Subject: Re: Combo boxes in Ruby-Tk

Hi!

In Brent B. Welsh's book "Practical Programming in Tcl  and Tk" 4th  
ed. the index redirects "combobox" to "spinbox" (new in Tcl/Tk  
version 8.4 IIRC):

require 'tk'

TkSpinbox.new do
   from -2
   to 2
   pack
end

TkSpinbox.new  do
   from -2
   to 2
   increment 0.1
   pack
end

TkSpinbox.new do
   @states=["Arizona", "California", "New Mexico"]
   values @states
   wrap 1
   pack
end

TkButton.new do
   text "Quit"
   command "exit"
   pack
end

Tk.mainloop

Hope, that helps.

Julian
