<para>Creates a new <link
linkend="class-gtkcellrenderercombo"><classname>gtk.CellRendererCombo</classname></link>.
Rendering parameters are adjusted using the object properties. The object
properties can be set globally (with <link
linkend="method-gobject--set-property"><methodname>set_property</methodname>()</link>).
Also, with <link
linkend="class-gtktreeviewcolumn"><classname>gtk.TreeViewColumn</classname></link>,
you can bind a property to a value in a <link
linkend="class-gtktreemodel"><classname>gtk.TreeModel</classname></link>.
For example, you can bind the "text" property on the cell renderer to a
string value in the model, thus rendering a different string in each row of
the <link
linkend="class-gtktreeview"><classname>gtk.TreeView</classname></link>.</para>

<para>
The "changed" signal is emitted each time after the user selected an item in
the combo box, either by using the mouse or the arrow keys. Contrary to GtkComboBox,
GtkCellRendererCombo::changed is not emitted for changes made to a selected item in
the entry. The argument new_iter corresponds to the newly selected item in the combo
box and it is relative to the GtkTreeModel set via the model property on GtkCellRendererCombo.
</para>
<para>
Note that as soon as you change the model displayed in the tree view, the tree view will
immediately cease the editing operating. This means that you most probably want to refrain
from changing the model until the combo cell renderer emits the edited or editing_canceled signal.
