<!-- $$$reset[overload1]$$$reset -->
<h3 class="fn" id="reset"><a name="reset"></a><code>[protected] </code><span class="type">void</span> QAbstractItemModel::<span class="name">reset</span>()</h3>
<p>Resets the model to its original state in any attached views.</p>
<p>This function emits the signals <a href="qabstractitemmodel.html#modelAboutToBeReset">modelAboutToBeReset</a>() and <a href="qabstractitemmodel.html#modelReset">modelReset</a>().</p>
<p><b>Note: </b>Use <a href="qabstractitemmodel.html#beginResetModel">beginResetModel</a>() and <a href="qabstractitemmodel.html#endResetModel">endResetModel</a>() instead whenever possible. Use this method only if there is no way to call <a href="qabstractitemmodel.html#beginResetModel">beginResetModel</a>() before invalidating the model. Otherwise it could lead to unexpected behaviour, especially when used with proxy models.</p><p>For example, in this code both signals <a href="qabstractitemmodel.html#modelAboutToBeReset">modelAboutToBeReset</a>() and <a href="qabstractitemmodel.html#modelReset">modelReset</a>() are emitted <i>after</i> the data changes:</p>
<pre class="cpp">
myData<span class="operator">.</span>clear();
reset();
</pre>
<p>Instead you should use:</p>
<pre class="cpp">
beginResetModel();
myData<span class="operator">.</span>clear();
endResetModel();
</pre>

<!-- $$$setRoleNames[overload1]$$$setRoleNamesconstQHash<int,QByteArray>& -->
<h3 class="fn" id="setRoleNames"><a name="setRoleNames"></a><code>[protected] </code><span class="type">void</span> QAbstractItemModel::<span class="name">setRoleNames</span>(const <span class="type"><a href="qhash.html">QHash</a></span><<span class="type">int</span>, <span class="type"><a href="qbytearray.html">QByteArray</a></span>> &<i>roleNames</i>)</h3>
<p>This function is obsolete. Reimplement <a href="qabstractitemmodel.html#roleNames">roleNames</a>() instead.</p>
<p>Sets the model's role names to <i>roleNames</i>.</p>
<p>This function allows mapping of role identifiers to role property names in scripting languages.</p>
<p>This function was introduced in Qt 4.6.</p>
<p><b>See also </b><a href="qabstractitemmodel.html#roleNames">roleNames</a>().</p>

<p>This function is obsolete. Reimplement <a href="qabstractitemmodel.html#supportedDragActions">supportedDragActions</a>() instead.</p>
<p>Sets the supported drag <i>actions</i> for the items in the model.</p>
<p>This function was introduced in Qt 4.2.</p>
<p><b>See also </b><a href="qabstractitemmodel.html#supportedDragActions">supportedDragActions</a>() and <a href="../qtwidgets/model-view-programming.html#using-drag-and-drop-with-item-views">Using drag and drop with item views</a>.</p>
