[MacRuby-devel] windowControllerDidLoadNib strangeness

Fri Nov 26 14:22:46 PST 2010

i jumped the gun...
The problem is in my code that uses the MRGraphics library..
since I removed that, but kept in all of the MRGraphics files, and required
it.
So they are compiling alright, but the

  def drawRect(rect)

@theSteps ? @theSteps : @theSteps = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12,
13, 14, 15, 16] # initial setup / default view values

@theStartstep ? @theStartstep : @theStartstep = 1

@theNumsteps ? @theNumsteps : @theNumsteps = 16

     dimensions = [CGRectGetWidth(rect), CGRectGetHeight(rect)]  #
MRGraphics setup code

    Canvas.for_current_context(:size => dimensions) do |c|

stepboxes = Path.new         # declare objects to be drawn

  highlightedRange = Path.new

  cursor = Path.new

  start = (@theStartstep-1)%16  # calculate highlighted range

  length = @theNumsteps

      if (start+length > 16)

        highlightedRange.rect( start*29, 0, ((16-start)*29)+4, 162 )

        highlightedRange.rect( 0, 0, (start+length-16)*29, 162 )

      else

        highlightedRange.rect( start*29, 0, length*29, 162 )

      end

  cursor.rect( (start*29)-1, 0, 1, 162)  # calculate location of the
vertical cursor

      @theSteps.each_with_index do |k, i|   # calculate locations of the 16
step-boxes

        stepboxes.rect( i*29, k*9, 29, 9 )

      end

  c.background(Color.gray)     # paint background

  c.fill(Color.blue)         # paint highlighted range

  c.draw(highlightedRange)

  c.fill(Color.yellow)  # draw step-boxes

          c.stroke(0)

          c.stroke_width(1)

  c.draw(stepboxes)

  c.fill(Color.black)  # draw cursor

  c.stroke_width(0)

  c.draw(cursor)

    end

  end
