Hi Ruby Student,
I tried subscribing to shoes@librelist.org but it was impossible!
`.org`?
I'm not sure it's okay or not.
But according to this Librelist web page: http://librelist.com/
You should send your email to shoes@librelist.com.
Try again and if you couldn't subscribe. You may be better to send your mail to meta@librelist.com like this: http://librelist.com/browser//meta/2010/7/28/cannot-subscribe-flask-librelist-com/
I am attaching my image so you can analyze it and comment on it.
The image was rejected by the ruby forum.
Could you upload the image to some free web site?

how can I tell Shoes to place them on the center of the pane,
without having to specify margin?
How about the following?
Shoes.app do
five_buttons_width = (46 + 2) * 5
seven_buttons_height = (40 + 2) * 7
flow :width => five_buttons_width,
:left => (width - five_buttons_width) / 2,
:top => (height - seven_buttons_height) / 2 do
%w(7 8 9 + sin
4 5 6 - cos
1 2 3 * sinh
tan cot 0 ln /
cosh Exp log tanh =
Mod n! sqrt x*2 x*y
% e Pi Clr Ce
).each do |btn|
button(btn, :width => 46, :height => 46){}
end
end
end

using a stack to keep items within a flow one on top of the other
Oh, good idea.
But if you need two groups of radio buttons, you should add something like this:
Shoes.app do
flow :margin => 6 do
radio :a; para strong("512b BK")
radio :a; para strong("1K BK")
radio :a; para strong("MB")
radio :a; para strong("GB")
radio :a; para strong("TB")
stack
radio :b; para strong("Deg")
radio :b; para strong("Rad")
radio :b; para strong("Grad")
radio :b; para strong("DEC")
radio :b; para strong("HEX")
radio :b; para strong("BIN")
end
end
Or simply use two flows in one stack like this:
Shoes.app do
stack do
flow :margin => 6 do
radio; para strong("512b BK")
radio; para strong("1K BK")
radio; para strong("MB")
radio; para strong("GB")
radio; para strong("TB")
end
flow :margin => 6 do
radio; para strong("Deg")
radio; para strong("Rad")
radio; para strong("Grad")
radio; para strong("DEC")
radio; para strong("HEX")
radio; para strong("BIN")
end
end
end

I tried to use the Pi symbol and the square root symbol and
other symbols as caption/lable for the corresponding buttons
Need to add some encoding like this:
Shoes.app do
root = [8730].pack 'U'
pi = [928].pack 'U'
button root.force_encoding "UTF-8"
button pi.force_encoding "UTF-8"
end
You can find unicode number on this website:

What is the difference between para and caption?
Almost the same, except font size.
Look at Shoes manual: http://shoes.heroku.com/manual/TextBlock.html

How can I reduce the space between flows?
Umm,.. I'm not sure what you want to do. Does the following help you?
Shoes.app do
flow{para 'aaa'}
flow{para 'aaa'}
flow(height: 20){para 'aaa'}
flow(height: 20){para 'aaa'}
end
Cheers,
