That's what I thought, but then I must change the code I want to run (see
highlighted code)
Shoes.app :height => 260, :width => 250 do
animate(1) do
@time = Time.now
clear do
*$app.draw_background
* stack do
puts "Time = [EMAIL PROTECTED]"
end
end
end
def draw_background
end
end
And would ideally like not change that code...
Am I right?
