{ (define LIBNAME "Lkup GUI")
  (include "head.tinc") }

<p>The teachpack <code>lkup-gui.ss</code> implements three functions:
<menu>
<li> <code>{(idx control)} : -> symbol</code> <br>
     to read out the name that a user typed into the query field

<li> <code>{(idx view)} : (union string symbol) -> true</code> <br>
     to display its argument in the message panel

<li> <code>modelT = (button% event% -> true)</code> <br>
     <code>{(idx connect)} : modelT -> true</code> <br>
     to connect a controller with the Check button displays frame
</menu>

<p>Example:
<pre>
(connect
 (lambda (e b)
   (view (control))))
</pre>
This example simply mirrors what the user types in to the message field.
