Hello again,
I want to add actions to an application but I can't seem to find the correct value to indicate that no parameter should be passed to a handler.
In Python, for example, I do this:
action = Gio.SimpleAction.new("about", None)
In Guile, I'm doing it like this for now:
(let [(action (make «GSimpleAction» #:name "about"))
...]
...)
But what I need to indicate is:
(make «GSimpleAction» #:name "about" #:parameter-type None)
So what's the equivalent to None in Guile?
Any help is very welcome,
---

The guile-gi equivalent would be
(set! action (simple-action:new "about"))
or
(set! action (simple-action:new "about" #f))

In this form, you'd do the following. Leaving out the #:parameter-type
from the constructor sets it to to its default of what Python would
call None.
(make <GSimpleAction> #:name "about")

Thanks for checking, Mike. I'm actually doing this (omitting #:parameter-type), but then, when I run the application and interact with something in the GUI that should trigger an action, I get the following error, and the appropriate callbacks are never run:
Backtrace:

I thought that maybe this could be related to not specifying #:paramenter-type... So I don't understand what I'm doing wrong. This is the application I'm trying to write:
https://gitlab.com/luis-felipe/geteka/-/blob/master/geteka.scm
The actions and connections are defined in the "app:activate" and "app:startup" procedures.

Well, um, the truth is that the conversion of values of type GVariant
to SCM was never implemented. I went ahead and made that fix and
pushed it into guile-gi master branch. With the fix (and after
importing TextBuffer and TextView) clicking on "Say hello!" does set
the main window to "hello" which I believe is what is intended.
Unforunately it may take time to write the unit test and then get a
new guile-gi release over to Guix.
Apologies,
Mike

No problem, Mike, thanks for working on it.
