GtkCombo

a text entry field with a dropdown list.

<para>
|
|
The #GtkCombo 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.
|
|
</para>
|
|
<para>
|
|
The drop-down list is a #GtkList widget and can be accessed using the
|
|
<structfield>list</structfield> member of the #GtkCombo-struct.
|
|
List elements can contain arbitrary widgets, but if an element is not a
|
|
plain label, then you must use the gtk_list_set_item_string() function.
|
|
This sets the string which will be placed in the text entry field when the
|
|
item is selected.
|
|
</para>
|
|
<para>
|
|
By default, the user can step through the items in the list using the
|
|
arrow (cursor) keys, though this behaviour can be turned off with
|
|
gtk_combo_set_use_arrows().
|
|
</para>

As of GTK+ 2.4, #GtkCombo has been deprecated in favor of #GtkComboBox.
