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
QAbstractProxyModel 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 QAbstractProxyModel, 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>
