I do not think it is a bug:
----in case of cell1 you create a widget with a hash which specifies
its dimensions to h=100 and w=100 and than you start to paint
starting from 100(x) etc so de facto you are painting outside the
widget display area. If you change your paint method to:
def paint
fill(white)
rect(0, 0, @width, @height)
line(0, 0, @width, 0)
line(0, 0, 0, @height)
line(@width, 0, @width, @height)
line(0, @height, @width, @height)
end
everything is OK, right?
----for cell2 you do not specify any widget parameters explicitly so
it is an "open" slot onto which you paint rectangle and lines and
use up as much space as necessary.
This is how I understand what happens.
Hope it helps

Hello,
Could you point me what's wrong here?
The code:
class Cell1 < Shoes::Widget
def initialize(opts={})
@x = opts[:x]
@y = opts[:y]
@width = opts[:width]
@height = opts[:height]
paint
end
def paint
fill(white)
rect(@x, @y, @width, @height)
line(@x, @y, @x + @width, @y)
line(@x, @y, @x, @y + @height)
line(@x + @width, @y, @x + @width, @y + @height)
line(@x, @y + @height, @x + @width, @y + @height)
end
end
class Cell2 < Shoes::Widget
def initialize(x, y, width, height)
@x = x
@y = y
@width = width
@height = height
paint
end
def paint
fill(white)
rect(@x, @y, @width, @height)
line(@x, @y, @x + @width, @y)
line(@x, @y, @x, @y + @height)
line(@x + @width, @y, @x + @width, @y + @height)
line(@x, @y + @height, @x + @width, @y + @height)
end
end
Shoes.app do
cell1(:x=>100, :y=>100, :width=>100, :height=>100) # doesn't work!!
cell2(100, 100, 100, 100) # works ok
end
The paint methods are the same.
Is it a bug? Why it doesn't work while passing a hash? The console
says nothing.
As usually any help will be blessed.
kind regards
