Are there any examples in Go of how to use gtk.TreeModelForeachFunc to iterate over a ListStore?
I cannot seem to get the syntax right – there are exmples in c, Python, Rust, but nothing in Go!
I cannot get past compile errors.

    Liststore.ForEach(gtk.TreeModelForeachFunc func() {
        content = ""
        for i := 0; i < cols ; i++ {
            content = content + line[i]
            if i < cols -1 {
                content = content + "/t"
            } else {
                content = content + "/n"
            }
        }
        _, err := tempfile.WriteString(content)
        if err != nil {
            Logit.Fatal("Error writing to tempfile %s, error %s", "AIStemp.txt", err)
            return
        }
        return
    })

trying to iterate through a gtk.ListStore!
