Thread: Add JScrollPane to a JPanel

Hello,

I have this interface to create. I have a problem with the JScrollPane:

I posted in Add JScrollPane to a JPanel - Stack Overflow but I didn't get answer.



I declared a JPanel with a Gridlayout(8,1,0,2), I want 8 rows appear in this panel. A row is a JPanel to, I set the size to make the 8 row panels appear in the big panel. If the number of rows pass 8, I get two columns ... I added a JScrollPane but it doesn't appear. Testing button at the place of button, the scrollpane appear but returning to panel it disappear..

How can I do ??

I have a frame.
I applyed AbsoluteLayout in this frame Then I added a panel with a GridLayout.
Clicking with mouse left button and Surround with, I chose JscrollPane .

Yhis is the code without Sourround with JScrollPane

package d06.m03;
 
import java.awt.BorderLayout;
import java.awt.EventQueue;
 
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;
import javax.swing.JButton;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import javax.swing.JScrollPane;
import java.awt.GridLayout;
import java.awt.SystemColor;
 
public class ActionExample4 extends JFrame {
 	/**
	 * Launch the application.
	 */
	public static void main(String[] args) {
		EventQueue.invokeLater(new Runnable() {
			public void run() {
				try {
					ActionExample4 frame = new ActionExample4();
					frame.setVisible(true);
				} catch (Exception e) {
					e.printStackTrace();
				}
			}
		});
	}
 
	/**
	 * Create the frame.
	 */
	public ActionExample4() {
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setBounds(100, 100, 594, 426);
		getContentPane().setLayout(null);
 
		JPanel panel = new JPanel();
		panel.setBackground(SystemColor.activeCaption);
		panel.setBounds(91, 11, 154, 264);
		getContentPane().add(panel);
		panel.setLayout(new GridLayout(8, 1, 1, 2));
 
 
		  for(int i=0;i<9;i++)
		{
			JPanel panel_1 = new JPanel();
		   panel.add(panel_1);
		} 
 
 
 
	}
}

and with surround :

 
package d06.m03;
 
import java.awt.BorderLayout;
import java.awt.EventQueue;
 
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;
import javax.swing.JButton;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import javax.swing.JScrollPane;
import java.awt.GridLayout;
import java.awt.SystemColor;
 
public class ActionExample4 extends JFrame {
 	/**
	 * Launch the application.
	 */
	public static void main(String[] args) {
		EventQueue.invokeLater(new Runnable() {
			public void run() {
				try {
					ActionExample4 frame = new ActionExample4();
					frame.setVisible(true);
				} catch (Exception e) {
					e.printStackTrace();
				}
			}
		});
	}
 
	/**
	 * Create the frame.
	 */
	public ActionExample4() {
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setBounds(100, 100, 594, 426);
		getContentPane().setLayout(null);
 
		JScrollPane scrollPane = new JScrollPane();
		scrollPane.setBounds(91, 11, 154, 264);
		getContentPane().add(scrollPane);
 
		JPanel panel = new JPanel();
		scrollPane.setViewportView(panel);
		panel.setBackground(SystemColor.activeCaption);
		panel.setLayout(new GridLayout(8, 1, 1, 2));
 
 
		  for(int i=0;i<9;i++)
		{
			JPanel panel_1 = new JPanel();
		   panel.add(panel_1);
		} 
 
 
 
	}
}

this is the output with both codes:


I want it like this:



Thanks in advance.
