Study the code below. There is something wrong with it! Can you guess what it is?
public class JTableViewToModelColumn {
public static void main(String[] args) {
JFrame f = new JFrame("View To Model Column Example");
final DefaultTableModel model = new DefaultTableModel();
model.setColumnIdentifiers(new String[]{"Col A", "Col B", "Col C"} );
model.setRowCount(10);
final JTable table = new JTable(model);
table.addMouseListener(new MouseAdapter() {
@Override
public void mouseClicked(MouseEvent e) {
int col = table.columnAtPoint(e.getPoint());
System.out.println("You click on column " + model.getColumnName(col));
}
});
f.add(new JScrollPane(table), BorderLayout.CENTER);
f.pack();
f.setVisible(true);
}
}
