Hi All,

I have a JScrollPane on a JFrame. The JScrollPane contain a JPanel.On
click of a JButton, i'm adding new JButtons to this JPanel, side by
side.

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

public class DynamicScroll extends JFrame implements ActionListener{

    private int buttonCount = 0;
    private JButton jButton1;
    private JPanel jPanelInScrollPane;
    private JScrollPane jScrollPane1;

    public DynamicScroll() {
        jScrollPane1 = new JScrollPane();
        jPanelInScrollPane = new JPanel();
        jButton1 = new JButton();

        getContentPane().setLayout(null);
        jPanelInScrollPane.setLayout(null);

        jScrollPane1.setViewportView(jPanelInScrollPane);
        getContentPane().add(jScrollPane1);
        jScrollPane1.setBounds(40, 40, 320, 80);

        jButton1.setText("Add Button");
        jButton1.addActionListener(this);

        getContentPane().add(jButton1);
        jButton1.setBounds(150, 170, 120, 23);

    }

    public void actionPerformed(ActionEvent evt) {
       JButton newButton = new JButton("Button "+ buttonCount);
        newButton.setBounds( buttonCount  * (100)+10, 5,  100, 50);
        jPanelInScrollPane.add(newButton);
        buttonCount ++ ;
        jPanelInScrollPane.repaint();
        jPanelInScrollPane.validate();
    }

    public static void main(String args[]) {
        DynamicScroll ds = new DynamicScroll();
        ds.setSize(400,300);
        ds.setVisible(true);
    }
}


Starting from the 4th button which is added dynamically, the buttons
goes outside the JScrollPane. I want the scrollbars of the JScrollPane
to appear when the dynamically added buttons are outside the area of
the JScrollPane so that i can scroll and view all the added JButtons.
Kindly advice on how this can be done.

Thanks in advance

Chanchal
