Tk Bwidget on windows

Ruby
#1

Hello, I am trying to do a progress bar via the Tk BWidgets thing and
the following line taken from the (otherwise extremely helpful)
tutorialspoint ruby examples…

require ‘tkextlib/bwidget’

…gives an error “TkPackage can’t find package BWidget”.

I am using ruby 193 on Windows. Any clues much appreciated. The normal
Tk things all seem to work fine… just stuck with the progressbar!

Does bwidget work from tk code (not ruby)? Maybe there’s something
missing in the tk installation?

I’m not a Tk guy, but this works for me on 1.9.3p0 on Win7 32bit:

require ‘tk’
require ‘tkextlib/tile’

TkT = Tk::Tile

root = TkRoot.new { title ‘Progressbar Demo’ }
content = TkT::Frame.new(root) { padding ‘3 3 12 12’ }.grid(:sticky =>
‘nsew’)
TkGrid.columnconfigure(root, 0, :weight => 1)
TkGrid.rowconfigure(root, 0, :weight => 1)

p = TkT::Progressbar.new(content) do
orient ‘horizontal’
length 200;
mode ‘determinate’
end.grid(:column => 1, :row => 1, :sticky => ‘we’)

position = TkVariable.new
position.value = 20
p.variable = position

Tk.mainloop

Fail fast. Fail often. Fail publicly. Learn. Adapt. Repeat.

Cheers for that. The Tile thing helps a lot. I think I am getting
somewhere now.

Probably you can get BWidget extension from ActiveTcl package.
Please copy BWidget library files on ActiveTcl to your Tcl/Tk (which is
used on your Ruby/Tk) library path.

Please try to run /tkextlib/pkg_checker.rb.
It will show which extension is available on your Ruby/Tk.

You can get a pure Ruby/Tk (with standard Tcl/Tk only) version of
progressbar widget class (progressbar.rb) at
http://www.dumbo.ai.kyutech.ac.jp/~nagai/RubyTk/?����¾�Υ����ץ륹�����ץ�
(the page is written in Japanese).
It is an example of usage of place geometry manager and how to make a
composite widget class.
