Subject: Using TkTree - Desperately need help

Message-ID: said:
Can anyone give me a step-by-step method of using TkTree on Win32? I
don't know how to make tcltk-ext work, so any help would be
appreciated.
If the 'TkTree' which you said is the script at <
http://wiki.tcl.tk/10615>,
you will not need to use tcltk-ext because there are only 5 commands
introduced by the library.
Although I think you can write a library script for TkTree widgets,
I append a sample library at the end of this mail.
To install,
step1: make TkTree work on Tcl/Tk
(1) save Tcl source script (e.g. 'tktree.tcl').
(2) copy the script file to Tcl/Tk library directory.
(3) start wish or tclsh, and do 'auto_mkindex <library-directory>'.
(4) restart wish, and do the test script at <
http://wiki.tcl.tk/10615>.
step2: try on Ruby/Tk
(1) save the following library script as 'tktree.rb'.
(2) <your ruby path>/ruby tktree.rb
(3) move tktree.rb to your ruby library path.
(4) 'require "tktree"' on your script.

# Note: optional argument '-font' of the Tcl library is changed to
# 'itemfont' on this Ruby library, because of avoiding font
# operation trouble in 'initialize' method ( see the following
# test script ).
