Hello.
If I understand you correctly, you want to store name and ID of your
field inside combo box and retrieve it when needed. If this is true,
have a look at this snippet of code that demonstrates how to do this:
-------
#include <gtk/gtk.h>
enum
{
COL_NAME,
COL_ID,
NO_COLS
};
static void
cb_changed (GtkComboBox *combo)
{
GtkTreeIter iter;
GtkTreeModel *model;
gint id;
gchar *name;
gtk_combo_box_get_active_iter (combo, &iter);
model = gtk_combo_box_get_model (combo);
gtk_tree_model_get (model, &iter, COL_NAME, &name, COL_ID, &id, -1);
g_print ("Active selection: %s (id: %d)\n", name, id);
g_free (name);
}
int
main (int argc,
char **argv)
{
GtkWidget *window,
*combo;
GtkCellRenderer *cell;
GtkListStore *store;
gint i;
gtk_init (&argc, &argv);
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
g_signal_connect (window, "destroy", gtk_main_quit, NULL);
store = gtk_list_store_new (NO_COLS, G_TYPE_STRING, G_TYPE_INT);
for (i = 0; i < 10; i++)
{
GtkTreeIter iter;
gchar name[] = "Item ";
name[5] = '0' + i;
gtk_list_store_append (store, &iter);
gtk_list_store_set (store, &iter, COL_NAME, name,
COL_ID, g_random_int (),
-1);
}
combo = gtk_combo_box_new_with_model (GTK_TREE_MODEL (store));
g_signal_connect (combo, "changed", G_CALLBACK (cb_changed), NULL);
gtk_container_add (GTK_CONTAINER (window), combo);
cell = gtk_cell_renderer_text_new ();
gtk_cell_layout_pack_start (GTK_CELL_LAYOUT (combo), cell, TRUE);
gtk_cell_layout_add_attribute (GTK_CELL_LAYOUT (combo), cell,
"text", COL_NAME);
gtk_widget_show_all (window);
gtk_main();
return 0;
}
