Is this what you mean?

    PyObject *elem;   // Points to QRect object type
    QRect *cpp;
    int iserr = 0;

    cpp = (QRect *)sipForceConvertTo_QRect (elem, &iserr);
    if (iserr)
    {
        *sipIsErr = 1;
        return 0;
    }

The only thing that would change in most cases is substituting the particular 
Qt object type of interest for QRect everywhere. The "sipIsErr" is part of 
%MappedTypeCode - probably won't apply most places.
