a GtkComboBox is, widget-wise, the same as a GtkTreeView with some magic
attached; the (old) GtkTooltips API doesn't support adding tooltips into
a GtkTreeView because the CellRenderer objects do not receive the enter
and leave notify signals.

the new tooltip API in GTK+ trunk, which should (hopefully) become GTK+
2.12 before july, will allow adding tooltips into GtkTreeView and
GtkComboBox widgets. so, you'll have to wait - and for the time being
use event boxes.

ciao,
 Emmanuele.
