[pygtk] A Model-View-Controller implementation for pygtk2
Hi all, at http://sra.itc.it/people/cavada/dload/mvc.tar.bz2 can be found an implementation of the MVC pattern for pygtk2. I hope can be particularly useful when developing GTK based GUIs with pygtk and glade. For middle-size and large applications, the result is a more rational, structured domain separation. Also, reuse allows a more rapid prototyping of small and dummy applications. The key idea is (of course) to be able to separate the state of the application (the Model) and the representation for parts ot that state (the View). One or more glade files can be associated with a View, as well as widget hierarchies manually built by developers. In our implementation Model and View do not know each other. In the middle, one or more Controllers are located, which handle signals fired by Views, and notifications of state changes fired by Models. In that sense our implementation is different from classic MVC pattern, but we think it is better integrated with the GTK toolkit. This MVC implementation is an important basement for gNuSMV, the GUI for the Open Source Model Checker NuSMV we are developing. As you can guess (look at the version number 0.1.0! ) it is still an early version. The supplied archive contains the pattern implementation, an example of implementation, and a short document which describes the idea and the architecture. License is LGPL. In the immediate future we will extend it with: - Multithreading support for models. - A better observable properties support.

It covers MVC but goes beyond it in creating a truly Pythonic OO framework for UI apps. It's currently PyGTK-0 based but we have implemented lately some changes that will make the change quite convenient.
