Description Matthias Clasen 2004-07-08 21:07:21 UTC 
It has been proposed that the combo box should display a placeholder text in
this case and not pop up the empty menu/list
Comment 1 Federico Mena Quintero 2004-07-09 01:35:23 UTC 
gtk_combo_box_set_empty_text (combo_box, "No items"), perhaps?

The GIMP people may have other thoughts about this; CCing Sven.
Comment 2 Sven Neumann 2004-07-09 06:29:39 UTC 
Yes, that API should be sufficient for our needs.
Comment 3 Matthias Clasen 2004-07-09 18:52:38 UTC 
But it is not so simple, since we can have arbitrary cell renderers. It is not
even guaranteed that there is a text cell renderer at all...
Comment 4 Sven Neumann 2005-02-27 21:21:09 UTC 
Allow a special value in the associated tree-model then? And wrap this for the
simple text-only combo box?
Comment 5 Murray Cumming 2007-05-04 20:52:25 UTC 
Bug #382291 suggests that the GtkComboBox should just be dimmed when it is empty. But it would be nice to sometimes set some text to show. I guess a real-world example would be more compelling.
Comment 6 Sven Herzberg 2008-02-11 14:42:25 UTC 
Would it be te total overkill to be able to supply an "empty-model" of which the first row would be displayed? I cannot actually think of an easier way to be able to support any cell layout.
Comment 7 Daniel Boles 2017-03-03 14:30:59 UTC 
It doesn't pop up an empty list anymore, since Bug 382291 was resolved, which desensitises the ComboBox for a 0-length model.

It still pops up for a 1-item list, though, which isn't very useful; I opened Bug 775539 for that.

anyway, a placeholder model seems like something best left to the user, no?
