Hi Marc, hi Jim,

I finally touched the khtml_part problem. Here is my mod:

--- ../PyKDE-3.3.2.orig/sip/khtml_part.sip  2002-08-21 20:08:45.000000000 +0200
+++ ./sip/khtml_part.sip    2002-10-16 13:02:32.000000000 +0200

        QRect r;
        int i = 0;
 
-       if (sipParseArgs(&sipArgsParsed,sipArgs,"mJ0J0ii",sipThisObj,sipClass_KHTMLPart,&ptr, sipClass_QPainter, p,
-           sipClass_QRect, r, i))
+       if (sipParseArgs(&sipArgsParsed,sipArgs,"mJ0J0JOi",sipThisObj,sipClass_KHTMLPart,&ptr, sipClass_QPainter, p,
+           sipClass_QRect, &r, i))
        {
            bool b;

At least, it compiles, but does this make sense also? 
I moderately sure about the missing &, which fixes the compiler complaint, 
but what about this sip argument format string?

Please comment!

Thanks,
Hans-Peter
