Yup. Just make your own basic widget classes and pass the Shoes app to their
constructors.

Hi Patrick and folks,

How about this one?
I'm not sure this is what you want to do, though...

Shoes.app do
  stack top: 30, left: 30, width: 300, height: 300, scroll: true do
    100.times do |i|
      flow do
        bg = background(pink).hide
        para "phone number #{i}"
        hover{bg.show}
        leave{bg.hide}
        click{alert "hi! no.#{i}"}
      end
    end
  end
end

Hope this helps,
ashbb

yeah, that's what he wants… problem is, if the list is huge, Shoes takes a
long time to redraw (it draws everything, not just what's on screen :-( )

Ohhh,.... You are right.
Umm... okay, how about the following?
This is not an ultimate solution, but a bit more good, IMHO. ;-)

Shoes.app do
  bgs = []
  9.times do |i|
    bgs << background(pink, top: 30+34*i, left: 30, width: 270, height:
30).hide
  end

  s = stack top: 30, left: 30, width: 300, height: 300, scroll: true do
    1000.times{|i| para "phone number #{i}"}
  end

  9.times do |i|
    flow top: 30+34*i, left: 30, width: 270, height: 30 do
      border black
      hover{bgs[i].show}
      leave{bgs[i].hide}
      click{alert "hi! no. #{s.scroll_top.zero? ? i : (s.scroll_top + 10) /
34 + i}"}
    end
  end
end

Cheers,
