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
