GtkComboBox and focus-in-event

["Antonio Scuri" <scuri tecgraf puc-rio br>]

  Hi,

  I would like to use the "focus-in-event" and "focus-out-event" for
GtkComboBox. But the signals were not called. Then I added a GtkEventBox as
parent so it works for a while. But on recent GTK versions it stopped
working.

  Any clues?

Thanks in Advance,
