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:

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
