TableModelListener介于两个不同的JTable之间

Question

I am currently working with two JTable. Each of them has its own custom TableModel.

In the first JTable i have items that can be select (checkbox). The second one starts empty. When i check a line in the first table, the backgroundColor of the line changes (thanks to a preparedRenderer method) and i would like the content of the checked line to be added in the second JTable.

I suppose i should use a TableModelListener but i don't see how i tell the second Table (and its model) to listen to the first one.

Does anyone have some thought about that ?

Here is a sample of what the code i got look like :

public class MyClass {

    private Model1 model1;
    private Model2 model2;

    private JTable table1;
    private JTable table2;

    public void myMethod()
    {
        table1 = new JTable();
        model1 = new Model1();
        table1.setModel(model1);

        table1.getModel().addTableModelListener(new TableModelListener()
        {
            @Override
            public void tableChanged(TableModelEvent e) 
            {
                //Here some code to enable a button when at least one row is checked
                //that works fine
            }
        });


        table2 = new JTable();
        model2 = new Model2();
        table2.setModel(model2);
    }
}

Thanks for your help :)

• don't to use TableModelListener , override setValueAt ( Each of them has its own custom TableModel. ) for first XxxTableModel eg tableModelFirts.setValueAt(whatever_linked_in_second_model)

• TableModelListener could not be used as notifier to change value in model, inside or outside

You can update model2 in the listener of model1 and refresh its table2:

public class MyClass  {

    private Model1 model1;
    private Model2 model2;

    private JTable table1;
    private JTable table2;

    public void myMethod()
    {
        table1 = new JTable();
        model1 = new Model1();
        table1.setModel(model1);

        table2 = new JTable();
        model2 = new Model2();
        table2.setModel(model2);

        table1.getModel().addTableModelListener(new TableModelListener()
        {
            @Override
            public void tableChanged(TableModelEvent e) 
            {
                //Here some code to enable a button when at least one row is checked
                //that works fine
                Object aValue = "something"; //fill
                int row = 1; //fill
                int column = 1; //fill
                model2.setValueAt(aValue, row, column);
                model2.fireTableDataChanged();
            }
        });
    }
}

Thanks guys !

I finally managed to get it working. I used a mix of your solutions.

In my tableListener (from table1) i get the checked object and call the setValue method from my table2 that i have override to do what i want (because my object is a custom object).
