Subject: [ruby-talk:17637] TkPhoto on a button

Ruby/Tk question for you all.

I was trying to add an image to a couple of buttons
(following the _Learning Perl/Tk_ book) and tried
this basic format (see below).

Trouble is, it doesn't seem to have heard of TkPhoto.
I found a TkPhotoImage referred to in one of the *.rb
files, but that didnt' work either.

Those who know Tk, does this generally look correct?

# ...
leftImg = TkPhoto("file"=>"left.gif")
rightImg = TkPhoto("file"=>"right.gif")

TkButton.new(bottom) do
  image leftImg
  command proc { blah blah blah... }
  pack $params
end

TkButton.new(bottom) do
  image rightImg
  command proc { blah blah blah...  }
  pack $params
end
