JTable - Preventing user input.

I am using a JTable. I want to have the rows selectable, however I dont want the user to be able to edit or input data directly via the table.

I can use: jTable1.setCellSelectionEnabled(false);

However this stops the rows being highligted when clicked on how do I go about this??

Thanks for Reading


Scottie!!

A way to achieve that, it’s creating a TableModel class which extends from a AbstractTableModel. Here is an example:

Code:

---

import javax.swing.table.AbstractTableModel;

public class MyTableModel extends AbstractTableModel{
        String[] columnNames = {"First Name",
                                                        "Last Name",
                                                        "Sport",
                                                        "# of Years"};
       
        Object[][] data = {
                        {"Mary", "Campione",
                                "Snowboarding", new Integer(5)},
                                {"Alison", "Huml",
                                        "Rowing", new Integer(3)},
                                        {"Kathy", "Walrath",
                                                "Knitting", new Integer(2)}};
       
        public MyTableModel(){
               
        }
    public int getColumnCount() {
        return columnNames.length;
    }

    public int getRowCount() {
        return data.length;
    }

    public String getColumnName(int col) {
        return columnNames[col];
    }

    public Object getValueAt(int row, int col) {
        return data[row][col];
    }
        public boolean isCellEditable(int row, int col) {
                return false;
        }
}

If you want, you can test it, using the following code:

Code:

---

import java.awt.*;
import javax.swing.*;

public class JTableSample extends JFrame{
       
        public JTableSample() {
                JTable table = new JTable(new MyTableModel());
                table.setPreferredScrollableViewportSize(new Dimension(500, 70));
               
                //Create the scroll pane and add the table to it.
                JScrollPane scrollPane = new JScrollPane(table);
               
                //Add the scroll pane to this panel.
                this.getContentPane().add(scrollPane);
               
                this.setDefaultCloseOperation(EXIT_ON_CLOSE);
                this.setSize(500,300);
        }
       
        public static void main(String[] args) {
                JTableSample t = new JTableSample();
                t.setVisible(true);
        }
       
}

Thanks a lovely example.

Works fine now.

Now all I need to do is prevent the colums from being moved via drag n drop.

Add the following line to your code:

table.getTableHeader().setReorderingAllowed(false);

Code:

---

import java.awt.*;
import javax.swing.*;

public class JTableSample extends JFrame{
       
        public JTableSample() {
                JTable table = new JTable(new MyTableModel());
                table.setPreferredScrollableViewportSize(new Dimension(500, 70));
                table.getTableHeader().setReorderingAllowed(false);
               
                //Create the scroll pane and add the table to it.
                JScrollPane scrollPane = new JScrollPane(table);
               
                //Add the scroll pane to this panel.
                this.getContentPane().add(scrollPane);
               
                this.setDefaultCloseOperation(EXIT_ON_CLOSE);
                this.setSize(500,300);
        }
       
        public static void main(String[] args) {
                JTableSample t = new JTableSample();
                t.setVisible(true);
        }
       
}
