What is ClassyTcl
ClassyTcl is a dynamically loadable
object system for
Tcl. A Tcl-only as well as a C implementation
is available. It also doesn't require patches to the Tcl core, so
keeping up with new releases should be easy. Performance is very
adequate. The C version is gives extra speed, and makes it possible
to implement some methods in C.
In contrast to other Tcl object systems for Tcl, it is not modeled after
the object system designed for a completely different language such a C.
IMHO, it better follows the Tcl philosophy. The system is simple, but
flexible. Classes and objects are dynamic, and can easily be queried,
changed and debugged at runtime.
What is ClassyTk
The ClassyTk is an extension of Tk based on the
ClassyTcl Object system.
Gui Builder
The ClassyTk Builder can be used to graphically
create interfaces. It is invoked via the cbuild command in the bin
directory.
Widget Set
ClassyTk adds a lot of improvements to Tk, ranging from drag
and drop support (between Tk apps) and a configuration
system to a large set of new
widgets and commands, written using the object system.
While the object system itself only requires Tcl (>8.0), the widgets that come with it
require Tk (of course), and another freely available extension called
ExtraL. ExtraL also does not require
compiled code, but can be speeded up by having it available.
Documentation for the widgets is often somewhat limited, but besides
the documentation, you can learn a lot from sources, the tests and the demos.
Sample applications
The ClassyTk distribution contains some example applications:
- cedit: This editor is actually very useable: I use it for all my developement
- ccalc: calculator; demo for the builder
- cdraw: vector drawing program
- ctester: app to test widgets
- cfiles: unfinished: very early stage file manager
- ccenter: unfinished: very early stage program manager

How to contact me
My mailbox gets overwhelmed quite often, and the development of ClassyTcl
is definately not my only task, so responses might be slower than you
would like. However, I will respond as fast as I can.
