<p>
The new widgets have more to offer than a mere combination of the
features of <a class="link" href="GtkOptionMenu.html" title="GtkOptionMenu"><span class="type">GtkOptionMenu</span></a> and <a class="link" href="GtkCombo.html" title="GtkCombo"><span class="type">GtkCombo</span></a>. Notable new features
include:
</p>
<div class="variablelist"><table border="0" class="variablelist">
<colgroup>
<col align="left" valign="top">
<col>
</colgroup>
<tbody>
<tr>
<td><p><span class="term">Grid mode</span></p></td>
<td><p>Sometimes it is preferable to display the available
options not in a linear list, but in a grid. A typical example
would be a "color combo" where the individual items are small
square color swatches. The new widgets support gridded display
with the functions
<a class="link" href="GtkComboBox.html#gtk-combo-box-set-wrap-width" title="gtk_combo_box_set_wrap_width ()"><code class="function">gtk_combo_box_set_wrap_width()</code></a>,
<a class="link" href="GtkComboBox.html#gtk-combo-box-set-row-span-column" title="gtk_combo_box_set_row_span_column ()"><code class="function">gtk_combo_box_set_row_span_column()</code></a> and
<a class="link" href="GtkComboBox.html#gtk-combo-box-set-column-span-column" title="gtk_combo_box_set_column_span_column ()"><code class="function">gtk_combo_box_set_column_span_column()</code></a>.
</p></td>
</tr>
<tr>
<td><p><span class="term">Display of icons</span></p></td>
<td><p>An often-heard complaint about <a class="link" href="GtkOptionMenu.html" title="GtkOptionMenu"><span class="type">GtkOptionMenu</span></a> is that
the icons which appear in the image menu items in its menu are not
displayed in the button showing the selected item. This limitation
has been removed in <a class="link" href="GtkComboBox.html" title="GtkComboBox"><span class="type">GtkComboBox</span></a>; the selected item appears in the
same way as the options in the popup.
</p></td>
</tr>
<tr>
<td><p><span class="term">Full tree model power</span></p></td>
<td><p>
Since the new widgets are built around the same models that are
used for <a class="link" href="GtkTreeView.html" title="GtkTreeView"><span class="type">GtkTreeView</span></a>, all of the powerful machinery of tree models
and cell renderers can be used.
