Call pas.exec(); instead of pas.show();

[smemamian]

ok, but when i click on ok button, the user and pass window does not close ! Then when I close the user and pass window manually, The main window opens.

[amleto]

void setPass::on_pushButton_clicked()
{
    setUsername(user = ui->userName->text());
    setPassword( pass = ui->passWord->text());
    accept(); // <<<<<<<<<<<<
}

void setPass::on_pushButton_clicked()
{
    setUsername(user = ui->userName->text());
    setPassword( pass = ui->passWord->text());
    accept(); // <<<<<<<<<<<<
}

Make up your mind...

[wysota]

Why wouldn't it be closed?

@amleto: I think he doesn't want to close the dialog until the user explicitly requests so. Which doesn't make much sense but I think that's OP's idea...

going back to this

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
 
    setPass pas ;
    pas.show();
    if(pas.setBool())
    {
    MainWindow w;
    pas.close();
    w.show();
    }
    //  what do you think has happened to 'w' here?  Answer: it does not exist.
    return a.exec();
}

i changed :

void setPass::on_pushButton_clicked()
{
    setUsername(user = ui->userName->text());
    setPassword( pass = ui->passWord->text());
    if(setBool())
    accept();
}

void setPass::on_pushButton_clicked()
{
    setUsername(user = ui->userName->text());
    setPassword( pass = ui->passWord->text());
    if(setBool())
    accept();
}
