need help to set horizontal bar to JList

Hi

I am using JList and I want horizontal scroll bar so I used following code . It shows horizontal bar but not exactly scrollbar. I cann't scroll horizontal.

I used setPrototypeCellValue to fix width of JList . I am unable to see remaining part of the list. That is why I want horizontal scroll bar.

Thanks

Can you please post an SSCCE?

Please help me

Not without an SSCCE.

Do you want me to post whole code?

import javax.swing.DefaultListModel;
import javax.swing.JFrame;
import javax.swing.JList;
import javax.swing.JScrollPane;
import javax.swing.ScrollPaneConstants;

public class ListDisplay extends JFrame{
    JList  lstCrime; 
    private DefaultListModel listModel;

public ListDisplay(){
        GUIDisplay();
    }

public void GUIDisplay(){
        String [] strCrime={"My name is Vaishali","My name is Rajiv","My name is Khushi","My name is Vaishali","My name is Rajiv","My name is Khushi"};

listModel=new DefaultListModel();
        for( int i =0; i< strCrime.length;i++)
           listModel.addElement(strCrime[i]);
        JList  lstCrime;
        lstCrime = new JList(listModel);
        JScrollPane scrlstCrime= new JScrollPane(lstCrime)  ;
        scrlstCrime.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_ALWAYS);
        lstCrime.setPrototypeCellValue("00000000000");
        getContentPane().add(scrlstCrime);
        
        setSize(100, 200);
        setVisible(true);
    }

public static void main(String[] arg){
        ListDisplay main = new ListDisplay();
        main.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }

}

From that method's Javadoc info:

Sets the prototypeCellValue property, and then (if the new value is non-null), computes the fixedCellWidth and fixedCellHeight properties by requesting the cell renderer component for the given value (and index 0) from the cell renderer, and using that component's preferred size.

As I understand it, you've given each cell a fixed width that's shorter than the cells should be. By commenting out that line, as Rob C suggested, each cell gets its correct preferred width.
