Well, width gets called on whatever self is if you don't call it on an
object explicitly. Since self is always the Shoes::App in shoes, simply
calling width() gives you the width of the shoes window. However, I've
apparently got a little bit of confusion myself:
Shoes.app :width => 1200 do
@s = stack :width => 300 do
para "value of self inside the stack: #{self}"
para "class of @s inside the stack: #[email protected]}"
end
para "class of @s outside the stack: #[email protected]}"
para "Width outside the stack: #{width}"
para "Width inside the stack: #[email protected]}"
end
The value of @s does not get "set" until the stack is closed in this case
and so @s.class evaluates first to nil and then later to Shoes::Stack once
the stack has been closed. But, @s.width gives me 0 once outside the stack.
Also, by way of the example in the manual under "Elements: Common width() >>
a number", I am led to believe that one should be able to reference @s
within the block. Is this possibly a bug with my version (REVISION = 1057)?
Cheers
