Alexandros, I suspect that the interesting question is how QT interacts with Clutter / OpenGL(ES) not how it interacts with X.
There is a Clutter-Qt port which embed the default ClutterStage into a parent QtWidget. It has a dependency on X11 though. http://git.clutter-project.org/clutter-qt/
Qt itself provides a good support for OpenGL-ES 1.1/2.0 and OpenVG 1.0/1.1 painting profiles.
I see a swing away from X, not an integration with it, in all the upcoming dominant platforms. That said, a native embedded QT stack is an interesting 'head' and, providing good test cases etc. Dave

Is there a X11 server which can run (perhaps windowed) under QWS? This would be great for compatibility with X apps. Something like Xephyr/Xnest perhaps?
The GUI part of all applications that run under QWS must be written in pure Qt. Unfortunately, I don't know of such an X11 server.
The whole Qt/QWS environment is really targeted for special purpose systems with strict memory constraints that run dedicated UIs. It is not designed to be able to interact with other GUI toolkits and applications.
There is a very old (but still relevant) discussion about this issue:
http://lists.trolltech.com/qt-embedded-interest/2002-10/msg00117.html
The bottom line is that if there is a need for both Qt and general X11 support in a resource-constrained environment, the only feasible way is to use Qt/X11 over a lightweight X11 server (eg KDrive).
Thanks, Alexandros
