How to use GTK 4 GridView with gio.ListStore and gtk.BuilderListItemFactory

[diamondburned]

You can't create an object like that. gotk4 unfortunately doesn't support subclassing.

You could try to use gioutil.ListModel[T].

This isn't really an answer, because I'm only currently working with strings, but I'm going through a similar process of trying to get model binding working with the dynamic GTK4 gridviews. In case it's helpful, I've got a version of your code working using a backing gtk.StringList, rather than the gio.ListStore:

Rather than calling gio.NewListStore and then appending an item to it, I create a StringList with:

store := gtk.NewStringList([]string{"Test 1", "Test 2"})

and then the only other relevant change is the data binding, so replacing <lookup name="label"> with <lookup name="string" type="GtkStringObject">.

After that, I get a view that shows two text labels as expected ("Test 1" and "Test 2").

I'll also need to build a more complex / custom data model, so I'll keep working on this, too.
