    <p>I've made a custom TableCellRenderer that displays a JPanel. When the JPanel contains interactive elements I want those to work too, so I made a custom TableCellEditor. It works, but there is some weird behavior when clicking through the JPanels. Sometimes a JPanel disappears when clicked. When I only set a custom renderer there are no problems at all, except for the JPanels not being interactive. So the problem must be in the TableCellEditor.</p> <p>Editor:</p> <pre><code>public class PanelTableCellEditor extends AbstractCellEditor implements TableCellEditor { private Object _component; @Override public Object getCellEditorValue() { return _component; } @Override public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column) { _component = value; if (value instanceof JPanel) { ((Component) value).setForeground(UIManager.getColor("List.selectionForeground")); ((Component) value).setBackground(UIManager.getColor("List.selectionBackground")); return ((Component) value); } else { return null; } } } </code></pre> <p>Renderer:</p> <pre><code>public class PanelTableCellRenderer extends Component implements TableCellRenderer { @Override public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { if (value instanceof JPanel) { if (isSelected || hasFocus) { ((Component) value).setForeground(UIManager.getColor("List.selectionForeground")); ((Component) value).setBackground(UIManager.getColor("List.selectionBackground")); } else { ((Component) value).setForeground(UIManager.getColor("Panel.foreground")); ((Component) value).setBackground(UIManager.getColor("Panel.background")); } return ((Component) value); } else { return new DefaultTableCellRenderer().getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column); } } } </code></pre> <p>In the main form I have the next code:</p> <pre><code>DefaultTableModel model = new DefaultTableModel(); model.addColumn(null, new Object[] { jPanel1, jPanel2, jPanel1, jPanel2, jPanel1, jPanel2, jPanel1, jPanel2, jPanel1, jPanel2, jPanel1 }); jTable1.setModel(model); TableColumn column = jTable1.getColumnModel().getColumn(0); column.setCellRenderer(new PanelTableCellRenderer()); column.setCellEditor(new PanelTableCellEditor()); jTable1.setRowHeight(50); jTable1.setTableHeader(null); jScrollPane2.setColumnHeaderView(null); </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.
