Signal emitted when changing a combo selection?

[Markus Gerwinski <markus gerwinski de>]

Hi folks,

I've got a problem with Gtkmm that seems to lead back to GTK. (See forwarded
message below.) Maybe someone can help me here?

Thanks in advance,

  Markus

After some tests, I found out the combo->get_list().signal_unmap() seems to be
never called... which is a pity, since it could possibly help me solve another
problem: The combo->get_entry().signal_changed() is always emitted twice if
changing from a non-empty string to another one.

Example: Combo changes from "Mr." to "Ms" using the dropdown list. Then I get
two signals:

  signal_changed: "Mr." -> ""
  signal_changed: "" -> "Ms."

This is a serious problem for me, since it tangles up my `undo' stack, doubles
the number of database queries etc.. Is there a proper way to solve this?
