How to add rows in StandardTableView component in C++

[Sonnvu]

I'm trying to populate data into the StandardTableView component and relating to disccusion #5298, it is advised to use VecModel::push to add new row to model. Is there a way to achieve that in C++?

MainWindow.slint code:

import { StandardTableView } from "std-widgets.slint";
component MainWindow inherits Rectangle {
    in-out property <[[StandardListViewItem]]> row_data: [
        [ { text: "Item 1.1" }, { text: "Item 1.2" }, { text: "Item 1.3" } ],
    ];
    callback add_row();

    StandardTableView {
        columns: [
            { title: @tr("Column 1") },
            { title: @tr("Column 2") },
            { title: @tr("Column 3") },
        ];
        rows: row_data;
    }
    Button {
        text: "Add Row";
        clicked => {root.add_row()}
    }
}

Cpp code:

int main(void)
{
    auto main_ui = MainWindow::create();
    main_ui->on_add_row([&] () {
        std::vector<std::vector<std::string> row_data;    // Trying to create model for StandardTableView's row but it's not the right type
        main_ui->set_row_data(row_data);
    })
    main_ui->run();
}

To push new entry into the row model for StandardTableView component, how can I create the right structure type for 'row_data' in C++?

Thanks!

I believe the row_data is supposed to be of the type std::shared_ptr<slint::Model<slint::StandardListViewItem>>>>

You can make one for example with
std::make_shared<slint::VecModel<slint::StandardListViewItem>>(.....)

Thank you for your reply!

It seems that the type for row_data is still an issue as I try to populate the StandardTableView by creating the vector model row_data:
slint::VectorModel<slint::StandardListViewItem> row_data;

And share that model upfront:
auto row_data_model = std::make_shared<slint::VectorModel<slint::StandardListViewItem>>(row_data);
main_ui->set_row_data(row_data_model);

The error says

cannot convert std::shared_ptr<slint::VectorModel<slint::StandardListViewItem> > to const std::shared_ptr<slint::Model<std::shared_ptr<slint::Model<slint::StandardListViewItem> > > >&

The model slint::VectorModel<slint::StandardListViewItem> does work for the StandardListView component though
