15.4.3 FORMS Objects
Besides methods specific to particular kinds of FORMS objects, all
FORMS objects also have the following methods:
- set_call_back (function, argument)
 - 
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 fl.do_forms()
or fl.check_forms() when they need interaction.)  Call this
method without arguments to remove the callback function.
 
- delete_object ()
 - 
  Delete the object.
 
- show_object ()
 - 
  Show the object.
 
- hide_object ()
 - 
  Hide the object.
 
- redraw_object ()
 - 
  Redraw the object.
 
- freeze_object ()
 - 
  Freeze the object.
 
- unfreeze_object ()
 - 
  Unfreeze the object.
 
FORMS objects have these data attributes; see the FORMS documentation:
