Create copy method in TableModel

Question

Hi everyone!
I have a problem with my table. I have a table and tre buttons(INSERT,DELETE,COPY).
Public class MyDataTable extends JFrame{
JButton insertbtn = new JButton("INSERT");
ActionListener lst = new ActionListener() {
public void actionPerformed(ActionEvent e) {
int row = myTable.getSelectedRow();
data.insert(row);
myTable.tableChanged(new TableModelEvent(data, row, row, TableModelEvent.ALL_COLUMNS, TableModelEvent.INSERT));
myTable.repaint();
insertbtn.addActionListener(lst);
QCButton deletebtn = new QCButton("DELETE");
lst = new ActionListener() {
public void actionPerformed(ActionEvent e) {
int row = myTable.getSelectedRow();
if (data.delete(row))
myTable.tableChanged(new TableModelEvent(data, row, row, TableModelEvent.ALL_COLUMNS, TableModelEvent.INSERT));
myTable.repaint();
deletebtn.addActionListener(lst);
And in my Table model I have :
class MyTableModel extends AbstractTableModel
public boolean delete(int row) {
if (row < 0 || row >= myVector.size())
return false;
myVector.remove(row);
return true;
public void insert(int row) {
if (row < 0)
row = 0;
if (row > myVector.size())
row = myVector.size();
myVector.insertElementAt(new MyData(), row);
Now I want to create a copy method in my Table model, but I dont now how. I want that user be able to copy one row to the end of the table with pressing the COPY button. I am new in Java programming.
Can anybody please help me with that ??????
Thanks

Answer 1

you have a copy button with an actionListener attached to it.
listener for events, process, result.
example.
using radio buttons, check the boolean setSelected() method of the radio button.
u should make the radio buttons part of a buttongroup where only 1 can be selected at a time.
http://java.sun.com/docs/books/tutorial/uiswing/components/button.html#radiobutton
next, iterate thru the tablemodel getting the value of the radio buttons.
use the setSelected() method. when found true get the data vector for that row.
or getValue(row,column) for all columns in that row.
use the data to create an new instance of MyData then use your insert() method at last row or
wherever is desired.
just an idea. good luck.
