If you want to dynamically update your table data, you can work with a TableModelListener to find out
when the data changes. The interface consists of one method that tells you when the table data changes.
public interface TableModelListener extends EventListener {
public void tableChanged(TableModelEvent e);
}
import java.awt.BorderLayout;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.event.TableModelEvent;
import javax.swing.event.TableModelListener;
public class TableModelListenerDemo {
public static void main(String args[]) {
final Object rowData[][] = { { "1", "one", "I" }, { "2", "two", "II" }, { "3", "three", "III" } };
final String columnNames[] = { "#", "English", "Roman" };
final JTable table = new JTable(rowData, columnNames);
JScrollPane scrollPane = new JScrollPane(table);
table.getModel().addTableModelListener(new TableModelListener() {
public void tableChanged(TableModelEvent e) {
System.out.println(e);
}
});
table.setValueAt("",0,0);
JFrame frame = new JFrame("Resizing Table");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(scrollPane, BorderLayout.CENTER);
frame.setSize(300, 150);
frame.setVisible(true);
}
}
