deprecated in GTK+ 2.4 and PyGTK 2.4 in favor of the <a class="link" href="class-gtkcombobox.html" title="gtk.ComboBox"><code class="classname">gtk.ComboBox</code></a>.</p></div><p>The <a class="link" href="class-gtkcombo.html" title="gtk.Combo"><code class="classname">gtk.Combo</code></a> widget
consists of a single-line text entry field and a drop-down list. The
drop-down list is displayed when the user clicks on a small arrow button to
the right of the entry field. The drop-down list is a
<code class="classname">gtk.List</code> widget and can be accessed using the list
attribute of the <a class="link" href="class-gtkcombo.html" title="gtk.Combo"><code class="classname">gtk.Combo</code></a>. List
elements can contain arbitrary widgets, but if an element is not a plain
label, then you must use the
<code class="methodname">gtk.List.set_item_string</code>() method. This sets the
string which will be placed in the text entry field when the item is
selected.</p><p>By default, the user can step through the items in the list using
the arrow (cursor) keys, though this behavior can be turned off with the
<a class="link" href="class-gtkcombo.html#method-gtkcombo--set-use-arrows" title="gtk.Combo.set_use_arrows"><code class="methodname">set_use_arrows</code>()</a>
method. Normally the arrow keys are only active when the contents of the
text entry field matches one of the items in the list. If the contents of
the entry field do not match any of the list items, then pressing the arrow
keys does nothing. However, by calling <a class="link" href="class-gtkcombo.html#method-gtkcombo--set-use-arrows" title="gtk.Combo.set_use_arrows"><code class="methodname">set_use_arrows_always</code>()</a>
you can specify that the arrow keys are always active. If the contents of
the entry field does not match any of the items in the list, then pressing
the up or down arrow key will set the entry field to the last or first item
in the list, respectively.</p><p>Note the list attribute references a gtk.List which is a
deprecated widget so the combo widget may be changed or deprecated in the
future.</p></div><div class="refsect1" title="Constructor"><a name="constructor-gtkcombo"></a><h2>Constructor</h2><pre class="programlisting"><code class="constructorsynopsis"> <span class="methodname">gtk.Combo</span>(<span class="methodparam"></span>)</code></pre><table border="0" width="100%" bgcolor="#FFECCE"><col align="left" valign="top" width="0*"><tbody><tr><td><p><span class="term"><span class="emphasis"><em>Returns</em></span> :</span></p></td><td>a combo object*</td></tr></tbody></table><p>Creates an new <a class="link" href="class-gtkcombo.html" title="gtk.Combo"><code class="classname">gtk.Combo</code></a>
