<!-- $$$QAbstractTableModel-description -->
<div class="descr">
<h2>Detailed Description</h2>
<p>The QAbstractTableModel class provides an abstract model that can be subclassed to create table models.</p>
<p>QAbstractTableModel provides a standard interface for models that represent their data as a two-dimensional array of items. It is not used directly, but must be subclassed.</p>
<p>Since the model provides a more specialized interface than <a href="qabstractitemmodel.html">QAbstractItemModel</a>, it is not suitable for use with tree views, although it can be used to provide data to a <a href="qlistview.html">QListView</a>. If you need to represent a simple list of items, and only need a model to contain a single column of data, subclassing the <a href="qabstractlistmodel.html">QAbstractListModel</a> may be more appropriate.</p>
<p>The <a href="qabstractitemmodel.html#rowCount">rowCount</a>() and <a href="qabstractitemmodel.html#columnCount">columnCount</a>() functions return the dimensions of the table. To retrieve a model index corresponding to an item in the model, use <a href="qabstracttablemodel.html#index">index</a>() and provide only the row and column numbers.</p>
<a name="subclassing"></a>
<h3>Subclassing</h3>
<p>When subclassing QAbstractTableModel, you must implement <a href="qabstractitemmodel.html#rowCount">rowCount</a>(), <a href="qabstractitemmodel.html#columnCount">columnCount</a>(), and <a href="qabstractitemmodel.html#data">data</a>(). Default implementations of the <a href="qabstracttablemodel.html#index">index</a>() and <a href="qabstractitemmodel.html#parent">parent</a>() functions are provided by QAbstractTableModel. Well behaved models will also implement <a href="qabstractitemmodel.html#headerData">headerData</a>().</p>
<p>Editable models need to implement <a href="qabstractitemmodel.html#setData">setData</a>(), and implement <a href="qabstractitemmodel.html#flags">flags</a>() to return a value containing <a href="qt.html#ItemFlag-enum">Qt::ItemIsEditable</a>.</p>
<p>Models that provide interfaces to resizable data structures can provide implementations of <a href="qabstractitemmodel.html#insertRows">insertRows</a>(), <a href="qabstractitemmodel.html#removeRows">removeRows</a>(), <a href="qabstractitemmodel.html#insertColumns">insertColumns</a>(), and <a href="qabstractitemmodel.html#removeColumns">removeColumns</a>(). When implementing these functions, it is important to call the appropriate functions so that all connected views are aware of any changes:</p>
<ul>
<li>An <a href="qabstractitemmodel.html#insertRows">insertRows</a>() implementation must call <a href="qabstractitemmodel.html#beginInsertRows">beginInsertRows</a>() <i>before</i> inserting new rows into the data structure, and it must call <a href="qabstractitemmodel.html#endInsertRows">endInsertRows</a>() <i>immediately afterwards</i>.</li>
<li>An <a href="qabstractitemmodel.html#insertColumns">insertColumns</a>() implementation must call <a href="qabstractitemmodel.html#beginInsertColumns">beginInsertColumns</a>() <i>before</i> inserting new columns into the data structure, and it must call <a href="qabstractitemmodel.html#endInsertColumns">endInsertColumns</a>() <i>immediately afterwards</i>.</li>
<li>A <a href="qabstractitemmodel.html#removeRows">removeRows</a>() implementation must call <a href="qabstractitemmodel.html#beginRemoveRows">beginRemoveRows</a>() <i>before</i> the rows are removed from the data structure, and it must call <a href="qabstractitemmodel.html#endRemoveRows">endRemoveRows</a>() <i>immediately afterwards</i>.</li>
<li>A <a href="qabstractitemmodel.html#removeColumns">removeColumns</a>() implementation must call <a href="qabstractitemmodel.html#beginRemoveColumns">beginRemoveColumns</a>() <i>before</i> the columns are removed from the data structure, and it must call <a href="qabstractitemmodel.html#endRemoveColumns">endRemoveColumns</a>() <i>immediately afterwards</i>.</li>
</ul>
