Please, don't mix the pascal headers from interfaces/qt/qt44.pas with
the c++/c bridge from Den.

There are several layers:

4. [ qtint.pas ] -> main unit of the Lazarus qt interface
calls
3. [ qt4.pas ] -> pascal headers for libqtinf4 (in 4.3, 4.4, 4.5 flavor)
calls
2. [ libqtintf4 ] -> a c++ / c library to flatten the c++ qt core libs
calls
1. [ qt core libs ] <- created by TrollTech

1. is available in most distroes
2. is created by Den Jean and packaged by Matthias
3. is distributed with Lazarus, but can be moved to fpc/packages/qt in
the future
4. is part of Lazarus: the LCL interface with QT.
