I dont understand the question....Qt is c++ based.

For what purpose do you want to use Qt in your setup?

You can have it for GUI, XML, Networking, Container classes, core lib like QString and all the like.

You can integrate qt in your existing c++ code for replacing OS dependent API functions by Qt functions to make your application cross-platformed.

I had to do this at work. There is a swarm of available options. The main app is a Google-like X11-based system. I'm in charge of the separate touch-screen-based Qt GUI.

Ideas:

• X11 event loop can be replaced with qt's own one: lenghty, effective.
• Use shared memory between different applications: upload a class full of basic types, then download it on the other end.
• Use TCP/UDP & communicate via ethernet: super-duper-extensive piece of code, but hey, it does the trick!
• Use threads: one for your c++ app, one for the new qt based app. It's OK, but quite unstable (i.e.: X11 crashes when running for 40+ hrs)

Well, that's as far as I can imagine with no additional data :). Post again or PM!

QT is a multiplat formed IDE and u can develop any kind of application using c++,ruby,python,html,xml,javascript etc...
u can developed software like:-
1. os
2. web based
3. mobile apps
4. game
5. multimedia etc

Hi!
If you are new to Qt, you can see an example (2) in this page : http://www.iissam.com/sources/codes.php
If you understand french : http://www.siteduzero.com/tutoriel-3-11406-programmez-avec-le-langage-c.html

Good Luck :)

I had a native C++ simulation classes and I wanted to create an OpenGL Simulation. I just learned how to create a GUI with Qt, and had to create object instances of the classes I created independent from Qt in my program. And that was it!!!
