<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qabstractproxymodel.html">QAbstractProxyModel</a> class provides a base class for proxy item models that can do sorting, filtering or other data processing tasks.</p>
<p>This class defines the standard interface that proxy models must use to be able to interoperate correctly with other model/view components. It is not supposed to be instantiated directly.</p>
<p>All standard proxy models are derived from the <a href="qabstractproxymodel.html">QAbstractProxyModel</a> class. If you need to create a new proxy model class, it is usually better to subclass an existing class that provides the closest behavior to the one you want to provide.</p>
<p>Proxy models that filter or sort items of data from a source model should be created by using or subclassing <a href="qsortfilterproxymodel.html">QSortFilterProxyModel</a>.</p>
<p>To subclass <a href="qabstractproxymodel.html">QAbstractProxyModel</a>, you need to implement <a href="qabstractproxymodel.html#mapFromSource">mapFromSource</a>() and <a href="qabstractproxymodel.html#mapToSource">mapToSource</a>(). The <a href="qabstractproxymodel.html#mapSelectionFromSource">mapSelectionFromSource</a>() and <a href="qabstractproxymodel.html#mapSelectionToSource">mapSelectionToSource</a>() functions only need to be reimplemented if you need a behavior different from the default behavior.</p>
<p><b>Note: </b>If the source model is deleted or no source model is specified, the proxy model operates on a empty placeholder model.</p></div>
