The GINA Interface Builder

As part of the GINA project at GMD, an interface builder has been implemented that can be used to interactively develop graphical user interfaces based on the OSF/Motif toolkit. The interface builder extensively uses direct-manipulation techniques to facilitate explorative learning and to accelerate the definition process. It provides special support for the dynamic layout capabilities of Motif. In particular, it employs a simple ruler model that is mapped onto the more complex native facilities of the Motif form widget. Additionally, the interface builder is able to infer dynamic layout parameters from a static sample layout.
