<p>This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.</p>
<p>Returns <code>true</code> if this item handles child events (i.e&#x2e;, all events intended for any of its children are instead sent to this item); otherwise, false is returned.</p>
<p>This property is useful for item groups; it allows one item to handle events on behalf of its children, as opposed to its children handling their events individually.</p>
<p>The default is to return false; children handle their own events. The exception for this is if the item is a <a href="qgraphicsitemgroup.html">QGraphicsItemGroup</a>, then it defaults to return true.</p>

<p>Rotates the current item transformation <i>angle</i> degrees clockwise around its origin. To translate around an arbitrary point (x, y), you need to combine translation and rotation with <a href="qgraphicsitem.html#setTransform">setTransform</a>().</p>
