29 * @Title: GtkComboBoxText
30 * @See_also: @GtkComboBox
32 * A GtkComboBoxText is a simple variant of #GtkComboBox that hides
33 * the model-view complexity for simple text-only use cases.
35 * To create a GtkComboBoxText, use gtk_combo_box_text_new() or
36 * gtk_combo_box_text_new_with_entry().
38 * You can add items to a GtkComboBoxText with
39 * gtk_combo_box_text_append_text(), gtk_combo_box_text_insert_text()
40 * or gtk_combo_box_text_prepend_text() and remove options with
41 * gtk_combo_box_text_remove().
