Make window's text unique for each different button

问题

How can i make one form unique for different buttons? For example:

QVector<QString> text { "Iter FIRST", "Iter SECOND" };
for(size_t i = 0; i < 2; ++i)
{
     Form2 * form2 = new Form2(); //creating form
     connect(this, &MainWindow::SendCurretIteration, fitr, 
              &CurrentIterationForm::ShowCurrentIteration);//connect to the second form`

      emit MainWindow::SendCurretIteration(text[i]);
     QPushButton *btnShowForm = new QPushButton(this);
     btnShowForm->setGeometry(i + 40, i + 100, 50, 50);
     connect(btnShowForm, &QPushButton::clicked, this, [=]()
     {
         form2->show();
     });
}//end for()

And what i see by clicking on each button? ->Iter SECOND by clicking on button 1. ->Iter SECOND by clicking on button 2.

How to fix?
