Body
Here is a solution. For this to work properly, your column should not have the <code>Qt::ItemIsEditable</code> or <code>Qt::ItemIsUserCheckable</code> flags set. This reads the boolean values from <code>Qt::DisplayRole</code> and calls <code>setData()</code> with <code>Qt::EditRole</code> (i.e. not <code>Qt::CheckStateRole</code>.) <pre><code>#include "check_box_delegate.h" #include <QtGui/QApplication> #include <QtGui/QMouseEvent> static QRect CheckBoxRect(const QStyleOptionViewItem &view_item_style_options) { QStyleOptionButton check_box_style_option; QRect check_box_rect = QApplication::style()->subElementRect( QStyle::SE_CheckBoxIndicator, &check_box_style_option); QPoint check_box_point(view_item_style_options.rect.x() + view_item_style_options.rect.width() / 2 - check_box_rect.width() / 2, view_item_style_options.rect.y() + view_item_style_options.rect.height() / 2 - check_box_rect.height() / 2); return QRect(check_box_point, check_box_rect.size()); } CheckBoxDelegate::CheckBoxDelegate(QObject *parent) : QStyledItemDelegate(parent) { } void CheckBoxDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const { bool checked = index.model()->data(index, Qt::DisplayRole).toBool(); QStyleOptionButton check_box_style_option; check_box_style_option.state |= QStyle::State_Enabled; if (checked) { check_box_style_option.state |= QStyle::State_On; } else { check_box_style_option.state |= QStyle::State_Off; } check_box_style_option.rect = CheckBoxRect(option); QApplication::style()->drawControl(QStyle::CE_CheckBox, &check_box_style_option, painter); } // This is essentially copied from QStyledItemEditor, except that we // have to determine our own "hot zone" for the mouse click. bool CheckBoxDelegate::editorEvent(QEvent *event, QAbstractItemModel *model, const QStyleOptionViewItem &option, const QModelIndex &index) { if ((event->type() == QEvent::MouseButtonRelease) || (event->type() == QEvent::MouseButtonDblClick)) { QMouseEvent *mouse_event = static_cast<QMouseEvent*>(event); if (mouse_event->button() != Qt::LeftButton || !CheckBoxRect(option).contains(mouse_event->pos())) { return false; } if (event->type() == QEvent::MouseButtonDblClick) { return true; } } else if (event->type() == QEvent::KeyPress) { if (static_cast<QKeyEvent*>(event)->key() != Qt::Key_Space && static_cast<QKeyEvent*>(event)->key() != Qt::Key_Select) { return false; } } else { return false; } bool checked = index.model()->data(index, Qt::DisplayRole).toBool(); return model->setData(index, !checked, Qt::EditRole); } </code></pre>

Guidance

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.
