编辑JTable中新添加的行

Question

i added a Row in my JTable with this popupmenu:

    final JPopupMenu popupMenu = new JPopupMenu();
    JMenuItem addItem = new JMenuItem("Add Movie");
    JMenuItem deleteItem = new JMenuItem("Delete Movie");

    addItem.addActionListener(new ActionListener() 
    {
        @Override
        public void actionPerformed(ActionEvent e) {
            System.out.println("test");
            Object frame = null;
            JOptionPane.showMessageDialog((Component) frame, "Movie wurde hinzugefügt!");

            model.addRow(new Movie("", 0, "", "", null, "DE"));
        }
    });
    deleteItem.addActionListener(new ActionListener() 
    {
        @Override
        public void actionPerformed(ActionEvent e) {
            Object frame = null;
            JOptionPane.showMessageDialog((Component) frame, "Movie wurde gelöscht");
        }
    });

    popupMenu.add(addItem);
    popupMenu.add(deleteItem);
    table.setComponentPopupMenu(popupMenu);

But alway, when i try to edit the values in this row i get an Error-Message. Does anybody know why?

Exception in thread "AWT-EventQueue-3" java.lang.IndexOutOfBoundsException: Invalid range

Can you help me?

Answer 1

You probably didn't implement the addRow() method properly.

You need to add the Movie object to your movie List and then invoke fireTableRowsInserted(...).

Check out Row Table Model . The RowTableModel class will give you an idea of how to implement the addRow() method.
