Thread: netbeans JTable Jbutton

I went through many links on the internet for Jtable Button ! since I am lil good with C# i thought It will be easy to switch to JAVA but I am having a hard time in solving one problem and I can do core Java and netbeans JDBC stuff but I don't understand how to append core java into netbeans ! It seems that core JAVA and netbeans JAVA coding methods differs

I went through this coding which is in Java2SS site
Button Table Example : Grid TableSwing ComponentsJava


how to use this code for a netbeans project pls share ur ideas !

((DefaultTableModel)JTable.getModel()).getColumnName(0).r....

I tried to use the aboce code but it gives me many errors !!! pls help

 initComponents();
 
//DefaultTableModel dm = new DefaultTableModel();
 
//dm.setDataVector(new Object[][]{{"button 1", "foo"}, {"button 2", "bar"}}, new Object[]{"Button", "String"});
 
 jTable1.getColumn("Button").setCellRenderer(new ButtonRenderer());
 
 jTable1.getColumn("Button").setCellEditor(new ButtonEditor(new JCheckBox()));
 
((DefaultTableModel)jTable1.getModel()).addRow(new Object[] {"NX1001","Product name","Delete"});

outPut :



1. but I don't want the empty records ! I only need the last record which I added ?


2. I assume tht the below function is the one which triggers or acts as a event ! how to get the row[0] value when the delete button is clicked

  public ButtonEditor(JCheckBox checkBox) {
    super(checkBox);
    button = new JButton();
    button.setOpaque(true);
    button.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
        fireEditingStopped();
      }
    });
  }

There were some coding errors I managed to solve'em and btw thx alot 4 replying !

  public Component getTableCellRendererComponent(JTable table, Object value,
                   boolean isSelected, boolean hasFocus, int row, int column) {
    if (isSelected) {
      setForeground(table.getSelectionForeground());
      setBackground(table.getSelectionBackground());
    } else{
      setForeground(table.getForeground());
      setBackground(UIManager.getColor("Button.background"));
    }
    setText( (value ==null) ? "" : value.toString() );
    return this;
  }
}
class ButtonEditor extends DefaultCellEditor {
  protected JButton button;
  private String    label;
  private boolean   isPushed;
 
  public ButtonEditor(JCheckBox checkBox) {
    super(checkBox);
    button = new JButton();
    button.setOpaque(true);
    button.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
        fireEditingStopped();
      }
    });
  }
 
    @Override
  public Component getTableCellEditorComponent(JTable table, Object value,
                   boolean isSelected, int row, int column) {
    if (isSelected) {
      button.setForeground(table.getSelectionForeground());
      button.setBackground(table.getSelectionBackground());
    } else{
      button.setForeground(table.getForeground());
      button.setBackground(table.getBackground());
    }

    button.setText( label );
    isPushed = true;
    return button;
  }

    if (isPushed)  {
[COLOR="Red"]      //
      //
      JOptionPane.showMessageDialog(button ,label + ": Ouch!");
      // System.out.println(label + ": Ouch!");[/COLOR]
    }
    isPushed = false;
    return new String( label ) ;
  }
 
    @Override
  public boolean stopCellEditing() {
