<a href="http://doc.qt.nokia.com/stable/qscrollarea.html" rel="nofollow">QScrollArea</a>, for some reason, is ignoring the <code>contentMargins</code> setting when I set <a href="http://doc.qt.nokia.com/stable/qgraphicsview.html" rel="nofollow">QGraphicsView</a> as its widget. Looking at the snippet below, can someone please tell if I'm doing something wrong or it could be a bug in the SDK? Snippet 1 (works perfect): <pre><code>QWidget *appWindow = new QWidget; QScrollArea *sa = new QScrollArea(appWindow); sa->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOn); sa->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOn); sa->setContentMargins(50, 50, 50, 50); QWidget *widgetToScroll = new QWidget(sa); widgetToScroll->resize(5000, 5000); sa->setWidget(widgetToScroll); QVBoxLayout *appWindowLayout = new QVBoxLayout(appWindow); appWindowLayout->addWidget(sa); appWindow->setLayout(appWindowLayout); appWindow->show(); </code></pre> Snippet 2 (It's like <a href="http://doc.qt.nokia.com/stable/qwidget.html#setContentsMargins" rel="nofollow">setContentMargins()</a> call is ignored completely): <pre><code>QWidget *appWindow = new QWidget; QScrollArea *sa = new QScrollArea(appWindow); sa->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOn); sa->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOn); sa->setContentMargins(50, 50, 50, 50); QGraphicsView *widgetToScroll = new QGraphicsView(new QGraphicsScene(sa), sa); widgetToScroll->setAlignment(Qt::AlignLeft | Qt::AlignTop); widgetToScroll->resize(5000, 5000); sa->setWidget(widgetToScroll); QVBoxLayout *appWindowLayout = new QVBoxLayout(appWindow); appWindowLayout->addWidget(sa); appWindow->setLayout(appWindowLayout); appWindow->show(); </code></pre> Thanks.

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.
