Array of jpanels within JScrollPane

[Mandar Khire]

I try to create Array of jpanels within JScrollPane...
I partially done same but instead of JScrollPane i created jpanel....you can see code here.
Here i write simple code for JScrollPane

import java.awt.Color;
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.Graphics;
import java.awt.GraphicsEnvironment;
import java.awt.Image;
import java.awt.Point;
import java.awt.Rectangle;
import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.SwingUtilities;
public class scp {
	static int Array_counter = 11;                                         
	static int counter,j,k = 0; 
	static JPanel[] panels = new JPanel[Array_counter];					
	static JLabel[] labels = new JLabel[Array_counter];	
	JFrame myframe = new JFrame();  
	sp bgp = new sp();
	int sys_want_w, sys_want_h;
	Point locations;
	Point locations1;	
	public void mygui() {
		GraphicsEnvironment env = GraphicsEnvironment
		.getLocalGraphicsEnvironment();
		System.out.println(env.getMaximumWindowBounds());
		sys_want_w = env.getMaximumWindowBounds().width;
		sys_want_h = env.getMaximumWindowBounds().height;
		JScrollPane myjScrollPane = new JScrollPane(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS,JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
		myjScrollPane.setViewportBorder(BorderFactory.createLineBorder(Color.black, 1));
		myframe.setSize(800, 600);
		myframe.setLocationRelativeTo(null);
		myframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		myframe.setVisible(true);
		myframe.setResizable(true);
		bgp.setLayout(null);
		bgp.setSize(new Dimension(364, 96));
		bgp.setOpaque(true);
		bgp.setBorder(BorderFactory.createLineBorder(Color.black, 1));
	Rectangle r1 = new Rectangle(myjScrollPane.getX(), myjScrollPane.getY(),myjScrollPane.getWidth(), myjScrollPane.getHeight());
		bgp.setBounds(r1);
		myjScrollPane.add(bgp);
		myjScrollPane.computeVisibleRect(r1);
	    myjScrollPane.setBounds(myframe.getX(),myframe.getY(),myframe.getWidth(),myframe.getHeight());
	    myjScrollPane.setViewportView(bgp);	    
	  myjScrollPane.computeVisibleRect(bgp.getBounds());
		myframe.getContentPane().add(myjScrollPane);
		for (counter = 0; counter < panels.length; counter++) {
			panels[counter] = new JPanel();
			panels[counter].setLayout(new FlowLayout()); 
			panels[counter].setBackground(new Color(255, 255, 204));
			panels[counter].setSize(25, 25);
			panels[counter].setBorder(BorderFactory.createLineBorder(Color.black,1));
			panels[counter].setName(String.valueOf(counter)); 
			labels[counter] = new JLabel();
			labels[counter].setText(String.valueOf(counter));
			panels[counter].add(labels[counter], null); 
			panels[counter].setOpaque(true);
			Point locations = new Point((0 + (26 * k)), ((j)));
			k++;
			panels[counter].setLocation(locations);
			bgp.add(panels[counter]);
		}
	}
	public static void main(String[] args) {
		SwingUtilities.invokeLater(new Runnable() {
			public void run() {
				new scp().mygui();
			}
		});
	}
	class sp extends JPanel {
		private static final long serialVersionUID = 1L;
		Image image;
		public sp() {
			try {
				image = javax.imageio.ImageIO.read(new java.net.URL(getClass().getResource("bg.jpg"), "bg.jpg"));
			} catch (Exception e) { /* handled in paintComponent() */
			}
		}
		@Override
		protected void paintComponent(Graphics gr) {
			super.paintComponent(gr);
			if (image != null)
				gr.drawImage(image, 0, 0, sys_want_w - 8, sys_want_h - 35, this);
		}
	}
}

Now question is i can see both scrollbar but it cant move...
i try to search but not found...
I know its may be silly mistake...

what's in the viewport has to have a preferredSize set greater than the viewport's size.

change this
//bgp.setSize(new Dimension(364, 96));
to
bgp.setPreferredSize(new Dimension(1000,1000));
