Most developing solutions ship their report designer with developing kits such as Crystal Report for Microsoft Visual Studio (I'm not sure if they replaced it with Microsoft report designer) and Rave report or Quick report for Delphi

Is there any ability to ship report designer with Qt?

I think this is necessary suggestion because printing rich edit output not so much fun specially for SQL depending programs.

I found just *one* report designer for Qt while the others are dead!
https://sourceforge.net/projects/openrpt

Dead but may interesting:
https://sourceforge.net/projects/exaro/

PS
First thing my friend asked me about after migrating from Delphi to Qt is the Report Designer thus I found this is really a weak point for open source solution.
