Subject: Tk and instance variables (pickaxe book Ed 2, p260)

Chaps,

There's a small section of code from the second edition of the pickaxe book on p260.

require 'tk'

image1 = TkPhotoImage.new {file "img1.gif" }
image2 = TkPhotoImage.new {file "img2.gif" }

b = TkButton.new(@root) do #  <---- This line
 # more code
 # not shown for sake of brevity
end
# more code
# more code
  
Am I right in saying that the line that creates the new button has an instance variable that will be used to define the main root "container"?
