[aahme001]

Hey everyone,

I was working on small program for building GUIs,
the progam that I was working on has LIST and TEXTAREA and three buttons below them. Here is my problem:

I was trying to incorprate a scrolbar into the LIST,but somehow I am unable to achieve that because I am new to java, Can anyone tell me how I can achieve my goal ? here is the code developed so far :

code


import java.awt.*;
import java.awt.event.*;
 import javax.swing.JList;
 import javax.swing.JPanel;
 import javax.swing.JLabel;
 import javax.swing.*;


 import javax.swing.JFrame;
 import javax.swing.DefaultListModel;
 import java.awt.event.WindowAdapter;
 import java.awt.event.WindowEvent;
 
 import javax.swing.JMenu;
 import javax.swing.JMenuItem;
 import javax.swing.JMenuBar;

public class NurseSystem extends JFrame
{
      
	public NurseSystem()
	{
	    JMenuBar menuBar = new JMenuBar();
       JMenu fileMenu = new JMenu("File");
       JMenu editMenu = new JMenu("Edit");
       
       //add sub menus
       JMenuItem newFileItem = new JMenuItem("New");
       JMenuItem openFileItem = new JMenuItem("open");
       
       JMenuItem addFileItem = new JMenuItem("Add");
       JMenuItem ModifyFileItem = new JMenuItem("Modify");
       JMenuItem deleteFileItem = new JMenuItem("Delete");
      
       //file submenu
       fileMenu.add(newFileItem);
       fileMenu.add(openFileItem);
       //add edit submenu
       editMenu.add(addFileItem);
       editMenu.add(ModifyFileItem);
       editMenu.add(deleteFileItem);
       
        //Add the menus to the menubar
       menuBar.add (fileMenu);
       menuBar.add (editMenu);
       
       //add the menubar to the application window
       setJMenuBar (menuBar);
       
       //Name and Detailed labels 
      JLabel label1 = new JLabel("                                     ");
      JLabel label2 = new JLabel("                                      ");
 
      JLabel nurseName = new JLabel("Nurse Name",JLabel.LEFT);
      JLabel detailedInfo = new JLabel("Detailed Information");
      
      //Create a LIst

       //set component layout
	    FlowLayout layout = new FlowLayout();
	    Container mainWindow = getContentPane();
	    mainWindow.setLayout (layout);
	    //add labels to the main Window
	    mainWindow.add(nurseName);
	    mainWindow.add(label1);
	    mainWindow.add(label2);
	    mainWindow.add(detailedInfo);
	

	 
	

      
	
		this.addWindowListener	(new WindowAdapter(){
			public void windowClosing(WindowEvent e){
				dispose();
				System.exit(0);
			}
		});
	}
	
	public static void main(String args[])
	{
	   System.out.print("Nurse System");
		NurseSystem f = new NurseSystem();
		f.setSize(500,400);
		f.show();
	} 
}

To add scroll bars to a control:

JTextArea textBox = new JTextArea();
JScrollPane myPane = newJScrollPane(textBox);
