Hi,

Are you using Gtk2? if yes this is my way!


GtkWidget *lista;
GtkTreeSelection *select;

select = gtk_tree_view_get_selection (GTK_TREE_VIEW (lista));
gtk_tree_selection_set_mode (select, GTK_SELECTION_MULTIPLE);
g_signal_connect (G_OBJECT (select),"changed",
                  G_CALLBACK(select_change), NULL);


Then the callback function:

static void select_change(GtkTreeSelection *selection, gpointer data){
        //Use the GtkTreeSelection object to retrive the information you
        //need
}       


Hope you find my example useful...
