The more the CAD tools reflect this need, the more efficient a designer's time will be. The complexity of frequently used operations is directly proportional to the time it takes to refine a design. This paper describes how a well-designed command tool such as Tcl can be used to integrate existing tools and shorten design time. The graphical user interface is automatically generated from the hierarchical cdtML description entered by the user. The tree view provides a simple, compact user-interface for browsing the hierarchy of task instances, their APIs, as well as for their interactive execution.
Data structures are an important part of many computer programs.
Various scripting languages provide different methods for defining these data structures. These are then evaluated on size, performance, readability, and conformance to generally accepted good programming practice. This overview talk discusses the design and implementation of KitView, a user interface tool designed as a test bed for ideas in database design, data management and user interface generation. This presentation describes some extensions to Tcl and Tk that were used to implement tools for the analysis and visualization of large data sets. Such tasks require efficient manipulation of large numerical arrays, and convenient display of three-dimensional data.
