<dt><a name="newButton"><code>(newButton Able Dst Args)</code></a>
<dd>This function makes a button used to create a new object. The following
code comes from the demo app supplied with the PicoLisp distribution, in
gui.l, and makes a button that when clicked creates a new object of the
class <code>+CuSu</code>. The new object is initialised with the values used
in a search for an existing one, if any such terms have been entered.
<pre><code>
(newButton T Dst '(+CuSu)
'(nr genKey 'nr '+CuSu)
'nm *CuSuNm
'plz *CuSuPlz
'ort *CuSuOrt
'tel *CuSuTel
'mob *CuSuMob )
</code></pre>

object can be edited.
