<a name="id3208480"></a><h2>Description</h2>
<p>
<a href="GtkCellLayout.html" title="GtkCellLayout"><span class="type">GtkCellLayout</span></a> is an interface to be implemented by all objects which
want to provide a <span class="type">GtkTreeViewColumn-like</span> API for packing cells, setting
attributes and data funcs.
</p>
<p>
One of the notable features provided by implementations of GtkCellLayout
are <span class="emphasis"><em>attributes</em></span>. Attributes let you set the properties
in flexible ways. They can just be set to constant values like regular
properties. But they can also be mapped to a column of the underlying
tree model with <a href="GtkCellLayout.html#gtk-cell-layout-set-attributes"><code class="function">gtk_cell_layout_set_attributes()</code></a>, which means that the value
of the attribute can change from cell to cell as they are rendered by the
cell renderer. Finally, it is possible to specify a function with
<a href="GtkCellLayout.html#gtk-cell-layout-set-cell-data-func"><code class="function">gtk_cell_layout_set_cell_data_func()</code></a> that is called to determine the value
of the attribute for each cell that is rendered.

Adds an attribute mapping to the list in <em class="parameter"><code>cell_layout</code></em>. The <em class="parameter"><code>column</code></em> is the
column of the model to get a value from, and the <em class="parameter"><code>attribute</code></em> is the
parameter on <em class="parameter"><code>cell</code></em> to be set from the value. So for example if column 2
of the model contains strings, you could have the "text" attribute of a
<a href="GtkCellRendererText.html" title="GtkCellRendererText"><span class="type">GtkCellRendererText</span></a> get its values from column 2.</p>
