Body
Well, after a lot of hair pulling, I got what I needed. My first step was to create a <code>Property</code> class. This class has functions to set or get a name string, a type string, a value double and a unit string. Next, I updated the <code>Node</code> class to include functions to add and remove <code>Property</code> object pointers to a <code>QList<Property *></code>. Also included was a <code>listProperties</code> function that returns all the <code>Property</code> objects from a certain <code>Node</code>. After this, the function to populate the <code>QTableWidget</code> with a certain <code>Node</code>'s properties was coded like this: <pre><code> propertiesList = node->listMyProperties(); for (int row = 0; row < propertiesList.size(); ++row) { Property *property = propertiesList.at(row); addRow(); tableWidget->item(row, 0)->setData(Qt::DisplayRole, property->propertyName()); tableWidget->item(row, 1)->setData(Qt::DisplayRole, property->propertyType()); tableWidget->item(row, 2)->setData(Qt::DisplayRole, property->propertyValue()); tableWidget->item(row, 3)->setData(Qt::DisplayRole, property->propertyUnit()); } </code></pre> And the <code>addRow()</code> function: <pre><code>void PropertiesDialog::addRow() { int row = tableWidget->rowCount(); tableWidget->insertRow(row); QTableWidgetItem *item0 = new QTableWidgetItem; item0->setTextAlignment(Qt::AlignRight | Qt::AlignVCenter); tableWidget->setItem(row, 0, item0); QTableWidgetItem *item1 = new QTableWidgetItem; item1->setTextAlignment(Qt::AlignRight | Qt::AlignVCenter); tableWidget->setItem(row, 1, item1); QTableWidgetItem *item2 = new QTableWidgetItem; item2->setTextAlignment(Qt::AlignRight | Qt::AlignVCenter); tableWidget->setItem(row, 2, item2); QTableWidgetItem *item3 = new QTableWidgetItem; item3->setTextAlignment(Qt::AlignRight | Qt::AlignVCenter); tableWidget->setItem(row, 3, item3); tableWidget->setCurrentItem(item0); } </code></pre> This produces what I needed: to have a class to hold the property values related to each node, and present them on a <code>QTableWidget</code>. Next step is to make the reverse path, meaning, when edits occur in the <code>QTableWidget</code>, those changes should propagate to the class. Now I think I can find my way, hope this helps anyone trying to find something related. I'll also update the tags and maybe edit the title to make it more relevant/meaningful.

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.
