How to capture the data entered in a textfield in a JTable

Question

How to capture the data entered in a textfield present in a cell of a textfield or how to add listener to this textfield

Answer 1

A sample of my code is:
          model = new GridDisplayTableModel(gridDisp,columnName,getRows(),getCols());
          final ComboRenderer cRenderer = new ComboRenderer();
          final TextFieldRenderer tRenderer = new TextFieldRenderer();
          combo.addItem("one");
          combo.addItem("two");
          combo.addItem("three");
          final JTextField textfield = new JTextField();
          final DefaultCellEditor cmbEditor = new DefaultCellEditor(combo);
     //     final JEnterDataCellEditor textEditor = new JEnterDataCellEditor(12);
          final DefaultCellEditor textEditor = new DefaultCellEditor(textfield);
          rm = new RowEditorModel();
          table = new JTable(model){
     public TableCellRenderer getCellRenderer(int row, int column) {
          int posx = 0;
               int posy = 0;
               TableCellRenderer renderer = null;
     for(int l=0;l<getDataVec().size();l++)
               beanObj =(Helperbean)dataVec.elementAt(l);
               posx = beanObj.getPosx();
               posy = beanObj.getPosy();
               if(row==posx && column==posy)
                         if(beanObj.getModeofDisplay() != null && beanObj.getModeofDisplay().equalsIgnoreCase("textfield"))
                              rm.addEditorForRow(row,textEditor);
                              renderer = tRenderer;
                         else if(beanObj.getModeofDisplay() != null && beanObj.getModeofDisplay().equalsIgnoreCase("combo"))
                              rm.addEditorForRow(row,cmbEditor);
                              renderer = cRenderer;
                         break;
                    renderer = super.getCellRenderer(row, column);
          //     System.out.println("getEditor"+rm.getEditor(1));
     return renderer;
public TableCellEditor getCellEditor(int row, int col) {   
     int posx = 0;
     int posy = 0;
     TableCellEditor tmpEditor = null;
for(int l=0;l<getDataVec().size();l++)
     beanObj =(Helperbean)dataVec.elementAt(l);
     posx = beanObj.getPosx();
     posy = beanObj.getPosy();
     if(row==posx && col==posy)
               if(beanObj.getModeofDisplay() != null && beanObj.getModeofDisplay().equalsIgnoreCase("textfield"))
                    System.out.println("celleditorval "+textEditor.getCellEditorValue());
                    tmpEditor = textEditor;
               else if(beanObj.getModeofDisplay() != null && beanObj.getModeofDisplay().equalsIgnoreCase("combo"))
                    tmpEditor = cmbEditor;
               break;
          tmpEditor = super.getCellEditor(row, col);
return tmpEditor;
public boolean isCellEditable(int row,int col){
     boolean isEditable = false;
     int posx = 0;
     int posy = 0;
for(int l=0;l<getDataVec().size();l++)
     beanObj =(Helperbean)dataVec.elementAt(l);
     posx = beanObj.getPosx();
     posy = beanObj.getPosy();
     if(row==posx && col==posy)
          if(beanObj.getModeofDisplay() != null )     
                    isEditable = true;     
               else
                    isEditable = false;     
               break;
     isEditable = false;
     return isEditable;
public void changeSelection(final int row, final int column, boolean toggle, boolean extend) {
     super.changeSelection(row, column, toggle, extend);
     //my attempt to avoid editCellAt from being called twice in a row
     if (getModel().isCellEditable(row, column) && !(isEditing() && getEditingRow() == row && getEditingColumn() == column))
          if (editCellAt(row, column)) {
               getEditorComponent().requestFocus();
     // Select the text when the cell starts editing
public boolean editCellAt(int row, int column) {       
     boolean result = super.editCellAt(row, column);
     final Component editor = getEditorComponent();
     if (editor != null && editor instanceof JTextField) {           
          SwingUtilities.invokeLater(new Runnable() {               
               public void run() {                   
                    ((JTextField)editor).selectAll();
          return result;
     public boolean hasFocus()
          Component editorComponent = getEditorComponent();
          // Try to install the editor
          int anchorRow = getSelectionModel().getAnchorSelectionIndex();
          int anchorColumn = getColumnModel().getSelectionModel().
          getAnchorSelectionIndex();
          if (anchorRow != -1 && anchorColumn != -1 && !isEditing())
          if ((this.getSelectedRow() == anchorRow) && (this.getSelectedColumn() == anchorColumn))
          if (!editCellAt(anchorRow, anchorColumn)) {}
          return super.hasFocus();
     public void valueChanged(ListSelectionEvent e)
          super.valueChanged(e);
          if ((this.getSelectedRow() == 2) && (this.getSelectedColumn() == 3))
               DefaultFocusManager focusManager = new DefaultFocusManager();
               focusManager.focusNextComponent(this);
               model.fireTableStructureChanged();
