Hi, sorry ima noob... but can someone help me with adding a List on the right side of my chat window? Currently doing an ISU for my Java course.. Thanks. package components; import java.awt.*; import java.awt.event.*; import javax.swing.*; public class ChatWindow extends JPanel implements ActionListener { protected JTextField textField; protected JTextArea textArea; private final static String newline = "\n"; public ChatWindow() { super(new GridBagLayout()); textArea = new JTextArea(25, 60); textArea.setEditable(false); JScrollPane scrollPane = new JScrollPane(textArea, JScrollPane.VERTICAL_SCROLLBAR_ALWAYS, JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS); textField = new JTextField(20); textField.addActionListener(this); GridBagConstraints c = new GridBagConstraints(); c.gridwidth = GridBagConstraints.REMAINDER; c.fill = GridBagConstraints.BOTH; c.weightx = 1.0; c.weighty = 1.0; add(scrollPane, c); c.fill = GridBagConstraints.HORIZONTAL; add(textField, c); } public void actionPerformed(ActionEvent evt) { String text = textField.getText(); textArea.append(text + newline); textField.selectAll(); textArea.setCaretPosition(textArea.getDocument().getLength()); } /** * Create the GUI and show it. */ private static void createAndShowGUI() { JFrame frame = new JFrame("TextDemo"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.add(new TextDemo()); frame.pack(); frame.setVisible(true); } public static void main(String[] args) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { createAndShowGUI(); } }); } } |
