Besides methods specific to particular kinds of FORMS objects, all
FORMS objects also have the following methods:
<dl><dt><table cellpadding=
"0" cellspacing=
"0"><tr valign=
"baseline">
<td><nobr><b><tt id='l2h-
5168' xml:id='l2h-
5168'
class=
"method">set_call_back
</tt></b>(
</nobr></td>
<td><var>function, argument
</var>)
</td></tr></table></dt>
Set the object's callback function and argument. When the object
needs interaction, the callback function will be called with two
arguments: the object, and the callback argument. (FORMS objects
without a callback function are returned by
<tt class=
"function">fl.do_forms()
</tt>
or
<tt class=
"function">fl.check_forms()
</tt> when they need interaction.) Call this
method without arguments to remove the callback function.
