copied!<p>You are using the <code>DefaultListModel</code> which uses a <code>DefaultListCellRenderer</code>. I don't see any part in your code that actually makes use of your <code>HumanRenderer</code>. You have to write your own Model.</p> <pre><code>public class HumanListModel extends DefaultListModel { private ArrayList<Human> data; public HumanListModel() { super(); data = new ArrayList<Human>(); } public void addHuman(Human h) { // add new human to the model data.add(h); fireTableStructureChanged(); } public void removeHuman(Human h) { data.remove(h); fireTableStructureChanged(); } @Override public int getColumnCount() { // the number of columns you want to display return 1; } @Override public int getRowCount() { return data.size(); } @Override public Object getValueAt(int row, int col) { return (row < data.size()) ? data.get(row) : null; } @Override public String getColumnName(int col) { return "Human"; } @Override public Class getColumnClass(int col) { return Human.class; } } </code></pre> <p>For your <code>JTable</code> you just have to set the <code>HumanListModel</code> and define your renderer. All changes to your data should afterwards directely made at the model. Ergo use: <code>model.addHuman()</code> and <code>model.removeHuman()</code>. They fire the necessary Events which the <code>JTable</code> listens for in order to repaint.</p> <pre><code>HumanListModel model = new HumanListModel(); JTable newbies = new JTable(model); newbies.setDefaultRenderer(Human.class, new HumanRenderer()); </code></pre> <p>I hope it works...</p>
