Help with Shoes

Hello Ruby/Shoes World!
As part of my Ruby learning experience I started looking into a GUI
environment.
Shoes appears to be simple enough that I would probably be able to learn it.
I am working on a simple Sudoku solver in Ruby, as a Ruby learning exercise.
To this point I have been using stray ASCII output, but I would like to
beautify it using GUI.

To that effect, I was looking at some of the Shoes sample programs,
specifically the one named calc.
I selected calc because it shows how to place several buttons on a row.
Although the buttons on calc represents the basic symbols of a calculator, I
thought copying the same concept to represents the 9x9 matrix of a "regular"
sudoku puzzle.

The following is the modified code from calc to display the board, and for
which I have some questions:

Shoes.app(:title => " A Humble
Sudoku Solver ", :height => 546, :width => 617, :resizable => false) do
    background "#EEC".."#996", :radius => 5, :top => 2, :left => 2, :width
=> -4, :height => -4
    stack :margin => 0 do
       stack :margin => 0
       btn = "123456789"
       flow :width => 618, :margin => 4 do
          (1..81).each do |n|
               button btn, :width => 66, :height => 66
          end
      end
  end
end

1) - For the title, is there some formatting to tell Shoes to center or
left/right justified a title?
2) - For the background I tried fill green right after the last " (double
quote) but it gave me an error. How could I specified fill green, although I
don't really need it.
3) - What purpose of :radius => 5?
4) - If you are familiar with sudoku, how do you add solid lines to separate
each subgroup of 3x3?

Although I have many more questions, I will continue looking the
documentation, including nks.

Thank you

    background "#EEC".."#996", :radius => 5, :top => 2, :left => 2, :width

    stack :margin => 0 do
       stack :margin => 0
       btn = "123456789"
       flow :width => 618, :margin => 4 do
          (1..81).each do |n|
               button btn, :width => 66, :height => 66
          end
      end
  end
end

1) - For the title, is there some formatting to tell Shoes to center or
left/right justified a title?

For window titles, no. For titles on the screen, use :align =>
"center".

  title "Sudoku Solver", :align => "center"
  

2) - For the background I tried fill green right after the last " (double
quote) but it gave me an error. How could I specified fill green, although I
don't really need it.

You want the background to be green, not a gradient?
Try: background(green)

3) - What purpose of :radius => 5?

In newer versions of Shoes, this is :curve => 5. It curves the
edges of the background rectangle.

4) - If you are familiar with sudoku, how do you add solid lines to separate
each subgroup of 3x3?

You'll want to group the buttons each in their own slot. (A slot is
the generic name for a `stack` or `flow`.)

  Shoes.app(:title => "A Humble Sudoku Solver ", :height => 546,
      :width => 640, :resizable => false) do
    background green

    btn = "123456789"
    9.times do
      flow :width => 206, :margin => 4 do
        9.times do
          button btn, :width => 66, :height => 56
        end
      end
    end
  end

I don't know if this is helpful or just more confusing, but Martin
DeMello recently wrote a crossword builder. Maybe since sudoku and
crosswords are relatives, it might have some ideas you could use?

_why,

Thank you very much for taking the time to answer my questions. It is really
appreciated.
I will also look and learn from Martin's crosswords puzzle.

Thanks again,

Ruby Student
