Uiml.net: an open Uiml renderer for the .Net Framework

Abstract

As the diversity of available computing devices increases it becomes more difficult to adapt User Interface development to support the full range of available devices. One of the difficulties are the different GUI libraries: to use an alternative library or device one is forced to redevelop the interface completely for the alternative GUI library. To overcome these problems the User Interface Mark-up Language (UIML) specification has been proposed, as a way of glueing the interface design to different GUI libraries in different environments without further efforts. In contrast with other approaches UIML has matured and has some implementations proving its usefulness. We introduce the first UIML renderer for the .Net framework, a framework that can be accessed by different kinds of programming languages and can use different kinds of widget sets. We show that its properties, among them its reflection mechanism, are suitable for the development of a reusable and portable UIML renderer. The suitability for multi-device rendering is discussed in comparison with our own multi-device UI framework Dygimes. The focus is on how layout management can be generalised in the specification to allow the GUI to adapt to different screen sizes.
