Hier ist eine einfache Implementation einer TreeTable (gem. Alexandru Toth), die ein gemeinsames Model für JTree und JTable benutzt. Es ist dann kein Problem mehr, dynamisch neue Zeilen hinzuzufügen:
<code=java>package treetable;

/** JTable that has different renderers depending on the classes in TreeModel */ public class Table extends JTable {
void registerRenderers() { setDefaultRenderer(Color.class, new TableColorRenderer(Color.WHITE)); }
public Table() { super();
registerRenderers(); }
public Table(TableModel dm) { super(dm);
registerRenderers(); }
public Table(TableModel dm, TableColumnModel cm) { super(dm, cm);
registerRenderers(); }
@Override public TableCellRenderer getCellRenderer(int row, int column) { Object value = getModel().getValueAt(row, column);
/** enable to have custom renderers depending on class of cell */ TableCellRenderer tcr = getDefaultRenderer(value.getClass());
return tcr; }
}</code=java>
