Abstract
In this paper we describe an approach to wrapping a preexisting C++
class library into the interpreted Tcl environment. Specifically, we
look at our efforts over the past two years to add the Tcl interpreted
environment on top of the Visualization Toolkit which consists of over
three hundred C++ classes. We address how we overcame the fundamental
issues involved in wrapping existing C++ code and what limitations we
had to accept. We contrast our approach to other Tcl object oriented
extensions such as Object Tcl and [incr Tcl] and explain why they were
not suitable. We conclude by looking at future directions for our
work.
