Invalid use of non-static member function

[Jeronimo]

Hi i am doing one little example to capture some pictures improved by me.
QPixmap captura;
captura = QScreen::grabWindow(QApplication::desktop()->winId());
But show me this:
invalid use of non-static member function

I think QApplication::desktop()->winId() is outdate?
Bye.

grabWindow is not a static function of QScreen. hence the error.

you need to get the screen from the application object and then grab it.

To add to @kenchan here is a link to QScreen documentation and there is actually an example available.
