    <p>I don't deal with QTableView+QStandardItemModel, but may be example below will help you:</p> <p>1). table.h file:</p> <pre><code>#ifndef TABLE__H #define TABLE__H #include &lt;QtGui&gt; class ItemDelegate : public QItemDelegate { public: ItemDelegate(QObject *parent = 0) : QItemDelegate(parent) { } virtual void drawCheck(QPainter *painter, const QStyleOptionViewItem &amp;option, const QRect &amp;, Qt::CheckState state) const { const int textMargin = QApplication::style()-&gt;pixelMetric(QStyle::PM_FocusFrameHMargin) + 1; QRect checkRect = QStyle::alignedRect(option.direction, Qt::AlignCenter, check(option, option.rect, Qt::Checked).size(), QRect(option.rect.x() + textMargin, option.rect.y(), option.rect.width() - (textMargin * 2), option.rect.height())); QItemDelegate::drawCheck(painter, option, checkRect, state); } virtual bool editorEvent(QEvent *event, QAbstractItemModel *model, const QStyleOptionViewItem &amp;option, const QModelIndex &amp;index) { Q_ASSERT(event); Q_ASSERT(model); // make sure that the item is checkable Qt::ItemFlags flags = model-&gt;flags(index); if (!(flags &amp; Qt::ItemIsUserCheckable) || !(flags &amp; Qt::ItemIsEnabled)) return false; // make sure that we have a check state QVariant value = index.data(Qt::CheckStateRole); if (!value.isValid()) return false; // make sure that we have the right event type if (event-&gt;type() == QEvent::MouseButtonRelease) { const int textMargin = QApplication::style()-&gt;pixelMetric(QStyle::PM_FocusFrameHMargin) + 1; QRect checkRect = QStyle::alignedRect(option.direction, Qt::AlignCenter, check(option, option.rect, Qt::Checked).size(), QRect(option.rect.x() + textMargin, option.rect.y(), option.rect.width() - (2 * textMargin), option.rect.height())); if (!checkRect.contains(static_cast&lt;QMouseEvent*&gt;(event)-&gt;pos())) return false; } else if (event-&gt;type() == QEvent::KeyPress) { if (static_cast&lt;QKeyEvent*&gt;(event)-&gt;key() != Qt::Key_Space &amp;&amp; static_cast&lt;QKeyEvent*&gt;(event)-&gt;key() != Qt::Key_Select) return false; } else { return false; } Qt::CheckState state = (static_cast&lt;Qt::CheckState&gt;(value.toInt()) == Qt::Checked ?

    1. COThanks a lot !!! It does works :D~\n However, by this way, every element in the tableview will contain a check box, if I just want the checkbox appears in some specific columns, which part I need to modify ?? Thank you again,, this example is really helpful :D

    2. CO@Claire Huang You may edit *Table* class to gain ability set checkboxes just in one selected column, example: for (...) for (...) { setItem(...); if (j == mySelectedColumn) item->setFlags(Qt::ItemIsEnabled|Qt::ItemIsUserCheckable); else item->setFlags(Qt::ItemIsEnabled); } ... etc I think something like that. :)

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.
