How did you open the windows? Can you set the focus with mouse?

the two windows are login form and mainscene i use this code to open the mainscene form from login scene

Code:

---

MainScene* w = new MainScene(this);
    //this->close();
    w->showFullScreen();

---

i can change focus by mouse only and touch on the device
thanks
