<h3 class="fn" id="drawItems"><a name="drawItems"></a><code>[virtual protected] </code><span class="type">void</span> QGraphicsScene::<span class="name">drawItems</span>(<span class="type"><a href="../qtgui/qpainter.html">QPainter</a></span> *<i>painter</i>, <span class="type">int</span> <i>numItems</i>, <span class="type"><a href="qgraphicsitem.html">QGraphicsItem</a></span> *[] <i>items</i>, const <span class="type"><a href="qstyleoptiongraphicsitem.html">QStyleOptionGraphicsItem</a></span>[] <i>options</i>, <span class="type"><a href="qwidget.html">QWidget</a></span> *<i>widget</i> = Q_NULLPTR)</h3>
<p>Paints the given <i>items</i> using the provided <i>painter</i>, after the background has been drawn, and before the foreground has been drawn. All painting is done in <i>scene</i> coordinates. Before drawing each item, the painter must be transformed using <a href="qgraphicsitem.html#sceneTransform">QGraphicsItem::sceneTransform</a>().</p>
<p>The <i>options</i> parameter is the list of style option objects for each item in <i>items</i>. The <i>numItems</i> parameter is the number of items in <i>items</i> and options in <i>options</i>. The <i>widget</i> parameter is optional; if specified, it should point to the widget that is being painted on.</p>
<p>The default implementation prepares the painter matrix, and calls <a href="qgraphicsitem.html#paint">QGraphicsItem::paint</a>() on all items. Reimplement this function to provide custom painting of all items for the scene; gaining complete control over how each item is drawn. In some cases this can increase drawing performance significantly.</p>
<p>Example:</p>
<pre class="cpp">

  <span class="type">void</span> CustomScene<span class="operator">::</span>drawItems(<span class="type"><a href="../qtgui/qpainter.html">QPainter</a></span> <span class="operator">*</span>painter<span class="operator">,</span> <span class="type">int</span> numItems<span class="operator">,</span>
