    <p>I agree with Neox, the picture is not really a pie ;). If you want an actual pie (that is: a segment of a circle) you can use the inbuilt method of painter:</p> <pre><code>QRect rect( -radius, -radius, radius*2, radius*2); painter-&gt;drawPie( rect, startAngle*16, span*16 ); </code></pre> <p><code>int radius</code><br> the radius of your pie, obviously. </p> <p><code>int startAngle</code><br> where your pie starts, e.g. 20° offset from the positive X axis </p> <p><code>int span</code><br> number of degrees that the arc stretches, e.g. a pie with span = 320° would end at a total of 340°, or -20° from the positive X axis. (see QPainter Documentation for the miraculous *16)</p> <p>This should give you a nice PacMan ^^ - or you can play around with the values.</p> <p>Now, without any more details you need to figure out where to actually place this snippet. Naturally, it would be in the paint method of a some graphical item, e.g. a custom QGraphicsItem, and hence use the painter that comes as input to this method. This really depends on your setup of widgets and stuff...</p> <p>Qt has actually a pretty awesome documentation, so make sure to check this out first: (I've only been at it for two weeks myself, but you can get pretty far with the documentation)</p> <p>QGraphicsItem: <a href="http://qt-project.org/doc/qt-4.8/qgraphicsitem.html" rel="nofollow">http://qt-project.org/doc/qt-4.8/qgraphicsitem.html</a><br> QPainter: <a href="http://qt-project.org/doc/qt-4.8/qpainter.html" rel="nofollow">http://qt-project.org/doc/qt-4.8/qpainter.html</a></p> <p>Cheers, Louise</p> <p>PS: First answer, yay!</p>

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.
