Refer to the Qt documentation of QAbstractItemModel::index

fn parent(&self, index: QModelIndex) -> QModelIndex

Refer to the Qt documentation of QAbstractItemModel::parent

fn row_count(&self, parent: QModelIndex) -> i32

Refer to the Qt documentation of QAbstractItemModel::rowCount

fn column_count(&self, parent: QModelIndex) -> i32
