Vitrail

This paper describes the implementation of a window manager called 'Vitrail'. Vitrail has been designed with a highly modular and open architecture allowing activities to interface to it at various levels while favouring overall consistency in the interface that is presented by these activities to the user. The most interesting module is the outermost, which handles the user interface of the window manager and facilitates the exchange of information between the user and the various activities. In addition, it permits information exchange among the various activities themselves.
