    <p>I'm new to GUI design and I'm trying to plan this out before I go too far the wrong way, any help would be nice. I'm trying to display a <code>JTable</code> with rows of <code>Employee</code>, which itself has datatypes of <code>String</code> and <code>ArrayList&lt;Cert&gt;</code>. <code>Cert</code> contains a <code>String</code>.</p> <p>I'd like to have the table present the data for editing, but for a few of the columns I'd like to implement a <code>JComboBox</code> for selection of a <code>String</code> from a set of valid strings, as well as color each option differently (different background colors in the <code>JComboBox</code>).</p> <p>Also, the <code>ArrayList&lt;Cert&gt;</code> currently displays in a cell as [xxx, xxx, ...] where XXX is the return from the <code>toString()</code> function for each item in the <code>ArrayList</code>. I think I'd like to display that <code>ArrayList&lt;Cert&gt;</code> as a read-only <code>JComboBox</code>, but I'm not as concerned with this item.</p> <p>I'm questioning how many classes I need to create to make this happen. I already have a custom model for the <code>JTable</code> extending <code>AbstractTableModel</code>. Do I need to write an extension of <code>JComboBox</code> or do I just need to extend the appropriate renderer for a <code>JComboBox</code> as a cell and do the magic there, then assign that custom renderer to the cell renderer for the <code>String</code> cell?</p> <p>Here's what I have so far, lightly abridged:</p> <pre><code>public class EmployeeTableModel extends AbstractTableModel { ... private ArrayList&lt;Employee&gt; myDataObjects = new ArrayList&lt;Employee&gt;(); ... @Override public Object getValueAt(int row, int column) { Employee emp = myDataObjects.get(row); switch (column) { case 0: return emp.getName(); case 1: return emp.getShift(); case 2: return emp.getCertifications(); default: return ""; } } } </code></pre> <p>Employees:</p> <pre><code>public class Employee { private String name; private String shift; private ArrayList&lt;Cert&gt; certs; ... public String getName() { return name; } public String getShift() { return shift; } public ArrayList&lt;Cert&gt; getCerts() { return certs; } ... } </code></pre> <p>And the initializations:</p> <pre><code>EmployeeTableModel etm = new EmployeeTableModel(); JTable employeeTable = new JTable(); employeeTable.setModel( etm ); </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.
