When I add a new data row to the table, the scrollbar keeps staying at the same place (not move down). Here's the code:
package nhap; import java.awt.BorderLayout; import java.awt.Container; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.table.DefaultTableModel; public class ModelJTable extends JFrame { private DefaultTableModel model; private JTable table; public ModelJTable() { super(); model = new DefaultTableModel(); model.addColumn("First Name"); model.addColumn("Last Name"); model.addColumn("Years"); String[] socrates = { "Socrates", "", "469-399 B.C." }; model.addRow(socrates); String[] plato = { "Plato", "", "428-347 B.C." }; model.addRow(plato); String[] aquinas = { "Thomas", "Aquinas", "1225-1274" }; model.addRow(aquinas); String[] kierkegaard = { "Soren", "Kierkegaard", "1813-1855" }; model.addRow(kierkegaard); String[] kant = { "Immanuel", "Kant", "1724-1804" }; model.addRow(kant); String[] nietzsche = { "Friedrich", "Nietzsche", "1844-1900" }; model.addRow(nietzsche); String[] arendt = { "Hannah", "Arendt", "1906-1975" }; model.addRow(arendt); table = new JTable(model); JButton addButton = new JButton("Add Philosopher"); addButton.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent event) { String[] philosopher = { "", "", "" }; model.addRow(philosopher); } }); JButton removeButton = new JButton("Remove Selected Philosopher"); removeButton.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent event) { model.removeRow(table.getSelectedRow()); } }); JPanel inputPanel = new JPanel(); inputPanel.add(addButton); inputPanel.add(removeButton); Container container = getContentPane(); container.add(new JScrollPane(table), BorderLayout.CENTER); container.add(inputPanel, BorderLayout.NORTH); setDefaultCloseOperation(EXIT_ON_CLOSE); setSize(400, 200); //pack(); setVisible(true); } public static void main(String args[]) { new ModelJTable(); } }
How can I make the scrollbar go down ? I tried to search Google for answer, but so far I've not found any one. Thanks for your help.

Thanks, Rob Camick. I'm sorry.
Morning came much too soon and it brought along a friend named Margarita Hangover, and a tiny ad.
