    <p>In order to add contents to display on a <a href="http://java.sun.com/javase/6/docs/api/javax/swing/JTable.html" rel="noreferrer"><code>JTable</code></a>, one uses the <a href="http://java.sun.com/javase/6/docs/api/javax/swing/table/TableModel.html" rel="noreferrer"><code>TableModel</code></a> to add items to display.</p> <p>One of a way to add a row of data to the <code>DefaultTableModel</code> is by using the <a href="http://java.sun.com/javase/6/docs/api/javax/swing/table/DefaultTableModel.html#addRow(java.lang.Object[])" rel="noreferrer"><code>addRow</code></a> method which will take an array of <code>Object</code>s that represents the objects in the row. Since there are no methods to directly add contents from an <code>ArrayList</code>, one can create an array of <code>Object</code>s by accessing the contents of the <code>ArrayList</code>.</p> <p>The following example uses a <code>KeyValuePair</code> class which is a holder for data (similar to your <code>Track</code> class), which will be used to populate a <a href="http://java.sun.com/javase/6/docs/api/javax/swing/table/DefaultTableModel.html" rel="noreferrer"><code>DefaultTableModel</code></a> to display a table as a <code>JTable</code>:</p> <pre><code>class KeyValuePair { public String key; public String value; public KeyValuePair(String k, String v) { key = k; value = v; } } // ArrayList containing the data to display in the table. ArrayList&lt;KeyValuePair&gt; list = new ArrayList&lt;KeyValuePair&gt;(); list.add(new KeyValuePair("Foo1", "Bar1")); list.add(new KeyValuePair("Foo2", "Bar2")); list.add(new KeyValuePair("Foo3", "Bar3")); // Instantiate JTable and DefaultTableModel, and set it as the // TableModel for the JTable. JTable table = new JTable(); DefaultTableModel model = new DefaultTableModel(); table.setModel(model); model.setColumnIdentifiers(new String[] {"Key", "Value"}); // Populate the JTable (TableModel) with data from ArrayList for (KeyValuePair p : list) { model.addRow(new String[] {p.key, p.value}); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
