Re: Combined search and combobox?
Indeed, you were right regarding gtk_comb_box_set_entry_text_column().
For the record, below find a translation into C of your python program.
Here are some enhancements that I thought of, though I highly doubt that
they will be adapted because they are too specialized.
- Turn it into a widget, that takes a receives of strings in its
constructor.
- Add keybindings for the following functionality:
- Restore the last string input into the entry widget before
selecting a match i the combo-box. E.g. [Meta-Up], [Ctrl-/]
- Select next entry matching the last string input. [Ctrl-Up]
- Select previous entry matching the last string input. [Ctrl-Down]
- Toggle mathing method between Regular expressions, and partial
string matches. [Ctrl-=]
- The special keybindings should also be shown when doing rightclick in
the enty widget, that should allow the above functionality.
Based on the code below, I have now also created a pull request for
gucharmap: https://github.com/GNOME/gucharmap/pull/2 .
Thanks again!

Re: Combined search and combobox?
I agree that setting this up is a bit too complex, and it would be nice if there was a standalone widget that this everything for you. Meanwhile I tried converting your widget into C (with the intention of replacing the font selection widget in gucharmap), and something is not working. I get lots of warnings about: (gucharmap:30880): Gtk-CRITICAL **: 17:41:07.804: gtk_entry_set_text: assertion 'text != NULL' failed This happens e.g. when I'm using the up down arrows within the text entry.

Re: Combined search and combobox?
Thanks. This is exactly what I was looking for! I didn't realize that a
combobox can be attached to a model, and that a model can be filtered.
Imo multiple partial string match should be default behavior, which it is
unfortunately not. E.g. inkscape only matches in the beginning of the
string.
Is there a GNOME guide line about this?

A use case would be to search for a fontname in a very long font list.
I would like to be able to type a search string, and have the opened
combobox display only entries that match the typed string. A plus
would be if it is possible to change how matches take place, e.g.
between multiple word (like helm-mode in emacs), a regular expression,
or an absolute match.
Has someone written anything like that?
You didn't specify a language, so here's an example in Python. It uses
space separated keywords, like in Google search or so. It may not be
exactly as you requested, but will give you something to start with.

combo.set_entry_text_column(0)
combo.connect('changed', self.changed)
#completion
completion = Gtk.EntryCompletion ()
completion.set_model(self.model)
completion.set_text_column(0)
completion.set_match_func(self.match_func)
completion.connect ('match-selected', self.match_selected)
#combobox entry
entry = combo.get_child()

Combined search and combobox?
Is there a widget that combines a searchbox with a combobox? A use case would be to search for a fontname in a very long font list. I would like to be able to type a search string, and have the opened combobox display only entries that match the typed string. A plus would be if it is possible to change how matches take place, e.g. between multiple word (like helm-mode in emacs), a regular expression, or an absolute match.
