This does NOT answer you question, but...
have you considered using FastREPORT instead of QuickReport?
it has:
- IBO native dataset compatibility (me and others are improving and mantaining this part, together with the author)
- CLX version, so it runs with Kylix too
- cheap with source ($99), end user report designer included

Have a look at:
http://www.fastreport.ru/en/
or
http://www.fast-report.com/en/
I'm using it and I'm satisfied, but you have to try it by yourself :)
