<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.
