AVC is a multiplatform, fully automatic, live connection among graphical interface widgets and application variables for the python language. AVC supports in a uniform way the most popular widget toolkits: GTK+, Qt, Tk, wxWidgets. The Swing widget toolkit for the java environment is also supported via the jython compiler. AVC is a python package that can be imported by any python or jython application.

The display and the control of some application data through a GUI (Graphical User Interface) is a central problem in GUI programming, it absorbs a relevant part of the programming effort. AVC makes this programming very easy, far more easy than traditional solutions based on MVC (Model View Controller).
