Hello
When I run this program, instead of showing me a list of 3 rows, the treeview is showing me only 1 row. I'm guessing the iter is not pointing to the new row in buildModel()? If not, what's causing this?

int main(string[] args) {
    import gtk.Application : Application;
    import gtkc.gtktypes : GApplicationFlags;
    import gio.Application : GioApp = Application;

    auto app = new Application("org.gtkdnotes.cellrenders", GApplicationFlags.FLAGS_NONE);

    app.addOnActivate(delegate void(GioApp _) {
        import gtk.ApplicationWindow : ApplicationWindow;

        auto aw = new ApplicationWindow(app);
        scope (success)
            aw.showAll();

        aw.setDefaultSize(320, 200);
        aw.setTitle("CellRendererText Example");
        aw.add(buildUi());
    });

    return app.run(args);
}

enum Columns {
    TEXT,
    EDITABLE_TEXT
}

import gtk.Box : Box;
import gtk.TreeView : TreeView;

Box buildUi() {
    import gtkc.gtktypes : GtkOrientation;

    auto vbox = new Box(GtkOrientation.VERTICAL, 5);

    vbox.packStart(buildView(buildModel), true, true, 0);

    return vbox;
}

import gtk.ListStore : ListStore;

ListStore buildModel() {
    import gtk.ListStore : ListStore;
    import gtkc.gobjecttypes : GType;

    auto ls = new ListStore([GType.STRING, GType.STRING]);

    import gtk.TreeIter : TreeIter;

    auto ti = ls.createIter();

    ls.setValue(ti, Columns.TEXT, "Arch");
    ls.setValue(ti, Columns.EDITABLE_TEXT, "https://www.archlinux.org/");
    ls.setValue(ti, Columns.TEXT, "Debian");
    ls.setValue(ti, Columns.EDITABLE_TEXT, "https://www.debian.org/");
    ls.setValue(ti, Columns.TEXT, "Fedora");
    ls.setValue(ti, Columns.EDITABLE_TEXT, "https://getfedora.org/");

    return ls;
}

TreeView buildView(ListStore ls) {
    import gtk.CellRendererText : CellRendererText;

    auto tv = new TreeView();

    import gtk.TreeViewColumn : TreeViewColumn;

    tv.appendColumn(new TreeViewColumn("Text", new CellRendererText(), "text", Columns.TEXT));

    auto cellRendererEditableText = new CellRendererText();
    cellRendererEditableText.setProperty("editable", true);
    tv.appendColumn(new TreeViewColumn("Editable text",
            cellRendererEditableText, "text", Columns.EDITABLE_TEXT));

    tv.setModel(ls);

    return tv;
}
