Line formattting

I spent a few hours playing around and came up this user widget to format lines.

class Row < Shoes::Widget
  attr_accessor :width, :align, :color, :back, :font, :size
  
  def initialize(fmts)
    @width = []
    @align = []
    @color = []
    @back = []
    @font = []
    @size = []
    fmts.each do |f|
      @width << f[:width] || 100
      @align << f[:align] || "left"
      @color << f[:color] || black
      @back << (f[:background] ? f[:background] : white)
      @font << (f[:font] ? f[:font] : "Arial")
      @size << f[:size] || 12
    end
  end
  
  def create(values)
    flow do
      values.each_index do |i| 
        flow width: @width[i] do
          background @back[i]
          para values[i], align: @align[i], stroke: @color[i], font: @font[i], size: @size[i]
        end
      end
    end
  end
  
end

Shoes.app resizable: true do
  @r = row [{width: 40, align: "right", color: green},
            {width: 100, align: "left", color: black},
            {width: 200, align: "center", color: blue},
            {width: 50, background: lightpink}]
  stack height: 200 ,width: 400, scroll: true do
    @r.create ["1","foobar","really long string"]
    @r.create ["2","not here","sort of a long string"]
    @r.create ["x","hmm","nothing to see"]
    @r.color[0] = red
    @r.create ["error", 12.45, "foo"]
    @r.color[0] = green
    @r.back[1] = lightgrey
    @r.font[2] = "Mono"
    @r.size[2] = 10
    @r.create [5, "oops, this overlows the field", "still working..."]
    @r.back[1] = white
    @r.create [6, 'a', 'b', 'c']
  end
end

It's probably overkill and not powerful enough at the same time.
