<div class="refsect1">
<a name="GtkCellLayout.description"></a><h2>Description</h2>
<p><a class="link" 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 <a class="link" href="GtkTreeViewColumn.html" title="GtkTreeViewColumn"><span class="type">GtkTreeViewColumn</span></a> like API for packing cells,
setting attributes and data funcs.</p>
<p>One of the notable features provided by implementations of
GtkCellLayout are attributes. 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 class="link" href="GtkCellLayout.html#gtk-cell-layout-set-attributes" title="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 class="link" href="GtkCellLayout.html#gtk-cell-layout-set-cell-data-func" title="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.</p>
<div class="refsect2">
<a name="id-1.3.12.13.9.4"></a><h3>GtkCellLayouts as GtkBuildable</h3>
<p>Implementations of GtkCellLayout which also implement the GtkBuildable
interface (<a class="link" href="GtkCellView.html" title="GtkCellView"><span class="type">GtkCellView</span></a>, <a class="link" href="GtkIconView.html" title="GtkIconView"><span class="type">GtkIconView</span></a>, <a class="link" href="GtkComboBox.html" title="GtkComboBox"><span class="type">GtkComboBox</span></a>,
<a class="link" href="GtkEntryCompletion.html" title="GtkEntryCompletion"><span class="type">GtkEntryCompletion</span></a>, <a class="link" href="GtkTreeViewColumn.html" title="GtkTreeViewColumn"><span class="type">GtkTreeViewColumn</span></a>) accept GtkCellRenderer objects
as <child> elements in UI definitions. They support a custom <attributes>
element for their children, which can contain multiple <attribute>
elements. Each <attribute> element has a name attribute which specifies
a property of the cell renderer; the content of the element is the
attribute value.</p>
<p>This is an example of a UI definition fragment specifying attributes:</p>

<p>Furthermore for implementations of GtkCellLayout that use a <a class="link" href="GtkCellArea.html" title="GtkCellArea"><span class="type">GtkCellArea</span></a>
to lay out cells (all GtkCellLayouts in GTK+ use a GtkCellArea)
cell properties can also be defined in the format by
specifying the custom <cell-packing> attribute which can contain multiple
<property> elements defined in the normal way.</p>

<p>When subclassing a widget that implements <a class="link" href="GtkCellLayout.html" title="GtkCellLayout"><span class="type">GtkCellLayout</span></a> like
<a class="link" href="GtkIconView.html" title="GtkIconView"><span class="type">GtkIconView</span></a> or <a class="link" href="GtkComboBox.html" title="GtkComboBox"><span class="type">GtkComboBox</span></a>, there are some considerations related
to the fact that these widgets internally use a <a class="link" href="GtkCellArea.html" title="GtkCellArea"><span class="type">GtkCellArea</span></a>.
The cell area is exposed as a construct-only property by these
widgets. This means that it is possible to e.g. do</p>

<p>to use a custom cell area with a combo box. But construct properties
are only initialized after instance <code class="function">init()</code>
functions have run, which means that using functions which rely on
the existence of the cell area in your subclass’ <code class="function">init()</code> function will
cause the default cell area to be instantiated. In this case, a provided
construct property value will be ignored (with a warning, to alert
you to the problem).</p>
