TK help

Okay so I set up a greeting AI for my sceince projet, (cool right?) but
I got a problem: when he ask for a new key word I can't 'un-pack' the
button so it's always there then if it happens again :), get ready for
this, it does it again! My fault in the code, but I don't know what else
to do, so here's the code that I think needs the editing:
submit = TkButton.new(text) {
  image submitbutton
  command {
    aa = grem.how_are_you(text_awnser)
    ga.configure("text"=>aa)
    if aa.include?("I don't know what that means")
      submit_helpg = TkButton.new(text){text "New positive keyword";
command {add_word(new_word,"yes")}}.pack("side"=>"bottom")
      submit_helpb = TkButton.new(text){text "New negative keyword";
command {add_word(new_word,"no")}}.pack("side"=>"bottom")
      helpme = TkEntry.new(text){ textvariable new_word
}.pack("side"=>"bottom")
    end
  }
}.pack

Thanks In Advance,

I don't know why you say you can't unpack your button -- it's possible to both unpack and disable buttons, and then repack and re-enable them. Consider the following code:

<code>
require 'tk'

DEBUG =

begin
    root = TkRoot.new {title 'Button Demo'}

    unpack_button = TkButton.new(root) {
       text 'Unpack Me'
       command {unpack_button.unpack}
    }
    unpack_button.pack

    disable_button = TkButton.new(root) {
       text 'Disable Me'
       command {disable_button.state = 'disable'}
    }
    disable_button.pack

    reset_button = TkButton.new(root) {
       text 'Reset'
       command {
          unpack_button.pack('before'=>disable_button)
          disable_button.state = 'normal'
       }
    }
    reset_button.pack

    # Set initial window geometry; i.e., size and placement.
    win_w, win_h = 200, 100
    # root.minsize(win_w, win_h)
    win_lf = (root.winfo_screenwidth - win_w) / 2
    root.geometry("#{win_w}x#{win_h}+#{win_lf}+50")

    # Make Cmnd+Q work as expected. This is for OS X.
    root.bind('Command-q') {Tk.root.destroy}

    Tk.mainloop
ensure
    puts DEBUG unless DEBUG.empty?
end
</code>
