Question

I am new to Qt.

I am doing a project using Qt Creator. In my project, I have one mainWindow. From the main window I start 4 screens (one after another, showing Initialization process). A new QDialog screen is opened, if there are any errors on any screen. My error screens have two Button (Retry, Continue). If i press Retry, i have to restart the initialization process over again.
eg;

void ErrorScreen1::on_Retry_pressed()
{
    Screen1 *scrn = new Screen1(this); 
    scrn->show();
    this->close();
}

In above example, it restarts the process.

Is there any way, I can start the initialization process from the point it was left?

Thanks in advance,

I resolved this issue by using QMessageBox as my error window.

It allowed me to start my process from the point i left.

void Screen1::ErrorMessage()
{
    timer->stop();

    QMessageBox *msgbox = new QMessageBox(this);
    msgbox->setWindowTitle("ERROR MESSAGE");
    msgbox->setText("Initialization Failed.");
    msgbox->setStandardButtons(QMessageBox::Cancel | QMessageBox::Retry);
    msgbox->setDefaultButton(QMessageBox::Retry);

    int ret = msgbox->exec();

    switch (ret)
    {
        case QMessageBox::Retry: timer->start(); break;

        case QMessageBox::Cancel:
            timer->disconnect();
            ui->progressBar->setValue(0);
            break;

        default: break;

    }
}
