Dynamically create n-column and n-rows forms in awt/swing

Hi

I'm newbie on this forum.
I have no idea how code events when dynamically generate form with n-columns and n-rows.

I explaine it on short example code:

Code:

---

for (int i = 1; i <= array.size(); i++) {
    JSONObject obj_i = (JSONObject) array.get(i);
    int idd = Integer.valueOf(obj_i.get("id").toString());
    int weight = Integer.valueOf(obj_i.get("weight").toString());
 
    if (Boolean.valueOf(obj_i.get("checkbox").toString())) {
        final JCheckBox chkbx_suffix_idd_i;
 
        switch (weight) {
        case 0:
            chkbx_suffix_idd_i =  new CheckBox(obj_i.get("desc").toString());
            chkbx_suffix_idd_i.setFont(new Font("Dialog", Font.BOLD, 13));
            break;
        case 1:
            chkbx_suffix_idd_i =  new JCheckBox("  " + obj_i.get("desc").toString());
            chkbx_suffix_idd_i.setFont(new Font("Dialog", Font.PLAIN, 12));
            break;
        case 2:
            chkbx_suffix_idd_i =  new JCheckBox("    " + obj_i.get("desc").toString());
            chkbx_suffix_idd_i.setFont(new Font("Dialog", Font.PLAIN, 12));
            break;
        default:
            chkbx_suffix_idd_i =  new JCheckBox(obj_i.get("desc").toString());
            chkbx_suffix_idd_i.setFont(new Font("Dialog", Font.PLAIN, 12));
            break;
        }
 
        chkbx_suffix_idd_i.setToolTipText("Kliknięcie spowoduje rozwinięcie pola o pozycje bardziej szczegółowe.");
        GridBagConstraints gbc_chkbx_suffix_idd_i = new GridBagConstraints();
        gbc_chkbx_suffix_idd_i.anchor = GridBagConstraints.WEST;
        gbc_chkbx_suffix_idd_i.insets = new Insets(0, 0, 5, 5);
        gbc_chkbx_suffix_idd_i.gridx = 0;
        gbc_chkbx_suffix_idd_i.gridy = i;
        chkbx_suffix_idd_i.addItemListener(new ItemListener() {
            public void itemStateChanged(ItemEvent arg0) {
                if (chkbx_suffix_idd_i.getSelectedObjects() != null) {
                      chkbx_suffix_idd_i.setVisible(true);
                } else {
                      chkbx_suffix_idd_i.setVisible(false);
                }
            }
        });
        panel.add(chkbx_suffix_idd_i, gbc_chkbx_suffix_idd_i);
  } else {
  final JLabel lbl_suffix_idd_i;
 
  switch (weight) {
      case 0:
          lbl_suffix_idd_i = new JLabel(obj_i.get("desc").toString());
          lbl_suffix_idd_i.setFont(new Font("Dialog", Font.BOLD, 13));
          break;
      case 1:
          lbl_suffix_idd_i = new JLabel("      " + obj_i.get("desc").toString());
          lbl_suffix_idd_i.setFont(new Font("Dialog", Font.PLAIN, 12));
          break;
      case 2:
          lbl_suffix_idd_i = new JLabel("          " + obj_i.get("desc").toString());
          lbl_suffix_idd_i.setFont(new Font("Dialog", Font.PLAIN, 12));
          break;
      case 3:
          lbl_suffix_idd_i = new JLabel("            " + obj_i.get("desc").toString());
          lbl_suffix_idd_i.setFont(new Font("Dialog", Font.PLAIN, 12));
          break;
      default:
          lbl_suffix_idd_i = new JLabel(obj_i.get("desc").toString());
          lbl_suffix_idd_i.setFont(new Font("Dialog", Font.PLAIN, 12));
          break;
      }
 
      GridBagConstraints gbc_lbl_suffix_idd_i = new GridBagConstraints();
      gbc_lbl_suffix_idd_i.insets = new Insets(0, 0, 5, 5);
      gbc_lbl_suffix_idd_i.anchor = GridBagConstraints.WEST;
      gbc_lbl_suffix_idd_i.gridx = 0;
      gbc_lbl_suffix_idd_i.gridy = i;
      panel.add(lbl_suffix_idd_i, gbc_lbl_suffix_idd_i);
    }
 
    for (int k = 0; k <= period; k++) {     
      int a = k + 1;
      final JTextField textField_suffix_idd_k = new JTextField();
 
      switch (weight) {
      case 0:
            textField_suffix_idd_k.setFont(new Font("Dialog", Font.BOLD, 12));
            break;
      case 1:
            textField_suffix_idd_k.setFont(new Font("Dialog", Font.PLAIN, 12));
            break;
      default:
            textField_suffix_idd_k.setFont(new Font("Dialog", Font.PLAIN, 12));
            break;
      }
 
      textField_suffix_idd_k.setBackground(Color.WHITE);
      textField_suffix_idd_k.setColumns(5);
      GridBagConstraints gbc_textField_suffix_idd_k= new GridBagConstraints();
      gbc_textField_suffix_idd_k.fill = GridBagConstraints.HORIZONTAL;
      gbc_textField_suffix_idd_k.insets = new Insets(0, 0, 5, 5);
      gbc_textField_suffix_idd_k.gridx = a;
      gbc_textField_suffix_idd_k.gridy = i;
      panel.add(textField_suffix_idd_k, gbc_textField_suffix_idd_k);
  }

The array is a json tab.
It's generating label and textfield:

Plain text row 1 textfield11 textfield12 textfield13
Plain text row 2 textfield21 textfield22 textfield23
Plain text row 3 textfield31 textfield32 textfield33
....
Plain text row N textfieldN1 textfieldN2 textfieldN3

The problem which I would like to solve:
a) I check checkbox on "Plain text row 1" and hide "Plain text row 2", "Plain text row 3", textfield21, textfield22, textfield23, textfield31, textfield32, textfield33
b) sum of textfield21 and textfield31 equals textfield11 (textfield22 and textfield32 equals textfield12, etc..)

I have no idea how programm it. Is anybody who help me?
Thaks a lot.

Break your problem up into smaller pieces, and concentrate on a single piece at a time instead of posting a hundred lines of code. You want to be able to hide and show components? Use CardLayout. You want to be able to set the content of a component based on actions taken in another? Use a Listener of some kind. If you need more help, then put together an SSCCE demonstrating the specific piece you're working on.
