I Noticed an anti-intuitive thing.
Once I've selected a value in a combo box, I can't "reset" it (from an
user's POV). Is there a reason not to handle an "esc" press on it to
call ...set_active(this, -1) ? I know I can do it myself in my programs,
but IMVHO it should be done by the library.
Why would you want to "reset" a combo box from the user interface? Even
if one ignores the fact that such a change would (possibly) break quite
a lot of applications, it doesn't seem to be very useful at all. If an
application offers a "reset"-state to the user, it'll usually include a
"None"/"Disabled" item in the combobox' model.
Then Gtk should ENFORCE that by selecting the first row of the model.
I'm using a model filled from a DB and it's quite useful to have the
current behaviour PLUS "esc" management. And it's orthogonal (think a
box that lets you select an user from a list, or "nothing" to broadcast:
now, once you've selected a user you can't rethink and send to all). IMO
the current behaviour is the safest (a row in the model gets accessed
only when the user wants to), and adding "esc" handling shouldn't break
anything. A complete solution would require API changes
(gtk_combo_box_set_default_selection() ?) to be done really well, but
calling gtk_combo_box_set_active(this, -1) should be quite safe.
