The interface to Tcl/Tk was integrated in the distribution of
Objective CAML 3.04, and is available for Unix and Windows.
The installation provides one new command: labltk, which
launches a toplevel interactive loop integrating the LablTk
The LablTk library defines a large number of modules, and
heavily uses the language extensions of Objective CAML 3.04. A detailed
presentation of this module falls outside the scope of this appendix,
and we invite the interested reader to refer to the documentation of
Objective CAML 3.04.
There is also an interface with Gtk, written in class-based style,
but it is not yet part of the Objective CAML distribution. It should
be compatible with Unix and Windows.
