    <p>I've been pulling my hair out with this one for hours. There's a thread <a href="http://www.qtcentre.org/forum/f-newbie-4/t-how-to-get-the-visible-rect-of-a-qgraphicsview--16541.html" rel="nofollow noreferrer">here</a> about it, but nothing seems to be working. QGraphicsView::rect() will return the width and height, but the <code>left</code> and <code>top</code> values aren't set properly (always 0 -- ignoring the scrolled amount). I want it in scene coordinates, but it should be easy enough to translate from any system. I have no idea what <code>horizontalScrollBar()-&gt;value()</code> and vert are returning...seems to be meaningless jibberish.</p> <hr> <p>@<a href="https://stackoverflow.com/users/121687/fabriziom">fabrizioM</a>:</p> <pre><code>// created here void EditorWindow::createScene() { m_scene = new EditorScene(this); m_view = new EditorView(m_scene); setCentralWidget(m_view); connect(m_scene, SIGNAL(mousePosChanged(QPointF)), this, SLOT(mousePosChanged(QPointF))); } /// with this constructor EditorView::EditorView(QGraphicsScene* scene, QWidget* parent) : QGraphicsView(scene, parent) { setRenderHint(QPainter::Antialiasing); setCacheMode(QGraphicsView::CacheBackground); setViewportUpdateMode(QGraphicsView::FullViewportUpdate); setDragMode(QGraphicsView::NoDrag); scale(1.0, -1.0); // flip coordinate system so that y increases upwards fitInView(-5, -5, 10, 10, Qt::KeepAspectRatio); setInteractive(true); setBackgroundBrush(QBrush(QColor(232,232,232), Qt::DiagCrossPattern)); } </code></pre>

    1. COScratch that...the scrollbar values are relative to... well it can't be the sceneRect() because those are floats... but something similar.

    2. COMaybe is how you construct the QGraphicsView, any source code snippet ?

    3. COI'm not sure what code you want exactly. It doesn't really matter how I construct it... getting the visible rect should be exactly the same.

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.
