Yes I also find that this function is in new versions (>4).

 

For capturing the output screen I found this on QT mailing list and it works:

QPixmap::grabWindow(widget->winId()).save("filename", "PNG");

Indeed, there is no such function 'render' in Qt3's QWidget.

Anyway, CGAL::Qt_widget has a documented function get_pixmap(), that gives you
a pixmap of the widget's viewport. See the documentation:
