Reports in Qt 4 via OpenOffice

Question

Qt

Actually, how to cross OpenOffice, and in particular OOoSDK and a program written in Qt 4.
In fact, a report generator is required, but such as NCReport and OpenRPT are not suitable, for many reasons. In principle, I don’t even follow cross-platform, but I need to print complex reports (invoices, TORG-12, etc., which I could not solve using NCreport).
I hope that someone has already solved this problem. I found a solution to work directly with ods, odt files on the net, but I would like to have more options for working with reports on openoffice.
How to link OOoSDK with Qt4, or another way to generate complex reports?
Thank you!
