Hello Guile Users!
I am trying to use G-Golf to create a tree view (the thing that looks like a
table) and for that purpose to create a GtkListStore instance.
The GTK4 docs at
https://docs.gtk.org/gtk4/section-tree-widget.html#creating-a-model tell me,
that I need to create the store. A simple list store should be sufficient for my
purpose for now. The example code they give is:
~~~~
|GtkListStore*store=gtk_list_store_new(2,G_TYPE_STRING,G_TYPE_BOOLEAN);|
~~~~
I am assuming, that using G-Golf I also need to specify the types of the columns
somehow. I've not yet found a G-Golf example for using a TreeView, but I am
asuming, that the constructor call is something like:
~~~~
(eval-when (expand load eval)
(use-modules (oop goops))
(default-duplicate-binding-handler
'(merge-generics replace warn-override-core warn last))
(use-modules (g-golf))
(g-irepository-require "Gtk" #:version "4.0")
(for-each (λ (name) (gi-import-by-name "Gtk" name))
'(...
"ListStore")))
(define my-list-store (make <gtk-list-store> 2 G_TYPE_STRING, G_TYPE_BOOLEAN))
~~~~
The import of "ListStore" seems to work fine, does not produce an error at
least. But "G_TYPE_STRING" and "G_TYPE_BOOLEAN" are missing, unbound
identifiers.
https://www.gnu.org/software/g-golf/manual/html_node/Naming-Conventions.html
does not list such things. Maybe under Enums, Flags and boxed types, but I am
not sure. And running something like:
~~~~
(gi-import-by-name "Gtk" "G_TYPE_STRING")
~~~~
did not work either. I am thinking that is, because those things are not defined
in GTK, but elsewhere.
(1) Is my constructor call correct? Do I need to pass those type indicators? I
guess so, because how else is the underlying GTK going to get that info?
(2) How to import the "type indicators"?
Best regards,
Zelphir
