    copied!<p>This class is the layout and implementation for the first tab in my program, the CreatePanel. I am trying to implement a JScrollPane in my JTextArea. However, the scroll bar never appears, although the program compiles correctly. I've looked all over for solutions and have tried a couple of variations, but nothing is seeming to work.</p> <pre><code>import java.awt.*; import java.awt.event.*; import javax.swing.*; import java.util.*; public class CreatePanel extends JPanel { private Vector flightList; private SelectPanel sPanel; private JButton createButton; private JLabel airName, flightNumber, departCity, departDay, departTime, arriveCity, arriveDay, arriveTime, price; private JLabel notify, blank; private JTextField l1, l2, l3, l4, l5, l6, l7, l8, l9; private JTextArea flightInfo; private JScrollPane scroll; String air, num, dC, dD, dT, aC, aD, aT, prc; //Constructor initializes components and organize them using certain layouts public CreatePanel(Vector flightList, SelectPanel sPanel) { this.flightList = flightList; this.sPanel = sPanel; // organize components here // creates all labels and textfields for Flight Creation tab notify = new JLabel(""); blank = new JLabel(""); airName = new JLabel("Enter a name of Airlines"); flightNumber = new JLabel("Enter a flight number"); departCity = new JLabel("Enter a departure city"); departDay = new JLabel("Enter a departure day"); departTime = new JLabel("Enter a departure time"); arriveCity = new JLabel("Enter an arrival city"); arriveDay = new JLabel("Enter an arrival day"); arriveTime = new JLabel("Enter an arrival time"); price = new JLabel("Price"); l1 = new JTextField(""); l2 = new JTextField(""); l3 = new JTextField(""); l4 = new JTextField(""); l5 = new JTextField(""); l6 = new JTextField(""); l7 = new JTextField(""); l8 = new JTextField(""); l9 = new JTextField(""); createButton = new JButton("Create a flight"); createButton.addActionListener(new ButtonListener()); flightInfo = new JTextArea("No flight"); flightInfo.setEditable(false); // the user-entered information panel JPanel panelUser = new JPanel(); panelUser.setLayout(new GridLayout(10, 2)); panelUser.add(notify); panelUser.add(blank); panelUser.add(airName); panelUser.add(l1); panelUser.add(flightNumber); panelUser.add(l2); panelUser.add(departCity); panelUser.add(l3); panelUser.add(departDay); panelUser.add(l4); panelUser.add(departTime); panelUser.add(l5); panelUser.add(arriveCity); panelUser.add(l6); panelUser.add(arriveDay); panelUser.add(l7); panelUser.add(arriveTime); panelUser.add(l8); panelUser.add(price); panelUser.add(l9); // panel for the button JPanel panelButton = new JPanel(); panelButton.add(createButton); // the leftside panel of CreatePanel JPanel panelLeft = new JPanel(); panelLeft.setLayout(new BorderLayout()); panelLeft.add(panelUser, BorderLayout.CENTER); panelLeft.add(panelButton, BorderLayout.SOUTH); // the rightside panel of CreatePanel JPanel panelInfo = new JPanel(); scroll = new JScrollPane(flightInfo); scroll.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED); scroll.setVisible(true); panelInfo.setLayout(new GridLayout(1, 1)); panelInfo.add(flightInfo); // WHY WONT YOU WORK? // layout for CreatePanel setLayout(new GridLayout(1, 2)); add(panelLeft); add(panelInfo); } } </code></pre> <p>What am I doing wrong when adding the JScrollPane??</p>
