protected Class columnClasses = String.class , Long.class, JCheckBox.class, JProgressBar.class;

public int getColumnCount() 
 return columns.length;


public int getRowCount() 
 return filesList.size();


public String getColumnName(int col) 
 return columns[col].toString();


public Class<?> getColumnClass(int c) 
 switch (c) 
 case 0:
 return String.class;
 case 1:
 return Long.class;
 case 2:
 return Boolean.class;
 case 3:
 return Float.class;
 default:
 return null;
 


public Object getValueAt(int row, int col) 
 fileRow = filesList.get(row);

 switch (col) 
 case 0:
 return fileRow.getFile().getName();
 case 1:
 return fileRow.getFile().length();
 case 2:
 return fileRow.isEdit();
 case 3:
 return fileRow.getProgress();
 default:
 return null;
 


public boolean isCellEditable(int row, int col) 
 switch (col) 
 case 0:
 return false;
 case 1:
 return false;
 case 2:
 return true;
 case 3:
 return false;
 default:
 return false;
 
 

public void setValueAt(Object aValue, int row, int column) 
 fileRow = filesList.get(row);
 if (column == 2) 
 fileRow.setEdit((Boolean)aValue);
 fireTableCellUpdated(row, column);
 

This is my ProgressBarRenderer.java class

public class ProgressBarRenderer extends JProgressBar implements TableCellRenderer 

private static final long serialVersionUID = 551156559687881082L;

public ProgressBarRenderer() 
 super();


public ProgressBarRenderer(int min, int max) 
 super(min, max);


public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) 

 setValue((int) ((Float) value).floatValue());

 return this;

My table view

Rozwiązanie

Progressbar jest prawidłowo aktualizowany w metodzie process()

public class CopyFiles {

private static final int BUFFER = 1024;

private int row;
private CustomTableModel customTableModel;

private String fileName;
private File file;

public CopyFiles(String fileName, CustomTableModel customTableModel, int row) 
 this.fileName = fileName;
 this.file = new File(PathEnum.SOURCE.getPath() + fileName);
 this.customTableModel = customTableModel;
 this.row = row;
 worker.execute();


public String getFile() 
 return file.getName();


public long getFileSize() 
 return file.length();


public SwingWorker<Void, Float> getWorker() 
 return worker;

 SwingWorker<Void, Float> worker = new SwingWorker<Void, Float>() 

 @Override
 protected Void doInBackground() throws Exception 

 InputStream is = null;
 OutputStream os = null;

 float progress = 0;
 try 
 is = new FileInputStream(PathEnum.SOURCE.getPath() + getFile());
 os = new FileOutputStream(PathEnum.DESTINATION.getPath() + getFile());

 byte buffer = new byte[BUFFER];

 long count = 0;
 int bufferLength;

 while ((bufferLength = is.read(buffer)) != -1) 
 count += bufferLength;
 os.write(buffer, 0, bufferLength);

 progress = (int) ((count * 100) / getFileSize());
 publish(progress);
 
 catch (Exception e) 
 e.getMessage();
 finally 
 try 
 is.close();
 os.close();
 catch (IOException e) 
 e.getMessage();
 
 
 return null;
 

 protected void process(List<Float> chunks) 
 float currentProgress = chunks.get(chunks.size()-1);
 customTableModel.setValueAt(currentProgress, row, 3);
 ;

 protected void done() 
 System.out.println("FILE: " + getFile() + " SIZE: " + getFileSize());
 ;
