Fifth Annual Tcl/Tk Workshop, 1997 ## The Tycho User Interface System Christopher Hylands, Edward A. Lee, H. John Reekie School of Electrical Engineering and Computer Sciences University of California - Berkeley ### Abstract Tycho is the next-generation user-interface system we are building for the Ptolemy project. It is a complete [incr Tcl] application structured as an extensible class library. Our goal is to make it easy to extend this basic application with functionality and a user interface for specialized applications such as electronic design and simulation. The Tycho library includes a selection of general-purpose widgets, syntax-sensitive text editors, and graphical editing support. It incorporates architectural features that make it easy for different editors and viewers to share data and screen space. Finally, structured support for incorporating C and Java packages into this framework allows us to use those languages to complement the scripting and user-interface features of Tcl/Tk.
