can add to a <a href="qgraphicsscene.html">QGraphicsScene</a>.</p>
<p>QGraphicsEllipseItem respresents an ellipse with a fill and an
outline, and you can also use it for ellipse segments (see <a href="qgraphicsellipseitem.html#startAngle">startAngle</a>(), <a href="qgraphicsellipseitem.html#spanAngle">spanAngle</a>()).</p>

</tr>
</table>
<p>To set the item's ellipse, pass a <a href="qrectf.html">QRectF</a> to QGraphicsEllipseItem's constructor, or
call <a href="qgraphicsellipseitem.html#setRect">setRect</a>(). The
<a href="qgraphicsellipseitem.html#rect">rect</a>() function
returns the current ellipse geometry.</p>
<p>QGraphicsEllipseItem uses the rect and the pen width to provide
a reasonable implementation of <a href="qgraphicsellipseitem.html#boundingRect">boundingRect</a>(),
<a href="qgraphicsellipseitem.html#shape">shape</a>(), and <a href="qgraphicsellipseitem.html#contains">contains</a>(). The <a href="qgraphicsellipseitem.html#paint">paint</a>() function draws the
ellipse using the item's associated pen and brush, which you can
set by calling <a href="qabstractgraphicsshapeitem.html#setPen">setPen</a>() and <a href="qabstractgraphicsshapeitem.html#setBrush">setBrush</a>().</p>
