Body
You don't store a <code>QComboBox</code> in a <code>QStandardItemModel</code>. Let's say you have the following choices: A B C D and you have a list with two items in a <code>QListView</code>, the first value being A the second being D: <pre><code> QListView* pView = new QListView(); QStandardItemModel* pModel = new QStandardItemModel(); pView->setModel(pModel); pModel->appendRow(new QStandardItem("A")); pModel->appendRow(new QStandardItem("D")); </code></pre> What we created above is a list widget which will display the values of "A" and "D". Now, to the <code>QComboBox</code>. I assume you want that to edit the values of "A" and "D" in the list. For this, you need to create a <code>QItemDelegate</code>. See <a href="http://doc.qt.io/qt-4.8/qitemdelegate.html" rel="nofollow noreferrer">http://doc.qt.io/qt-4.8/qitemdelegate.html</a> An attempt: <pre><code> class ComboBoxDelegate : public QItemDelegate { Q_OBJECT public: ComboBoxDelegate(QObject *parent = 0); QWidget *createEditor(QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index) const; void setEditorData(QWidget *editor, const QModelIndex &index) const; void setModelData(QWidget *editor, QAbstractItemModel *model, const QModelIndex &index) const; void updateEditorGeometry(QWidget *editor, const QStyleOptionViewItem &option, const QModelIndex &index) const; }; ComboBoxDelegate::ComboBoxDelegate(QObject *parent) : QItemDelegate(parent) { } QWidget *ComboBoxDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &/* option */, const QModelIndex &/* index */) const { QComboBox *editor = new QComboBox(parent); editor->addItem("A"); editor->addItem("B"); editor->addItem("C"); editor->addItem("D"); return editor; } void ComboBoxDelegate::setEditorData(QWidget *editor, const QModelIndex &index) const { QString value = index.model()->data(index, Qt::EditRole).toString(); QComboBox *cBox = static_cast<QComboBox*>(editor); cBox->setCurrentIndex(cBox->findText(value)); } void ComboBoxDelegate::setModelData(QWidget *editor, QAbstractItemModel *model, const QModelIndex &index) const { QComboBox *cBox = static_cast<QComboBox*>(editor); QString value = cBox->currentText(); model->setData(index, value, Qt::EditRole); } void ComboBoxDelegate::updateEditorGeometry(QWidget *editor, const QStyleOptionViewItem &option, const QModelIndex &/* index */) const { editor->setGeometry(option.rect); } </code></pre> And then you need to set the delegate on the <code>QListView</code> to make it work, see: <pre><code>pView->setItemDelegate(new ComboBoxDelegate(pView)); </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.
