<div class="descr">
<h2>Detailed Description</h2>
<p>The QGraphicsObject class provides a base class for all graphics items that require signals, slots and properties.</p>
<p>The class extends a <a href="qgraphicsitem.html">QGraphicsItem</a> with <a href="qobject.html">QObject</a>'s signal/slot and property mechanisms. It maps many of <a href="qgraphicsitem.html">QGraphicsItem</a>'s basic setters and getters to properties and adds notification signals for many of them.</p>
<a name="parents-and-children"></a>
<h3>Parents and Children</h3>
<p>Each graphics object can be constructed with a parent item. This ensures that the item will be destroyed when its parent item is destroyed. Although QGraphicsObject inherits from both <a href="qobject.html">QObject</a> and <a href="qgraphicsitem.html">QGraphicsItem</a>, you should use the functions provided by <a href="qgraphicsitem.html">QGraphicsItem</a>, <i>not</i> <a href="qobject.html">QObject</a>, to manage the relationships between parent and child items.</p>
<p>The relationships between items can be explored using the <a href="qgraphicsitem.html#parentItem">parentItem</a>() and <a href="qgraphicsitem.html#childItems">childItems</a>() functions. In the hierarchy of items in a scene, the <a href="qgraphicsitem.html#parentObject">parentObject</a>() and <a href="qgraphicsitem.html#parentWidget">parentWidget</a>() functions are the equivalent of the <a href="qobject.html#parent">QWidget::parent</a>() and <a href="qwidget.html#parentWidget">QWidget::parentWidget</a>() functions for <a href="qwidget.html">QWidget</a> subclasses.</p>
