typedef gint (*GtkCListCompareFunc) (GtkCList     *clist,
				     gconstpointer ptr1,
				     gconstpointer ptr2);

/* sets a compare function different to the default */
void gtk_clist_set_compare_func (GtkCList            *clist,
				 GtkCListCompareFunc  cmp_func);

For example, I use this in memprof:

====================
static gint
profile_compare_name (GtkCList     *clist,
		      gconstpointer ptr1,
		      gconstpointer ptr2)
{
	ProfileFunc *func1 = ((const GtkCListRow *)ptr1)->data;
	ProfileFunc *func2 = ((const GtkCListRow *)ptr2)->data;

	return strcmp (func1->symbol->name, func2->symbol->name);
}

[...]

static void
profile_func_click_column (GtkWidget *clist, gint column)
{
	static const GtkCListCompareFunc compare_funcs[] = {
		profile_compare_name,
		profile_compare_self,
		profile_compare_total
	};

	g_return_if_fail (column >= 0 && column < 3);

	gtk_clist_set_compare_func (GTK_CLIST (clist), compare_funcs[column]);
	gtk_clist_sort (GTK_CLIST (clist));
}
===================

The 'ProfileFunc *' structure is set as row data on each row
in the CList.

Hope this helps,
