Oups,
A solution with instance_eval() :

        def show_popup(title,w=400,h=200,&blk)
         Shoes.app(:title=> title,:width=>w,:height=>h) do
            stack do
                @box=stack :height=>(h-40)do
                  title "#{title}..."
                  instance_eval(&blk)
                  #-------------------------
                end
                flow :width=> 400 do
                    button("Exit",:width => 200) { self.close_dialog }
                end
            end
         end
        end
