Сохранение данных приложения после закрытия

как сохранить данные приложения после закрытие и как сортировать лист по имени если имена одинаковые то по дате рождения,заранее спасибо

задача примерно таккая:

Write a program with a well designed, developed and tested GUI, which can handle and show information about bank accounts and clients. The GUI provide facilities to add new clients with their data, like name, date of birth, unique client identifier (program generates and fills up automatically), account number (2x8 digits) and balance. So the user can add new client, modify and delete the existent items via GUI if he/she wants it. The software can handle the all possible exception and gives any information about them for the users. The GUI is contained a list view in where the clients are sorted according to their names and date of birth (if the names are equals). The user can filter the clients based on the amount of their money. The software save the collected data into file before closing and load back when it starts.

Ничерта не понял, что у тебя за задача, но, полагаю, это реализуется через переопределение QCloseEvent:

void MainWindow::closeEvent(QCloseEvent *e)
{
    {
        QMessageBox::StandardButton askBtn = QMessageBox::question(this, "Выход" ,tr("Действительно хотите выйти?"), QMessageBox::Yes | QMessageBox::No, QMessageBox::Yes);
        if (askBtn == QMessageBox::Yes)
        {
                e->accept();
        }
       if (askBtn == QMessageBox::No)
            e->ignore();
    }
    else
        e->ignore();
}
