    <p>I came up with a satisfying solution based on implementing a custom <code>ListCellRenderer</code>.</p> <pre><code>import java.awt.Component; import javax.swing.DefaultListCellRenderer; import javax.swing.JList; import javax.swing.ListCellRenderer; public class DynamicCellRenderer implements ListCellRenderer { private final ListCellRenderer listCellRenderer; private String displayMember; public DynamicCellRenderer(String displayMember) { this(displayMember, new DefaultListCellRenderer()); } public DynamicCellRenderer(String displayMember, ListCellRenderer wrapped) { listCellRenderer = wrapped; this.displayMember = displayMember; } @Override public Component getListCellRendererComponent(JList list, Object value, int index, boolean isSelected, boolean cellHasFocus) { Object displayMemberValue = getDisplayMemberValue(value); return listCellRenderer.getListCellRendererComponent(list, displayMemberValue, index, isSelected, cellHasFocus); } private Object getDisplayMemberValue(Object value) { // value is the domain class // only works if display member is a method, TODO: fallback to field // displayMember is something like "getName" -&gt; value.getName() gets called try { return value.getClass().getMethod(displayMember).invoke(value); } catch (Exception ex) { // if anything went wrong it is the programmers fault -&gt; propagate exception throw new RuntimeException(ex); } } public String getDisplayMember() { return displayMember; } public void setDisplayMember(String displayMember) { this.displayMember = displayMember; } } </code></pre> <p>In your client GUI code you can do something like this:</p> <pre><code>jListBox1.setCellRenderer(new DynamicCellRenderer("getName")); ... ... // and later at some point ((DynamicCellRenderer) jListBox1.getCellRenderer()).setDisplayMember("getEmail"); </code></pre>

    1. COI'd also suggest storing the method when it changes rather than calling value.getClass().getMethod(displayMember) on every re-rendering. No need to search for the method if it hasn't changed.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
