Hi!

Please, explain me why JTextField: txtFirstName and JTextField: txtLastName are not visible on my JPanel: panfortab?! I can see only JTable: tableDetails.

private void createBaseRight() {
        JPanel panfortab = new JPanel();
        panfortab.setBounds(330, 150, 650, 795);
        panfortab.setVisible(true);
        panfortab.setOpaque(true);
        panfortab.setBorder(bord);
        FilterClass fc = new FilterClass();
        fc.setVisible(true);
        panfortab.add(fc);
        pan.add(panfortab, "Right"); // this is a general panel that includes all components that I've created. Now it has BorderLayout.
}
import java.awt.BorderLayout;
import javax.swing.JPanel;
import javax.swing.JTable;
import javax.swing.RowFilter;
import javax.swing.ScrollPaneConstants;
import javax.swing.table.DefaultTableModel;
import javax.swing.table.TableColumn;
import javax.swing.table.TableRowSorter;

public class FilterClass extends JPanel {
    TableRowSorter rowSorter;
    private DefaultTableModel tableModel;

    public FilterClass() {
        setLayout(new BorderLayout());
        initComponents();
        rowSorter=new TableRowSorter();
        tableModel = (DefaultTableModel) tableDetails.getModel();
        rowSorter.setModel(tableModel);
        tableDetails.setRowSorter(rowSorter);
    }

    private void initComponents() {

        tableDetails = new javax.swing.JTable();
        txtFirstName = new javax.swing.JTextField();
        txtLastName = new javax.swing.JTextField();

        tableDetails.setModel(new javax.swing.table.DefaultTableModel(

        ));

        // Set column widths
        tableDetails.setFillsViewportHeight(true);
        tableDetails.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
        TableColumn col;
        int width = 100;
        col = tableDetails.getColumnModel().getColumn(3);
        col.setPreferredWidth(width);
        col = tableDetails.getColumnModel().getColumn(5);
        col.setPreferredWidth(width);
        jScrollPane1 = new javax.swing.JScrollPane(tableDetails, ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS, ScrollPaneConstants.HORIZONTAL_SCROLLBAR_ALWAYS);
        add(jScrollPane1, "North");

        txtFirstName.addKeyListener(new java.awt.event.KeyAdapter() {
            public void keyReleased(java.awt.event.KeyEvent evt) {
                txFirstNameKeyReleased(evt);
            }
        });

        txtLastName.addKeyListener(new java.awt.event.KeyAdapter() {
            public void keyReleased(java.awt.event.KeyEvent evt) {
                txtLastNameKeyReleased(evt);
            }
        });
    }

    private void txFirstNameKeyReleased(java.awt.event.KeyEvent evt) {
        rowSorter.setRowFilter(RowFilter.regexFilter("(?i)^"+txtFirstName.getText(), 0));
    }

    private void txtLastNameKeyReleased(java.awt.event.KeyEvent evt) {
        rowSorter.setRowFilter(RowFilter.regexFilter("(?i)^" +txtLastName.getText(), 1));
    }

    private javax.swing.JScrollPane jScrollPane1;
    private javax.swing.JTable tableDetails;
    private javax.swing.JTextField txtFirstName;
    private javax.swing.JTextField txtLastName;
}

Yeah, thanks. I've fixed it. Now I'm using GridBaglayout and everything works more or less fine.

I can't see where you add those fields to anything.
