Set full screen a dialog box

Hello all,

Could you please tell me how i can set full screen a dialog box?
I would appreciate an example :)!

Thank you!

you tried with QWidget::setWindowState()?

Example

Code:

---

this->setWindowState(Qt::WindowFullScreen);

---

Thank you its working but i can not see the close and minimize button! What i have to do?

A full screen widget doesn't have close and minimize buttons. Maybe what you wanted was a maximized window - QWidget::showMaximized().
