Create different instance of a tablemodel

[Bill]

Hi all,

I need some help!

I got a class MyClassModel who extends AbstractTablemodel. From a JPanel, i got a JTable that i want to take the model of this class. How can i instanciate this class from my JTable

Something like that :

Code:

JTable table = new Jtable(new MyClassModel()), but this not work.

I also want to pass to MyClassModel a different data (an array or something else) to build my table

thank you for your help

Code:

import javax.swing.*;
import javax.swing.table.*;

public class Test {
    public static void main(String[] args) {
        Test test = new Test();
        JTable table = new JTable(test.getModel());
        JOptionPane.showMessageDialog(null,
                new JScrollPane(table), "",
                JOptionPane.PLAIN_MESSAGE);
    }

    private AbstractTableModel getModel() {
        return new AbstractTableModel() {
            // You must specify at least these 3 methods.
            // See comments in AbstractTableModel api.
            public int getRowCount() { return 10; }

            public int getColumnCount() { return 4; }

            public Object getValueAt(int row, int col) {
                return String.valueOf((row+1)) + (col+1);
            }
        };
    }
}

Hi,

This is an example of my class:

Code:

public class MyTableModel extends AbstractTableModel{

            public MyTableModel(){}

            public int getRowCount() { return 10; }

            public int getColumnCount() { return 4; }

            public Object getValueAt(int row, int col) {
                return String.valueOf((row+1)) + (col+1);
            }
}

and in my panel:

Code:

//in this table, i want to call a new instance of MyTableModel
//to get the model
JTable table = new JTable();

I hope this clear

I don't know to do this ! !

thx a lot

The fact is.......when i loop more than once in

Code:

for(int i=0;i<2;i++){
JTable table = new JTable(/*pass my new instance here*/);
}

than the table take only the last loop to create my model in my table

import java.awt.*;

import javax.swing.table.*;

public class Test {
    public static void main(String[] args) {
        Test test = new Test();
        JPanel panel = new JPanel(new GridLayout(1,0,5,5));
        for(int i = 0; i < 3; i++) {
            JTable table = new JTable(test.getModel());
            Dimension d = table.getPreferredSize();
            d.height = 175;
            table.setPreferredScrollableViewportSize(d);
            panel.add(new JScrollPane(table));
        }
        JOptionPane.showMessageDialog(null,
                new JScrollPane(panel), "",
                JOptionPane.PLAIN_MESSAGE);
    }

    private AbstractTableModel getModel() {
        return new AbstractTableModel() {
            // You must specify at least these 3 methods.
            // See comments in AbstractTableModel api.
            public int getRowCount() { return 10; }

            public int getColumnCount() { return 4; }

            public Object getValueAt(int row, int col) {
                return String.valueOf((row+1)) + (col+1);
            }
        };
    }
}

hi,

its not exactly that i want to do. My AbstractTableModel extends my class not a method return an AbstractTableModel, and my panel is in another class

Code:

Public class MyTableModel extends AbstractTablemodel{

}

and my panel

Code:

public class MyPanel extends JPanel{

}

my loop is in this panel class and i want to instantiate the model of MyTableModel from a JTable in MyPanel.

Thanks a lot for your help
