How to change row background color in JTable dynamically after ticking checkbox in one column?

Question

I'm trying to present some data in JTable. I've created Jtable everything is clear apart from changing background color of some particular rows - thouse in which user tick a checkbox on the last colum. It has to work dynamically. Could you give me some tips, code, etc. please?

Read about TbelCellRenderer and implement your own with the described logic — StanislavL, Jul 09 '14 at 08:03

Something like this?

import java.awt.BorderLayout;
import java.util.Vector;
import javax.swing.*;
import java.awt.*;
import javax.swing.event.TableModelListener;
import javax.swing.table.*;

public class JTableTest extends JFrame implements TableModel{

    Vector<Object[]> lines = new Vector<Object[]>();
    private String[] headers = {"String","Boolean"};

    public JTableTest(){
        for (int t = 0; t < 100; t++) lines.addElement(new Object[]{"Row "+t,Boolean.FALSE});
        JPanel p = (JPanel)getContentPane();
        p.setLayout(new BorderLayout());
        JTable table = new JTable();
        table.setDefaultRenderer(String.class, new MyRenderer());
        p.add(new JScrollPane(table));
        table.setModel(this);
        p.setPreferredSize(new Dimension(400,200));
        pack();
        setVisible(true);
    }
    public static void main(String[] args){
        new JTableTest();
    }
    @Override
    public int getRowCount() {
        return lines.size()+1;
    }
    @Override
    public int getColumnCount() {
        return headers.length;
    }
    @Override
    public String getColumnName(int columnIndex) {
        return headers[columnIndex];
    }
    @Override
    public Class<?> getColumnClass(int col) {
        if (col == 1) return Boolean.class;
        return String.class;
    }
    @Override
    public boolean isCellEditable(int row, int col) {
        return col==1;
    }
    @Override
    public Object getValueAt(int row, int col) {
        return lines.elementAt(row)[col];
    }
    @Override
    public void setValueAt(Object aValue, int row, int col) {
        lines.elementAt(row)[col] = aValue;
    }
    @Override
    public void addTableModelListener(TableModelListener l) {
    }
    @Override
    public void removeTableModelListener(TableModelListener l) {
    }
    private class MyRenderer extends DefaultTableCellRenderer{
        @Override
        public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column){
            Component c = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
            if (lines.elementAt(row)[1] == Boolean.TRUE) c.setBackground(Color.orange);
            else c.setBackground(table.getBackground());
            table.repaint();
            return c;
        }
    }
}
