14. Develer & Python
Using Python since 2002:
✔ Style: elegant and dynamic language
✔ We have been suggesting it to customers ever since
✔ We have been using for our internal tools
Benefits of Python:
✔ Rapid prototyping (fast development)
✔ High portability (desktop and embedded)
✔ Faster deploy ever

15. Develer & Nokia Qt
Using Qt since 2002
✔ And proudly so!
✔ We have been suggesting it to customers ever since
✔ We have been using for our internal tools
✔ LGPL License

✔ Qt/Windows, Qt/X11, Qt/Mac
✔ Qt/Embedded on Linux and Windows CE

16. Develer & PyQt
Using PyQt since 2004:
✔ Perfect match: bringing Qt philosophy into Python elegant and
dynamic language
✔ Many contributions to PyQt development (debugging and testing)
Benefits of PyQt:
✔ Rapid prototyping (fast development)
✔ Write once, run anywhere
✔ Useful C++ portability layer (QtCore)
✔ LGPL License as Qt

17. Develer & BeRTOS
We create BeRTOS in 2001:
✔ We have been suggesting it to customers ever since
✔ We have been using for our internal tools
✔ Direct BeRTOS development (coding, debugging and testing)
Benefits of BeRTOS:
✔ Open source and royalty free also for commercial projects
✔ Windows SDK with toolchains and IDE integration
✔ Multiplatform Wizard for projects configurations
✔ Not only kernel: ready to use HW drivers for many peripherals

18. Case Studies
CAD for fashion designers
( Python | PyQt | Qt )
Medical diagnosis appliation
( Python | PyQt | Qt widget )
Domotic Control Panel
( C++ | Qt )

19. CAD for fashion designers (1/2)
We provide software consulting for an
Italian company, leader in a particular
field of fashion design.
One of them is a CAD almost entirely
written in Python, which uses PyQt to
fully take advance of the Qt framework.
Effort: 50 man/months (and running...)

20. CAD for fashion designers (2/2)
Heavily customized UI
● Best experience possible for designer: Comply to several (often
odd) habits.
● Qt gives us the flexibility to tweak the UI as we wish, keeping the
code maintainable.
Full OpenGL acceleration
● Drawing canvas are accelerated with OpenGL (QtOpenGL).
● Some parts (eg: texts) use QPainter over OpenGL

21. Medical diagnosis application (1/2)
Customer needed to bundle an application
with the new version of their flagship product.
Introducing PyQt allowed us to complete the
first prototype of the application within one
month from starting from scratch, and to
deliver the final version after just two months
later.

22. Medical diagnosis application (2/2)
Database interaction
● We exploited Qt widgets' flexible API to produce a thin Python layer
that handles reading and writing values from/to DB.
Full i18n support
● Application is deployed in several markets (including Korean and
Turkish ones)
● Usage of Qt made adding i18n support trivial.

23. Domotic Control Panel (1/2)
We provide software consulting for a
big domotic Italian corporate.
The product is developed in C++ and
the GUI is designed with Qt.
It runs on a custom ARM-based
board, with Linux.

24. Domotic Control Panel (2/2)
Home control
● The system controls all the house: lights, security, windows,
home theater
Touch screen interface
● With the easy-to-use interface (realized with a touch screen
device integrated with Qt) the user can control all sensors and
actuators in the house
i18n
● The user interface is multi language and supports European,
Chinese and Arabic languages
