Bruce,
could you post a simple Tk Java sample and the java code that you
generate
using the Jacl script. I am trying to get a handle on what you are
describing and an example would be great.
My initial impression of what a Tk like solution for Java would look
like
is similar to the standard C solution except written in Java. I'm not
quite
sure I understand why a preprocessor/code generator is required. Could
you describe what your design criteria were and what the advantages of
this
approach are ?
regards
Chris
