    Ruth,

    1. SVG - yes, these properties are really missing, this is a pure bug; I'll take a look tonight;
    2. setOverrideCursor - this method is gone in Qyoto because I merge all get/set methods into C# properties; that is, you've correctly found out that QApplication.OverrideCursor is the substitute to use. About QApplication.OverrideCursor = Qt.CursorShape.WaitCursor; , apparently PyQt has a convenient implicit conversion operator because otherwise this isn't supposed to work. If you look at the Qt docs for QApplication::setOverrideCursor you'll see:
        QApplication::setOverrideCursor(QCursor(Qt::WaitCursor));
    That is, you need to pass a QCursor, not just an enum value. In Qyoto this would look like:
        QApplication.OverrideCursor = new QCursor(Qt.CursorShape.WaitCursor);
    3. QGraphicsItem.Scale has two overloads; the one with 0 parameters is not obsolete but the one with 2 is (Qt 4.8.4). The comment there hasn't been generated well because I use regular expressions to extract the documentation and apparently there are come cases I do not handle well yet. Anyway, the substitute is setTransform(QTransform::fromScale(sx, sy), true).

    Regards,
    Dimitar Dobrev

Many thanks for your quick response Dimitar.

To be more explicit, the SVG properties I am using are Filename,
    Size, Title and Description. The missing Filename property, in
    particular, makes the class useless as it is used to set the output
    file.

I am also having trouble getting this line, which used to work in
    PyQt, to compile:
           
QtGui.QApplication.[sS]etOverrideCursor(QtCore.Qt.CursorShape.WaitCursor);

although the corresponding:
            QtGui.QApplication.[rR]estoreOverrideCursor();

seems to be compiling ok. Is this my misunderstanding? I did try to
    see if this version of setOverrideCursor would work, but it doesn't
    because of a type mismatch:
            QApplication.OverrideCursor = Qt.CursorShape.WaitCursor;

For the moment, I've commented out both calls in my code but it
    would be good to reinstate them.

Finally, I notice a warning:
            Warning    13    'QtGui.QGraphicsItem.Scale(double,
    double)' is obsolete: '"instead."'    
which I didn't get in PyQt and isn't marked as obsolete in the qt
    4.8 docs - indeed it was only introduced in qt 4.6. 

Regards
Ruth
