I am trying Lispbox on Windows 2000 together with the Lisp Toolkit of
Peter Herth. I am new to Lisp. How do I solve the following name
conflict? I don't get the error using Clisp interpreter outside
Lispbox (Emacs).

CL-USER> (load "c:\\lispbox-0.6\\ltk\\ltk")
T

CL-USER> (use-package :ltk)
(USE-PACKAGE (#<PACKAGE LTK>) #1=#<PACKAGE COMMON-LISP-USER>): 1 name
conflicts remain
Which symbol with name "VALUE" should be accessible in #1#?

   [Condition of type SYSTEM::SIMPLE-PACKAGE-ERROR]
.... ecc. ecc.

Thanks.

Hi,

while I have no idea where the definition of value comes from,
it sounds like a symbol conflict, that is, you try to import
the symbol value from Ltk, which is already defined in your
CL-USER package. To resolve that, you could either try
(unintern 'value) before the use-package or refer to the
Ltk symbols without usepackage as in ltk:with-ltk.

I have another question. Does LTK support double byte characters? I
mean, is there a way (under Windows and setting the appropriate font )
to have for example japanese character displayed on widgets with a
"text property" like button, label, text etc.? It is more a matter of
curiosity, since Tcl and Tk support the Unicode character fonts.
Thanks again.

While Ltk has no explicit support for double byte characters, it
should be no big deal to use them. After all Ltk just sends Tk
commands to wish - so if you can represent Tk unicode characters
in a Lisp printable form, Ltk can use them.
