who make the JScrollPane work ???

Hi,

In my example I put a JTable on a JFrame. I also put a JScrollPane to the JTable.
I give the JTable a 100 rows with some values. For some reason I can 't scroll.
Is it possible to make it work in this example because I really want to keep the line "contentPane.setLayout(null);" and not use another layout.

Thanks for reading and maybe solving my problem

Code:

---


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

public class Interface extends JFrame {


    public Interface() {
           
        Container contentPane = getContentPane();
       
        contentPane.setLayout(null);
       
        JTable t1 = new JTable(100, 5);

        JScrollPane s1 = new JScrollPane(t1);

        contentPane.add(t1);
       
        contentPane.add(s1);

        // Object.setBounds(left, top, with, height);
       
        t1.setBounds(1, 100, 500, 500);
       
        s1.setBounds(501, 100, 20, 500);
       
        for(int i = 0; i < 100; i++) {
               
                t1.setValueAt("Value" + i,i,0);
               
        }
       
       
       
        Dimension d = Toolkit.getDefaultToolkit().getScreenSize();
               
                int w = d.width;
               
                int h = d.height;
               
        this.setSize((int) (((double) w) * 0.9),(int) (((double) h) * 0.9));
       
        this.setLocation((int) (((double) w) * 0.05),(int) (((double) h) * 0.05));
       
        this.setBackground(Color.lightGray );
       
        this.setResizable(false);

            this.setVisible(true);


      this.addWindowListener(new WindowAdapter() {
        public void windowClosing(WindowEvent e) {
        System.exit(0);
        }
        });
    }

    public static void main(String args[]) {
        Interface window = new Interface();
 
    }
}

You only need to add the Scrollpane to your container and not the table as its contained in the ScrollPane.

So just remove these lines

Code:

---

contentPane.add(t1);       
t1.setBounds(1, 100, 500, 500);

---

and you'll probably want to set the size of the scrollPane to the size of the table.

e.g.

Code:

---

s1.setBounds(1, 100, 500, 500);

---

That should then work fine.

Sorry, that doesn 't work.
When I do that, I don 't have a scrollbar at all.
Thanks for trying.

OK this is your code with my modifications. It works fine when i compile and run it.

Code:

---

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

public class Interface extends JFrame {


    public Interface() {
           
        Container contentPane = getContentPane();
       
        contentPane.setLayout(null);
       
        JTable t1 = new JTable(100, 5);

        JScrollPane s1 = new JScrollPane(t1);
       
        contentPane.add(s1);

        // Object.setBounds(left, top, with, height);
       
        s1.setBounds(1, 100, 500, 500);
       
        for(int i = 0; i < 100; i++) {
               
                t1.setValueAt("Value" + i,i,0);
               
        }
       
       
       
        Dimension d = Toolkit.getDefaultToolkit().getScreenSize();
               
                int w = d.width;
               
                int h = d.height;
               
        this.setSize((int) (((double) w) * 0.9),(int) (((double) h) * 0.9));
       
        this.setLocation((int) (((double) w) * 0.05),(int) (((double) h) * 0.05));
       
        this.setBackground(Color.lightGray );
       
        this.setResizable(false);

            this.setVisible(true);


      this.addWindowListener(new WindowAdapter() {
        public void windowClosing(WindowEvent e) {
        System.exit(0);
        }
        });
    }

    public static void main(String args[]) {
        Interface window = new Interface();
 
    }
}

I concur. works fine, heres my code, which works, just for reference:

Code:

---

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

public class Interface extends JFrame {


    public Interface() {

        Container contentPane = getContentPane();

        JTable t1 = new JTable(100, 5);

        JScrollPane s1 = new JScrollPane(t1);

        contentPane.add(s1);

        // Object.setBounds(left, top, with, height);

        t1.setBounds(1, 100, 500, 500);

        s1.setBounds(501, 100, 20, 500);

        for(int i = 0; i < 100; i++) {

                t1.setValueAt("Value" + i,i,0);

        }



        Dimension d = Toolkit.getDefaultToolkit().getScreenSize();

                int w = d.width;

                int h = d.height;

        this.setSize((int) (((double) w) * 0.9),(int) (((double) h) * 0.9));

        this.setLocation((int) (((double) w) * 0.05),(int) (((double) h) * 0.05));

        this.setBackground(Color.lightGray );

        //this.setResizable(false);

            this.setVisible(true);


      this.addWindowListener(new WindowAdapter() {
        public void windowClosing(WindowEvent e) {
        System.exit(0);
        }
        });
    }

    public static void main(String args[]) {
        Interface window = new Interface();

    }
}
