How to use model from nested string array?

[qarmin]

With this slint file

export component MainWindow {
    in-out property <[[string]]> empty-folder-model: [
        ["kropkarz", "/Xd1", "24.10.2023"] ,
        ["witasphere", "/Xd1/Imagerren2", "25.11.1991"] ,
        ["lokkaler", "/Xd1/Vide2", "01.23.1911"] ,
];
}

I'm unable to set it from rust

My code attempts - set_empty_folder_model expects ModelRc<ModelRc<slint::SharedString>> and I don't know how to create it from rust

    let app = MainWindow::new().unwrap();//.run().unwrap();
    let row_data: Rc<VecModel<VecModel<SharedString>>> = Rc::new(VecModel::default());

    for r in 0..101 {
        let items = VecModel::default();

        for c in 0..3 {
            items.push(slint::format!("Item {r}.{c}").into());
        }

        // dbg!(&items);
        // row_data.push(items.clone());
        row_data.push(items.into());
        // row_data.push(items.into());
        // row_data.row_data().push(items.into());
    }

    // let row_data: ModelRc<ModelRc<SharedString>> = ModelRc::from(Rc::new(VecModel::from(
    //     vec![
    //         slint::format!("Item 1").into(),
    //          slint::format!("Item 2").into(),
    //         slint::format!("Item 4").into()])));
    app.set_empty_folder_model();

    app.run().unwrap();

30    |     app.set_empty_folder_model();
      |         ^^^^^^^^^^^^^^^^^^^^^^-- an argument of type `ModelRc<ModelRc<slint::SharedString>>` is missing

you need to build a VecModel<ModelRc<SharedString>>

So something like (untested)

   let app = MainWindow::new().unwrap();//.run().unwrap();
    let row_data: Rc<VecModel<ModelRc<SharedString>>> = Rc::new(VecModel::default());
//                            ^^^^^^^ changed to ModelRc

    for r in 0..101 {
        let items = VecModel::default();

        for c in 0..3 {
            items.push(slint::format!("Item {r}.{c}").into());
        }

        row_data.push(ModelRc::new(items));
    }

    app.set_empty_folder_model(row_data.into());

    app.run().unwrap();
