Lkup GUI

lkup-gui.ss

The teachpack lkup-gui.ss implements three functions:

  • control : -> symbol
    to read out the name that a user typed into the query field
  • view : (union string symbol) -> true
    to display its argument in the message panel
  • modelT = (button% event% -> true)
    connect : modelT -> true
    to connect a controller with the Check button
    displays frame

    • Example: 

    (connect 
 (lambda (e b)
   (view (control))))
    This example simply mirrors what the user types in to the message field.
