Help with Scrollable JList

[Jason]

Hi All,

I know this is probably a non-standard implementation, but for some reason
I cannot get my scrollpane to take effect. I just get a JList with no scrolling
capability. Thanks for your help!

public class IwovSQLForm extends JFrame implements ActionListener//implements
ListSelectionListener
{
private IwovSQLClass sqlClass;
private JList sqlList;
private JScrollPane pane;


/** Use this constructor when calling as Callout */
public IwovSQLForm(IwovSQLClass sqlClass){
this.sqlClass = sqlClass;
this.setTitle("TeamSite SQL Form");
this.setResizable(false);
//this.setDefaultCloseOperation(javax.swing.JFrame.DO_NOTHING_ON_CLOSE);
this.getContentPane().setLayout(new BorderLayout(0,0));
this.setSize(497,321);
this.init();
this.show();
}

/** Set the Frame Title
*/
public IwovSQLForm(String sTitle)
{
this();
setTitle(sTitle);
}

// default constructor
public IwovSQLForm(){}

private void init(){

JPanel p = new JPanel();


JLabel grayBar = new JLabel();
JLabel calloutFieldTitle = new JLabel();
JLabel calloutFieldLabel = new JLabel();
//JLabel iwovIcon = new JLabel("hello", new ImageIcon("http://jsantorolns/iw-icons/newtslogo.gif"),
JLabel.CENTER);
// JLabel iwovIcon = new JLabel("Label", new ImageIcon("newtslogo.gif"),
JLabel.CENTER);


p.setLayout(null);
p.setBackground(java.awt.Color.white);
p.setBounds(0,0,497,321);

calloutFieldTitle.setText("Callout Field:");
calloutFieldTitle.setOpaque(true);
p.add(calloutFieldTitle, BorderLayout.NORTH);
calloutFieldTitle.setForeground(java.awt.Color.black);
calloutFieldTitle.setBackground(java.awt.Color.lightGray);
calloutFieldTitle.setFont(new Font("Dialog", Font.BOLD, 11));
calloutFieldTitle.setBounds(8,25,72,16);

calloutFieldLabel.setText(this.sqlClass.getThisLeafName());
calloutFieldLabel.setOpaque(true);
p.add(calloutFieldLabel);
calloutFieldLabel.setForeground(java.awt.Color.black);
calloutFieldLabel.setBackground(java.awt.Color.lightGray);
calloutFieldLabel.setFont(new Font("Dialog", Font.PLAIN, 11));
calloutFieldLabel.setBounds(84,25,300,16);

try
{
URL tslogo = new URL("http://64.19.155.189/iw-icons/newtslogo.gif");
JLabel iwovIcon = new JLabel("", new ImageIcon(tslogo), JLabel.CENTER);
iwovIcon.setOpaque(true);
p.add(iwovIcon);
iwovIcon.setForeground(java.awt.Color.black);
iwovIcon.setBackground(java.awt.Color.lightGray);
iwovIcon.setBounds(400,4,88,60);
}
catch (MalformedURLException e)
{
//nothing
}

grayBar.setOpaque(true);
p.add(grayBar, BorderLayout.NORTH);
grayBar.setBackground(java.awt.Color.lightGray);
grayBar.setBounds(0,0,497,68);



this.sqlList = new JList(fillDropDownList());
sqlList.setSelectedIndex(0);
sqlList.setBounds(144,75,192,150);
sqlList.setAlignmentX(200);
sqlList.setAlignmentY(70);
sqlList.setOpaque(true);
sqlList.setBackground(java.awt.Color.lightGray);

sqlList.setBorder(BorderFactory.createLoweredBevelBorder());
this.pane = new JScrollPane(sqlList);


JButton JButtonCallBack = new JButton();


p.add(this.sqlList);
p.add(this.pane);
//sqlList.setSelectionMode(MULTIPLE_INTERVAL_SELECTION);



JButtonCallBack.setText("OK");
p.add(JButtonCallBack);
JButtonCallBack.setBounds(176,230,132,41);
JButtonCallBack.addActionListener(this);

this.getContentPane().add(p);
//this.getContentPane().add(BorderLayout.CENTER, p);
}

Here's your problem:

p.add(this.sqlList);
p.add(this.pane);

Remove the first of these two lines. Your "pane" component already contains
"sqlList" and will be responsible for displaying it.
