Abstract
One difficulty in software maintenance is that the relationship between observed program behavior and source code is not always clear. In this paper we are concerned specifically with the maintenance of graphical user interfaces (GUIs). User interface code can crosscut the decomposition of applications making GUIs hard to maintain. A popular approach to develop and maintain GUIs is to use What you see is what you get editors. They allow developers to work directly with a graphical design view instead of scattered source elements. Unfortunately GUI editors are limited by their ability to statically reconstruct dynamic collaborations between objects. In this paper we investigate the combination of a hybrid dynamic and static approach to allow for view-based maintenance of GUIs. Dynamic analysis reconstructs object relationships, providing a concrete context in which maintenance can be performed. Static checking restricts that only changes in the design view which can meaningfully be translated back to source are allowed. We implemented a prototype IDE plug-in and evaluate our approach by applying it to five open source projects.
