<!-- ##### SECTION Title ##### -->
GnomeDbCombo

<!-- ##### SECTION Short_Description ##### -->
A combo box with data to be displayed as a #GdaDataModel

<!-- ##### SECTION Long_Description ##### -->
<para>
This widget acts like the #GtkComboBox widget which it inherits, 
but displays data from a provided #GdaDataModel
and it is easy to set the currently selected row or retrieve values of the currently selected row.
</para>
<para>
Specifically it is possible to show only some columns of the data model when using the
gnome_db_combo_new_with_model() and gnome_db_combo_set_model() functions by passing these functions
an array of integers (containing the column number of each column to display), and the size of
that array.
