JTable - Preventing user input.

[scottie_uk]

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

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

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:

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);

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);
	}
	
}
