Can I integrate the Qt Framework with a S-Function block in Simulink 7.3 (R2009a)?

I want to do my own Qt Visualization with a S-Function block that I generate in Simulink. Is this possible and where do I start?

The Qt Framework is based on a C++ library, so the integration should be similar to other third party C++ libraries.

Qt Framework can deploy applications to a variety of platforms. For Windows, there is an option to build Qt as a shared library

<http://doc.trolltech.com/4.1/deployment-windows.html>

In terms of integrating to S-Functions, you can load these shared libraries and make function calls from the deployed Qt application.

Additionally, Simulink S-Functions have multiple entry points. This means that depending on the action being called in Simulink, it calls a certain portion of the code in S-Function.

Therefore, users should be aware of the S-Function structure when interfacing with Qt function calls.

However, please note that one cannot simply link against the Qt libraries that are already included in the MATLAB installation.
