It seems to me that "@root" in p. 157 , Programming Ruby is an error for
"root."  The following is a complete program I made of the sample code.

require 'tk'
class Picture
  def initialize(root)
    image1 = TkPhotoImage.new { file "img1.gif" }
    image2 = TkPhotoImage.new { file "img2.gif" }
    b = TkButton.new(root) {
       image  image1
       command  proc {doit} }
    b.bind("Enter") { b.configure('image'=>image2) }
    b.bind("Leave") { b.configure('image'=>image1) }
    b.pack('side'=>'left', 'padx'=>10, 'pady'=>10)
  end
end
parent = TkRoot.new{ title 'Pictures' }
Picture.new(parent)
Tk.mainloop

Regards, Takao
